What you will find

When a business is still validating its product, building its team or making its first sales, much of its potential value depends on events that have not happened. An investor can recognize an opportunity while keeping projections separate from facts. An investment memo records what has been observed, what the investor expects, how much testing those expectations will cost and the conditions under which committing capital makes sense. Its purpose is to make the reasoning understandable and expose its weaknesses, rather than make the project persuasive at any cost.

01

Turn an initial impression into a decision others can examine

A useful memo answers a specific question: why would this investor commit this amount, through this instrument, to this business, on these terms? Connect the product, founders' capabilities, commercial evidence, use of funds and negotiated rights. A presentation may describe a large market; the memo explains why this team could plausibly serve a particular segment. It also identifies what prevents a firmer conclusion and whether that uncertainty must be resolved before funding or can reasonably be tested afterward.

The decision record complements the memo. The memo contains analysis and a recommendation; the record states what was actually decided, by whom, with which reservations and using which document versions. Conditional approval does not authorize any transfer regardless of outstanding requirements. A corporate restructuring condition, for example, remains open until adequate evidence confirms completion. Keeping analysis, authorization and fulfillment of conditions distinct prevents enthusiasm in a meeting from becoming a broader authorization in people's recollection.

02

Define the investment question and the boundaries of the analysis

Begin with the company, its stage and the decision requested, using direct language. Identify the buyer, problem and use case instead of describing a solution for every small Brazilian business. Scheduling software might initially serve repair shops working with local vehicle fleets. The immediate problem could be delays in approving repair estimates, rather than digitizing the entire operation. That narrower definition determines which interviews, sales and performance measures can meaningfully support the investment case.

State what falls outside the thesis. If the investment depends on recurring software revenue, do not justify the ownership price through a possible future lending operation with no defined structure. Where implementation services accompany software access, separate their revenue and costs. This reveals whether a first sale shows willingness to pay for the product or mainly purchases the founders' customized work. Services can support early learning, provided the memo explains the expected transition and the cost of making delivery repeatable.

Match the depth of investigation to the decision's risks without claiming completeness. Prioritize questions that could change the price, instrument, conditions or willingness to invest. For a newly formed team, commitment and ownership of the code may matter more than detailed market projections. With early sales, customer concentration and collection capacity may dominate. Explain those priorities and record remaining gaps, including issues left unresolved because investigating them would cost disproportionately more than the investment under consideration.

03

Separate facts, hypotheses and interpretations using traceable evidence

A claim helps only when its meaning is clear. Eight paying customers might mean eight signed contracts, eight payments received or eight businesses already using the product in their operations. These are different observations. For each central claim, identify its source, observation period and relevant limitation. A contract establishes an agreed obligation; a corresponding bank record helps confirm collection; usage records show another dimension. None alone establishes satisfaction, renewal or expansion potential.

Use three explicit categories. A fact is an occurrence supported by identified evidence. A hypothesis needs testing, such as whether a repair shop will remain a customer after implementation. An interpretation is a conclusion drawn from the evidence, such as viewing initial adoption as encouraging. This allows disagreement about conclusions without denying observations. It also prevents repeated assumptions from becoming accepted facts in the group's memory. Estimates should state their assumptions and explain how sensitive the result is to changes in them.

An evidence index can link decisive claims to controlled files: commercial contracts, reconciled collections, authorized interviews, corporate documents or product demonstrations. Avoid reproducing unnecessary personal or commercially sensitive information in every memo version. Restrict access and identify the version examined. Where a source is only a founder's statement, say so. Lack of independent confirmation does not automatically make it false, but should limit its evidential weight and help define the next verification.

04

Assess founders against the work the business needs done

Founder experience is more than a list of previous roles. Relate each person's background to immediate tasks: building the product, selling to the chosen customers, implementing without exhausting capacity and managing cash. Experience at a large company can provide useful knowledge without showing an ability to sell under an unfamiliar brand. Deep sector knowledge does not establish team leadership. Identify capabilities demonstrated in practice and those still dependent on recruitment or development.

