Due diligence in startups is a kind of comprehensive audit that investors carry out before investing in an emerging company. It is a meticulous process of investigation and analysis of the company's entire situation: financial, legal, accounting, operational and strategic. The goal is to verify whether everything the startup has presented (information, numbers, documents) matches reality, identifying hidden risks, liabilities and opportunities before closing the investment.
This stage is fundamental in the startup world. Unlike traditional companies, startups usually have a short track record, lean structures, and may not have all their processes formalized. That is why investing without proper due diligence is risky. Without this verification, problems such as undeclared debts, pending legal matters, inconsistencies in the business model or flaws in intellectual property can go unnoticed. Imagine discovering, after investing, that there is a multimillion labor lawsuit against the company, or that the product's source code belongs to an outside developer.
Due diligence therefore works as a safety filter for both investors and entrepreneurs. For the investor, it brings transparency and confidence, making it possible to reach an informed decision based on hard data (and not just on enthusiasm or promises).
For the startup, successfully passing this audit validates the credibility of the business: it is like earning a "seal of quality" that increases the chances of the investment happening under the expected terms. In short, well-executed due diligence mitigates risks and aligns expectations, making it indispensable for safe investments in startups.
When does due diligence take place in startup investing?
In the startup investment cycle, due diligence usually takes place after the investor expresses interest and signs a term sheet (memorandum of understanding), but before the investment is made and the final investment agreement is signed. In other words, it is an intermediate stage: the investor is already excited about the startup and has negotiated the preliminary terms of the round, but makes closing the deal conditional on verifying that everything is in order with the company.
In venture capital and angel investor practice, this process is standard. After the term sheet, diligence begins: the investor (or fund) puts together a team to examine the startup in detail. This team may include lawyers, accountants, financial analysts and even technical specialists, depending on the nature of the business. External consulting firms are often hired for the audit, precisely to ensure impartiality and depth of analysis. In more advanced startups or larger investments, it is common to have specific due diligence workstreams (financial, legal, tax, technical, etc.), conducted by different professionals.
How long does it take? There is no fixed timeframe; it all depends on the size and complexity of the startup, as well as the depth of analysis the investor wants. On average, due diligence can last from a few weeks to a few months. Early-stage startups with simple operations may get through the review in 2 or 3 weeks, while companies in an expansion phase, with many contracts and data to review, may require 2 or 3 months of auditing. It is important for the entrepreneur to have this sense of timing, since the funding round will only be completed after due diligence is finished (and approved).
Who conducts the due diligence? Generally, the responsibility lies with the interested investor (after all, they are the one who wants to be sure about the investment). Many investment funds have standardized checklists and in-house teams for this. However, the startup needs to collaborate actively: providing documents, answering questions and clarifying any doubts. In some cases, especially on crowdfunding platforms or in acceleration programs, the intermediary organization (e.g., an equity crowdfunding platform or an accelerator) carries out the due diligence on behalf of the investors before offering the opportunity. Either way, the startup must be prepared to go through someone's "X-ray," whether an individual angel, a venture capital fund or a hired consulting firm.
What do investors analyze in a startup's due diligence?
During due diligence, the startup will be scrutinized from multiple angles. Practically everything that could affect the success or the risk of the business comes under the examiners' eye. Below, we list the main points analyzed; you can think of them as a checklist of what will be verified:
- Corporate and legal compliance: Review of the Articles of Association and their amendments, ownership structure (duly registered quotas/shares), shareholders' agreements (vesting, tag along/drag along clauses, options, etc.) and registration with the commercial registry. The investor wants to be certain that the company is properly formalized, that each partner's stake is clear, and that there are no legal loopholes. Example: checking whether all previous capital increases were registered and whether there are no "hidden" partners outside the articles.
- Financial and accounting situation: Analysis of the startup's financial statements (trial balances, income statement, cash flow), accounts payable and receivable, debts, loans and cost structure. The financial health is assessed: whether the books are up to date, whether revenues and expenses match what was presented to investors, and whether there is cash runway or dependence on new investments to survive. Example: the investor will check indicators such as profit margin, revenue growth and burn rate, and may request access to bank statements and loan agreements to verify the accuracy of the numbers.