Look for concrete sequences of execution and learning. A founder who interviewed customers, changed the approval workflow and shortened implementation provides a potentially verifiable chain of problem, action and result. Compare the account with demonstrations, records and professional references, respecting access and privacy boundaries. Examine availability, commitment, other activities and previous obligations that could affect the project. The relevant question is whether the team can deliver the next milestones with the proposed resources and time.

Examine the relationship between founders separately. Who decides on product, sales and spending? How are disagreements resolved? What happens if someone reduces their involvement or leaves? Equal ownership does not replace clear responsibilities, and a larger holding does not establish future contribution. Record existing agreements, unresolved matters and mechanisms requiring appropriate professional advice. If the thesis depends heavily on one person's continued involvement, identify that concentration explicitly and address it in the conditions and continuity plan.

05

Read early sales without treating them as proof of scale

Early sales are particularly informative when they reveal who buys, why, at what acquisition cost and with how much delivery work. Consider a fictional software company serving Brazilian repair shops, with two founders and eight paying customers. Those customers count as an established fact only after checking relevant records. Selling to similar shops remains a hypothesis. Sales to personal contacts or on exceptional terms do not, by themselves, demonstrate a repeatable commercial process.

Reconstruct selected sales from first contact through collection. Identify the lead source, decision maker, negotiation period, discount, implementation work and support required. Separate subscriptions from services, invoiced amounts from collected cash, and contracted revenue from expected renewals. Show any concentration where two customers account for a large share of receipts. Estimate manual work performed by the founders to deliver the promised outcome. That effort may be justified for learning, but belongs in the capacity and cost analysis.

Choose the next commercial evidence that would strengthen the thesis. Possibilities include winning customers outside the founders' network, collecting a second bill from a comparable customer group or implementing new accounts with fewer hours of work. Each tests a different uncertainty. Registrations, demonstrations and proposals help explain the sales process, but do not replace contracts and collections. A credible thesis acknowledges continuing learning and specifies which learning matters, rather than labeling every increase as validation.

06

Choose the instrument before discussing its economic outcome

Equity, convertible instruments and loans allocate rights and risks differently. Equity involves ownership under the applicable documents, with exposure to the value of that interest and no assumed periodic payment or available exit. A convertible requires clear conversion rules, triggering events and consequences if conversion never occurs. Debt creates payment obligations that may strain a business without sufficient cash generation. The commercial label used in negotiations cannot replace reading the contract and establishing its legal character.

For a convertible, explain the economic formula, including the calculation base, treatment of other instruments and conversion events. Merely mentioning a discount or valuation cap is insufficient. Address what happens if the expected financing round never occurs. For debt, identify the source of repayment, obligations and consequences of default. Receivables financing also requires its own examination of eligible claims and terms. Existing, eligible receivables differ from hoped-for sales: a sales forecast does not itself create a collectible claim available for financing.

The business's legal form may prevent the proposed structure. A Brazilian MEI cannot admit equity partners while remaining a MEI; an equity transaction requires an appropriate business structure before admission. A donation to a nonprofit is not equity or a promise of financial return. Record incompatibilities and obtain competent legal and accounting guidance. The numerical example here assumes a company legally able to admit equity holders, without implying that any business registration permits the transaction.

07

Build the cap table from ownership and existing commitments

A cap table records ownership, but is useful only if it reflects the relevant legal and economic position. Start with current holders, their quotas or shares and the total outstanding. Then identify options, promised interests, convertibles and other commitments that could change ownership. A founders' spreadsheet is a starting point. Compare it with available documents and record discrepancies so the investor can distinguish formal ownership from potential changes already promised.

In this hypothetical example, the company has 120,000 quotas: founder A owns 72,000, or 60%, and founder B owns 48,000, or 40%. No other instruments or commitments enter the calculation. An investor proposes R$ 300,000 through a capital increase at a pre-money valuation of R$ 1,200,000. The arithmetic price is R$ 10 per quota, producing 30,000 new quotas. After investment there would be 150,000 quotas and a post-money valuation of R$ 1,500,000. A would hold 48%, B 32% and the investor 20%.

These percentages follow the stated assumptions; they do not establish a fair price. The money enters the company, with no sale of founders' quotas. A secondary purchase would direct money differently and must be shown separately. Nor does the valuation mean someone would buy the whole company for that amount. Explain how the price was negotiated, which uncertainties it incorporates and why the investor accepts the exchange of capital for ownership. Correct arithmetic alone does not demonstrate an attractive investment.