- Tax and labor obligations: Review of compliance with taxes and labor matters. This includes checking whether the startup is current with federal, state and municipal taxes (issuing tax clearance certificates), whether the tax regime adopted is correct, and also inspecting labor liabilities. Items such as payroll, employee and contractor agreements (CLT employees, PJ contractors, interns), social security (INSS) and severance fund (FGTS) contributions, and any ongoing labor lawsuits are analyzed. Example: detecting whether the company hired many workers as PJ (independent contractors under a legal entity) when in fact they work as exclusive employees; this type of situation can lead to a future labor claim, something the investor wants to know in advance.
- Intellectual property and intangible assets: For innovative startups, intangible assets are precious. Due diligence verifies registered trademarks, patents, software source code, trade secrets and copyrights. The important thing is to confirm that the startup actually holds the rights to its creations. Example: checking whether internally developed software has rights assignment agreements from all the programmers involved, avoiding the risk of an outsourced developer claiming ownership over part of the code. Likewise, verifying that there are no infringements (for example, that the startup's brand does not infringe a third party's trademark, or that key technologies are patented in the company's name).
- Products, services and market: This is where the startup's business model and value proposition are assessed from a critical standpoint. Investors examine traction indicators: number of users or customers, growth rate, churn (customer loss rate), size of the addressable market and competition. They also analyze the sales and marketing strategy: customer acquisition channels, customer acquisition cost (CAC), sales strategies and market positioning. Example: the investor may request metrics reports (Google Analytics, internal dashboards) to validate that the reported growth is real and sustained, and not just a temporary spike. In addition, they will check whether the startup has a solid business plan and understands its direct competitors.
- Operational processes and compliance: Operational efficiency and governance are also on the agenda. This includes checking whether the startup has well-defined processes, internal policies (compliance, code of conduct, privacy policies, LGPD (Brazil's General Data Protection Law), etc.) and an organizational structure suited to growth. In specific sectors (fintechs, healthtechs, etc.), compliance with industry regulations is checked. Example: a fintech will need to demonstrate that it follows Central Bank rules (such as anti-money laundering), a healthtech will have to show compliance with the requirements of Anvisa (Brazil's health regulatory agency), and so on. The absence of minimum compliance, or operating outside the sector's legal framework, would be a major red flag for the investment.
- Contracts and strategic partners: All of the startup's relevant contracts come under scrutiny: contracts with key customers, suppliers, partnership agreements, commercial agreements, lease agreements (if applicable) and so on. The investor wants to identify clauses that could impact the business, such as exclusivity, non-compete, warranties, penalties or excessive dependence on a single customer or supplier. Example: if the startup has a major customer that accounts for 50% of revenue and that customer's contract allows termination at any time, this is a risk that needs to be known. Or if there is a partnership agreement that prevents the startup from operating in a certain channel, limiting its expansion, the investor will weigh that in the decision.
This list covers the basic pillars of startup due diligence. In short, the investor will check for every "skeleton in the closet": from legal problems to business weaknesses. But do not see this process merely as a hunt for mistakes; it also serves to confirm the strengths. Well-executed due diligence can show, for example, that the startup has a highly competent and united team, that it has a loyal customer base, or that it adopted excellent financial practices early on. All of this counts in your favor when the decision is made!
Tips for due diligence without surprises: what your startup can do right now
Knowing everything that will be analyzed, it is clear that preparation is key. Many startups lose investments not because the business was bad, but because they arrived at due diligence unprepared: messy documents, conflicting information, unpleasant last-minute surprises. The good news is that this scenario can be avoided. Check out these practical tips to prepare for due diligence and greatly increase your chances of success:
1. Keep your "house" in order (organized documentation): Starting now, get into the habit of organizing all of the company's documents and records. Set up a kind of data room (it can be a well-structured cloud folder) containing: articles of association and meeting minutes, balance sheets and financial statements, cash flow spreadsheets, contracts with customers and suppliers, trademark/patent registrations, proof of tax payments, clearance certificates, employee/intern agreements, internal policies, etc. When due diligence begins, you will probably receive a list of requested documents; if everything is already filed and up to date, you score points for speed and demonstrate professionalism. Organized documents also prevent errors: for example, make sure that balance sheets and income statements are properly closed (preferably validated by an accountant), and that every relevant contract is signed by the parties and in force.