08

Show dilution step by step and identify who bears it

Initial ownership does not describe the full economic exposure. Hiring arrangements and later rounds may dilute holders. Continuing the example, suppose that after investment the holders approve an equity plan for the team equal to 10% of ownership after implementation. For simplicity, treat the plan as fully issued. Existing holders retain the remaining 90% in the same relative proportions: A falls from 48% to 43.2%, B from 32% to 28.8%, and the investor from 20% to 18%.

Now assume a later R$ 600,000 round at a R$ 2,400,000 pre-money valuation and R$ 3,000,000 post-money valuation. The new investor receives 20%; previous holders collectively retain 80%. A holds 34.56%, B 23.04%, the first investor 14.4%, the team plan 8% and the new investor 20%, totaling 100%. This simulation includes no exercise of participation rights and no additional contribution from the first investor. Either change would require recalculation.

Sequence matters. Establishing the team plan before the first investment, or requiring a particular group to bear its dilution, would produce different results. Always specify the calculation base and timing behind a promised percentage. Rights to participate in later issuances may require additional cash and depend on their terms; they do not automatically preserve ownership. A higher later valuation creates no liquidity for the first investor. A smaller percentage might represent a more valuable interest, depending on actual business progress and eventual exit terms.

09

Connect the money to a timeline and the next decision

Use of funds should explain the learning period the investment finances. Assume the same company starts with R$ 40,000 in available cash and receives the full R$ 300,000, giving an opening balance of R$ 340,000. All following figures are hypothetical planning assumptions. Projected receipts over six months are R$ 15,000, R$ 20,000, R$ 25,000, R$ 30,000, R$ 35,000 and R$ 40,000, totaling R$ 165,000. Outflows are R$ 55,000, R$ 55,000, R$ 60,000, R$ 60,000, R$ 65,000 and R$ 65,000, totaling R$ 360,000.

The resulting month-end balances are R$ 300,000, R$ 265,000, R$ 230,000, R$ 200,000, R$ 170,000 and R$ 145,000. This models actual cash movements, with no profit distributions or return payments to the investor. Include expected commitments, including transaction documentation and monitoring costs; omitted obligations inflate the apparent balance. Even R$ 145,000 remaining does not establish the remaining cash runway without assumptions about later receipts, spending and concentrated payments.

Schedule the next decision before cash becomes urgent. At the end of month three, management could review retention, implementation effort and sales beyond the founders' network. The projected R$ 230,000 balance provides context for continuing, changing course or reducing expenses. The later round in the dilution example is a separate ownership simulation: it is neither included in this cash flow nor assured. Present spending must not depend on treating an uncompleted fundraising as available cash.

10

Make milestones verifiable tests of learning

A useful milestone combines an expected outcome, evidence, a relative deadline and responsibility for measurement. 'Complete commercial validation' is vague. Showing that a defined customer group continued paying after implementation can be examined if the observation window and billing conditions are clear. For the example company, a month-three review could identify which of the original eight customers remain active, which payments became due and were collected, and support hours per account. This connects retention with operational capacity.

Another milestone might test acquisition by securing four customers with no previous relationship to the founders and recording lead source, negotiation, price and implementation. Four is a hypothetical management choice, not a universal validation standard. Its usefulness lies in testing sales beyond personal contacts. Anticipate alternative interpretations: four contracts involving exceptional discounts and customized delivery may support a different conclusion from four customers buying the intended offer on comparable terms. Evidence quality matters alongside the count.

If capital is released in tranches, specify each disbursement condition, who verifies it and how disagreements are resolved. Tranches reduce initial exposure but can undermine the company's ability to plan hiring and delivery. Do not require an outcome that depends on resources withheld in a way incompatible with the plan. The cash example assumes full upfront funding; staged funding requires a new forecast. Milestones should support learning and decisions without creating controls that prevent the funded hypothesis from being tested.

11

Negotiate information rights that provide usable visibility

Information rights should reflect what the investor needs to monitor and what the company can consistently produce. A concise monthly package might cover reconciled cash, receipts and payments, budget comparisons, active customers, overdue collections and milestone progress. Define indicators consistently. An active customer might require actual use and a current contract; combining free and paying users without identifying them distorts interpretation. Record frequency, delivery deadline, responsible person and expected format.

Unrestricted access to every system is rarely the only way to reduce information gaps. It can expose personal data, trade secrets and customer information while creating operational risks. Prefer access proportionate to the purpose, summarized documents and a process for additional checks. Define confidentiality, authorized recipients and whether advisers with appropriate duties may receive information. Where an investor also holds interests in competitors, address that conflict by restricting sensitive details where necessary and specifying how aggregate information will be supplied.

Specify the response to late or inconsistent reporting. A process might begin with clarification and a correction deadline, followed by a joint review if problems recur. Contractual consequences depend on the negotiated structure and require legal assessment. The practical aim is early detection, while keeping reporting demands manageable. Estimate preparation costs and identify essential information that must remain available if growth disappoints or expenses must be reduced. Rights that cannot be exercised usefully provide less visibility than their wording suggests.

12

Define the investor's role and preserve management responsibility

Close involvement does not mean continuous informal control. Distinguish management decisions, matters reserved for equity holders and voluntary investor contributions. Founders might continue choosing routine suppliers and organizing sales activity, while corporate changes and specified significant transactions follow agreed approval procedures. Governance must fit the company's size. Requiring everyone's consent for every expense can obstruct execution and make responsibility for results harder to assign.

Record the assistance supporting the thesis and how firmly it is committed. If the investor offers sales experience, specify whether that means a monthly meeting, proposal reviews or introductions to prospective customers, with the relevant parties' permission. An introduction does not guarantee a sale. Vague promises to open doors can influence founders to accept economic terms for benefits they cannot assess. Where advice involves payment or a separate service agreement, address its terms and conflicts separately from equity ownership.

A simple responsibility matrix can be expressed in prose: founder A handles product and implementation; founder B handles sales and collections; the finance lead prepares reconciliations; the investor reviews indicators and participates in specified decisions. Address absences and substitutions too. Management remains responsible for execution and accurate reporting. Investor involvement does not certify the operation or reliably prevent loss. The memo should recognize the limits of oversight, especially where execution depends on a small number of people and replacing them would take time.

13

Record disagreements, conflicts and negotiated concessions

A well-documented decision does not require agreement on every assumption. A founder may expect implementation to become faster with experience, while the investor believes delivery still requires too much service work. Record both views, available evidence and the test that could distinguish them. If the disagreement affects price, explain how it influenced negotiation. A memo loses value when a harmonious account hides the concerns that nearly led to rejection or a different instrument.

Describe conflicts concretely. A participant might receive an intermediation fee, recommend a consultancy they partly own or invest in a competitor. Identify the relationship, its possible effect on analysis and the response adopted. Depending on the circumstances, independent assessment, restricted access or exclusion from a particular decision may be necessary. Disclosure alone does not resolve a conflict's consequences, but omission prevents others from properly evaluating the recommendation and alternatives.

Explain concessions as a package. A lower valuation may accompany additional rights; a higher valuation may be accepted with clearer information obligations. These terms are not interchangeable without limit: excessive veto rights can undermine management even at an appealing price. Record the relevant initial proposal, final package and reasons for acceptance. A single ownership percentage cannot capture deadlines, obligations, costs, exit conditions or effects on future hiring and rounds. The memo should make these trade-offs visible to everyone approving the transaction.

14

Test adverse scenarios before relying on them in negotiations

An adverse scenario should reveal decisions, rather than merely cut a forecast by a percentage. In the cash example, assume monthly receipts of R$ 10,000, R$ 12,000, R$ 15,000, R$ 18,000, R$ 20,000 and R$ 22,000 while keeping original outflows. Receipts total R$ 97,000. Starting with R$ 340,000 and spending R$ 360,000 leaves R$ 77,000. The month-three balance becomes R$ 207,000 instead of R$ 230,000. These figures alone do not establish insolvency, but reduce the margin for error and increase the urgency of responding.