2. Run a preventive internal audit: Do not wait for the investor to point out problems; get ahead of them! Carry out an internal due diligence on your own. Gather your management team and assess the main points yourselves: review the finances in detail looking for inconsistencies, ask your lawyer (or partner law firm) to audit the contracts and the startup's legal standing, check whether all taxes were paid correctly, whether there are pending registrations, whether payroll is correct, etc. This honest self-assessment will reveal flaws there is still time to fix. For example, you might discover that you forgot to formally register that capital increase made a year ago, something easily fixed before the external audit. Or notice that a certain arrangement with a supplier has no written contract; there is still time to formalize it. Keep in mind that it is better to find and solve the problems now than to let the investor find them first (in which case trust may be shaken or tough demands may follow).
3. Resolve pending issues and fix "red flags": After mapping the weak points in the internal audit, move on to corrective action. Regularize whatever is irregular: pending legal matters? Resolve them or at least have an action plan (e.g., file an appeal in that lawsuit or negotiate a settlement before it becomes a large liability). Overdue taxes? Set up an installment plan and obtain updated clearance certificates. Missing contracts? Get them formalized in writing. No patent for a critical technology? Consider filing the application. It will not always be possible to eliminate every risk, but showing that you identified and addressed the problems minimizes their impact. Investors understand that problems may exist, but they greatly value it when the founder shows proactivity and transparency in resolving them. When presenting your startup, you can even mention: "We identified and have already resolved X and Y, so this will not be an obstacle."
4. Get your team prepared and aligned: Due diligence is not just about paperwork; it also involves conversations and clarifications. Investors may request meetings with the heads of different areas (finance, legal, technology, etc.) to clear up questions or dig deeper into the analysis. So engage your team in the process: explain to partners and key employees that the company will go through this review, guide everyone to collaborate with transparency, and appoint points of contact for each topic. For example, your CTO may need to explain the product architecture to the investor's technical analyst; the head of finance will have to show how cash flow is controlled; legal will interact by providing legal documents. If everyone understands the importance of the investment and is motivated to help, the startup conveys a far more professional and united image. Avoid surprises such as a key employee being caught off guard and giving incorrect information; align the key information internally (always truthfully, of course).
5. Be transparent and do not withhold information: It may be tempting to "hide" that weak point in the hope that it will not be discovered, but this is a disastrous strategy. Remember: due diligence exists precisely to uncover everything. The best path is to be upfront about any problems, presenting them along with the solutions or mitigations you have already set in motion (as mentioned in item 3). Transparency builds trust. If the investor realizes you tried to cover something up, the negotiation can sour for good. Instead, earn respect by saying, for example: "We had a tax setback last year, but we have already negotiated with the tax authorities and set up an installment plan for the debt; here are the receipts." This shows maturity and reliability on your part. Remember the saying: "trust takes years to build and seconds to destroy"; in due diligence, that is taken seriously!
By following these tips, your startup will be much better prepared to face due diligence. Preparation reduces the stress of the process and speeds up its conclusion, which benefits both sides. Furthermore, an organized and diligent startup conveys the image of a mature company, even increasing its perceived value (valuation) in the eyes of the investor. After all, who wouldn't want to invest in a business that demonstrates control and professionalism?
Frequently asked questions about startup due diligence (FAQ)
When should a startup go through due diligence?
Generally, this happens before receiving an investment. After negotiating an investment (with an angel investor, venture capital fund or corporate venture arm), but before signing the final agreement, the startup goes through due diligence. In other situations, due diligence may also take place in the event of a merger or acquisition of the startup by another company, or even in periodic internal audits to assess the health of the business. In short: whenever there are new entrants in the cap table or significant deals involving the startup, there will likely be due diligence.
Who pays for and who performs the due diligence in practice?
In investments, due diligence is in the investor's interest, so the investor usually bears the costs (hiring lawyers, accountants, etc.) and leads the process. However, there are various models: some investors pass part of the cost on to the entrepreneur, or negotiate for the startup to cover expenses if the deal does not go forward, for example. There are also cases, such as crowdfunding platforms or acceleration programs, in which the platform itself performs the due diligence before presenting the startup to investors (acting as a filter). Regardless of who pays, the startup must collaborate closely, providing information and documents. In summary: the investor leads/coordinates the diligence (with their own team or trusted third parties), and the startup makes everything needed available.
What documents does a startup need to provide in due diligence?