Ask what explains the shortfall. Late collection under valid contracts requires a different response from cancellations because the product lacks usefulness. Slow implementation may call for simplification; costly acquisition may require revisiting the customer segment or offer. Identify spending that can be deferred, the time needed and the cost of doing so. Ending all sales activity might preserve immediate cash while damaging the next test. Link the response to the cause and the learning still worth financing.

Other scenarios include a founder leaving, an intellectual property dispute, loss of a dominant customer or an unavailable funding round. Identify exposure and possible responses without assigning artificial probabilities. Later investors may demand a lower valuation, increasing dilution, while existing holders may decline further funding. An equity interest may ultimately yield no capital recovery. Close monitoring, contractual protections and founder reputation cannot be treated as sufficient protection or as guarantees of repayment, liquidity or profitability.

15

Correct errors while preserving the decision history

Memos can contain transcription errors, poorly defined assumptions or conclusions weakened by new evidence. Distinguish incorrect information from a subsequent change. If a spreadsheet counted a sales proposal as collected cash, correct the fact, identify affected calculations and reassess the recommendation. If a customer later cancels a correctly recorded contract, record that as a new event. This distinction helps avoid concealing errors or retrospectively assuming the team knew something it could not yet have known.

A common mistake is dividing the investment by the pre-money valuation to calculate ownership. Here, R$ 300,000 divided by R$ 1,200,000 gives 25%, but the capital increase produces a 20% interest: R$ 300,000 divided by the R$ 1,500,000 post-money valuation. Other errors include adding convertible percentages without applying their formulas or omitting the team plan. Correct every version used for deliberation, including circulated summaries. Updating only the central spreadsheet leaves inconsistent figures in circulation.

Use version control recording the author, revision sequence, reason and effect on the decision. Superseded documents should remain recoverable under appropriate access controls and clearly marked as inactive. A material correction before disbursement requires reviewing authorization through the defined procedure. After investment, record its economic effect and the response taken. Historical integrity supports learning and fair accountability; it cannot justify retaining a conclusion contradicted by the facts. Readers should be able to reconstruct both the original reasoning and why it changed.

16

Keep documentation and intermediation within their proper boundaries

A project-based approach can use technology to organize objectives, stage, documents, funding needs and evidence of progress. This provides context for KEZS, which connects entrepreneurial projects and potential funders through technology and intermediation. Investors conduct their own due diligence and make their own decisions; KEZS does not assign a credit score. The potential usefulness of organized documentation lies in making questions and gaps easier to identify, without replacing analysis, professional advice or negotiation of transaction-specific terms.

Identify each participant's role and compensation in the proposed structure. Technology services, intermediation, public securities distribution and other financial activities are different functions. Public offerings and regulated activities require appropriate structures and providers; technology or a CNAE business activity classification is not permission to perform them. A company's participation in discussions does not establish banking partnerships, regulatory authorization or availability of a service. Verify the actual arrangement rather than inferring capabilities from institutional materials.

Transparency must respect confidentiality. Do not indiscriminately expose complete corporate documents, personal information or customer contracts, and do not place private documents on public blockchains. Technical integrity of a record does not establish factual truth, valid legal title, reserve solvency or guaranteed payment. Prioritize access controls, defined purposes and responsibility for information. Documentation and verification costs can consume a meaningful share of a small investment while leaving economic uncertainty unresolved. Any external references are research entry points, not proof of KEZS authorization.

17

Close with an executable decision and a review process

The memo should support three legitimate outcomes: invest, decline or defer for specific evidence. In the example, a recommendation could be R$ 300,000 in equity producing 20% immediately after investment, subject to corporate verification, formalization of negotiated rights and resolution of identified issues. Make clear that modeling a later team plan and funding round does not approve either. Each subsequent transaction requires the applicable documents and decision-making authority.

Record participants, the version reviewed, disclosed conflicts, outcome, reservations and conditions before disbursement. For each condition, identify the responsible person, required evidence and person authorized to confirm fulfillment. State where funds go, which formal documents are required and how checks occur before transfer. If deferring, name the uncertainty and event that would allow analysis to resume. Requesting more information without a defined question merely prolongs negotiation and increases costs for both sides.

After funding, compare actual cash, collections, retention, implementation effort and execution against the original hypotheses. Differences should prompt explanations and decisions, rather than only updated charts. Depending on rights and circumstances, the investor may maintain the thesis, invoke an agreed process, negotiate changes or decline further capital. The memo remains useful when it preserves the original reasoning and supports learning from events. Its contribution is better, more traceable choices; even a carefully investigated decision can produce a loss.

FAQ

Frequently asked questions.

How do the investment memo, contract and decision record differ?

The memo organizes analysis and supports a recommendation. The contract establishes the parties' rights and obligations under the applicable structure. The decision record documents deliberation on a particular proposal version. They should be consistent, but cannot replace one another. If the memo expects monthly reports while the final documents omit that right, do not assume the expectation became binding. Resolve discrepancies before execution and make sure conditional approval is not mistaken for confirmation that every condition has been fulfilled.

How much detail is appropriate when the business has few sales?

Focus on uncertainties capable of changing the decision. A small customer base makes it practical to examine individual contracts, collections, delivery work and prior relationships with founders. It does not justify pages of unsupported precision. A relatively concise memo can be sufficient if it presents evidence, gaps, conditions and review criteria. Limited history must remain an explicit limitation, rather than disappear behind market estimates or general team experience. Explain why each additional investigation would matter before spending time and money on it.

Does a convertible investment avoid valuation and dilution analysis?

No. It can defer part of the valuation decision, but its formulas already allocate economic effects. Discounts, valuation caps, other convertibles and team equity arrangements can alter the eventual holding. Model plausible scenarios and explain what happens if the expected conversion event never occurs. Until the relevant terms are defined, promising a specific ownership percentage may mislead. Also examine rights and obligations before conversion; the possibility of future equity does not answer what the parties can require from one another in the meantime.

What if founders operate as a MEI and offer an equity interest?

A MEI cannot admit equity partners while remaining a MEI. Record that incompatibility and condition the transaction on an appropriate business structure, with legal and accounting guidance. Check where contracts, code, trademarks, obligations and collections currently sit, because reorganization must address the relevant business elements. An informal ownership promise neither removes the restriction nor establishes that the assets will be available to the company receiving funds. Do not treat a proposed restructuring as complete until its required evidence has been checked.

Should an investor receive direct access to bank accounts and customer data?

Monitoring rights do not imply unrestricted access. Information should be sufficient to verify cash and performance, with exposure proportionate to the purpose. Reconciled reports, selected supporting records and additional checks may meet that need without disclosing an entire customer database. The design depends on risks, contracts and responsibilities. Specify confidentiality, authorized recipients and conflict management. Excessive access creates costs and risks too, especially where an investor holds interests in competing businesses. Reporting access should not be confused with authority to operate an account.

What if a milestone is missed but the founders offer a plausible explanation?

Compare the explanation with evidence and with the question the milestone was designed to answer. An exceptional implementation request may require a different response from cancellations caused by poor usefulness. Record the cause, impact on cash and the thesis, proposed action and next verification point. Follow agreed procedures for contractual consequences or conditional tranches. Revising a milestone may be rational, but requires a documented decision. A plausible explanation does not automatically satisfy the original condition or authorize a disbursement that remains subject to it.

Does a later round at a higher valuation prove the first investor earned a return?

No. It may provide another negotiated valuation reference, subject to that transaction's rights and conditions. The original investor may still have no buyer, no distributions and a diluted holding. Assessing a realized return requires examining cash actually received, relevant costs and any sale terms. Keep estimated appreciation, possible exit and received money separate. A later round guarantees none of them. Its headline valuation also cannot establish that the first investor's holding could be sold on equivalent terms or within a particular period.

Should a decision not to invest also be documented?

Yes. Record decisive reasons, evidence reviewed and conditions that could justify another assessment. A poor fit with the investor's focus, an unacceptable price and a documentation problem are different grounds for declining. Avoid presenting rejection as a definitive judgment about the company's future. The record preserves the reasoning, reduces contradictions and helps a renewed discussion identify what actually changed. It can also prevent unnecessary repetition of completed diligence while ensuring that an unresolved material issue is not forgotten.