The exact list may vary, but in general the startup will have to provide all relevant corporate, financial, legal and operational documents. This includes: articles of association and amendments, cap table (updated ownership structure), financial statements (balance sheets, income statement, cash flow) for recent years, bank statements, accounting books, tax and labor clearance certificates, contracts with main customers and suppliers, employment or service agreements, trademark and patent registrations, confidentiality or non-compete agreements, business plans, user/customer metrics reports, and any other sector-specific documents (for example, Anvisa authorization if it is a healthtech). In short, everything that proves the startup's current and historical situation. It is highly recommended to put together a checklist/organized documents in advance to speed things up when requested.
How long does startup due diligence take?
The time can vary quite a bit. On average, complete due diligence takes between 30 and 60 days for small/medium-sized startups. Very early startups, with less data to analyze, can get through the process in a few weeks. On the other hand, if the company already has many contracts, different products or complex operations, diligence can stretch to 2 to 3 months. The timeline depends on factors such as: the amount of information to review, how quickly the startup responds in providing data, the depth of analysis the investor wants, and even the scheduling of third parties involved (for example, external auditors, law firms). To avoid delays, the tip is: have everything ready and respond quickly to requests; that way the process flows in the shortest time possible.
What happens if due diligence uncovers serious problems?
In that case, several things can happen. The ideal scenario is not finding any serious problems, but if significant red flags emerge, the investor will have to reassess the investment. The possibilities include:
- Renegotiation of terms: The investor may demand changes to the investment conditions. Example: lowering the startup's valuation to offset an identified risk, asking for a larger stake, or imposing protective clauses in the agreement (such as warranties or adjustments if the problem generates future costs).
- Remediation requirements: The investor may make the investment conditional on resolving the problem. For example, paying off a specific debt, removing a problematic partner or settling a dispute before completing the investment.
- Cancellation of the investment: In cases of very serious problems or loss of trust, the investor may simply walk away from the deal. Unfortunately, this happens; if due diligence reveals that the company was not viable or concealed information, the investment is unlikely to move forward.
For the startup, the best stance is to get ahead of the issues (as we saw in the preparation section) to avoid reaching this point. And if something is detected anyway, negotiate with transparency. Many investors are willing to adjust the deal as long as they see good faith and commitment from the entrepreneur to resolve whatever is possible.
Are due diligence and an audit the same thing?
Not exactly, although they are similar processes. A traditional audit is usually a formal examination, often mandatory, to verify whether the company is following standards (accounting, tax, etc.); for example, annual audits at large companies to certify financial statements, or specific quality audits. Due diligence, on the other hand, is an investigation aimed at a negotiation or decision. In other words, due diligence has a specific purpose: to provide input for a transaction (investment, acquisition, partnership). It is more comprehensive and flexible, according to the investor's interest, and may include strategic analyses that a conventional audit does not perform. In addition, audits tend to be periodic and internal, while due diligence is one-off and performed by an outsider (a potential investor or buyer). In short: all due diligence is a form of pre-deal audit, but not every audit is due diligence. And for startups, due diligence is crucial in an investment, while regular internal audits may not even exist in the first years of life (but should come into place as the company grows).
Do investors look at ESG or sustainability aspects in due diligence?
Increasingly, yes. ESG (environmental, social and governance) criteria have been gaining relevance in investments. Although the bulk of startup due diligence is financial and legal, many investors, especially larger or corporate funds, include ESG and ethical compliance checks. This may mean verifying diversity and inclusion policies at the startup, environmental practices (for example, proper waste disposal if it is a manufacturing business, or carbon footprint in tech), and corporate governance (boards, transparency). If the fund has public sustainability commitments, it will certainly assess these points before investing. So it is worthwhile for the startup to show that, even while young, it cares about good environmental and social practices and has an ethical organizational culture. This may not be as decisive as the financial numbers, but it earns positive points and prevents obstacles if the investor has strict filters in this regard.
Due diligence
Facing due diligence can seem intimidating for any startup founder; after all, it is like placing your company under a powerful magnifying glass. But remember: this stage exists to protect both parties and enable healthy investments. If your startup is well prepared and you adopt a transparent stance, due diligence stops being a monster and even becomes an opportunity to learn about your own business (many entrepreneurs report that, by gathering documents and analyzing everything, they gained valuable insights).
In short, prepare, stay calm and collaborate throughout the process. We have covered what is examined and several tips on how to prepare; put them into practice as soon as possible. That way, when that dream investor shows up ready to bet on your startup, you will be ready to pass the "test" with flying colors and receive the investment that takes your business to the next level.
