Due Diligence Guide for Founders

Your Diligence Process is a Product, Not a Chore

Investor due diligence isn't a test you passively take; it's a process you actively manage. It begins the moment you get a term sheet and typically lasts 2-4 grueling weeks. The investor's goal is simple: verify your claims and uncover any hidden risks. Your goal is to make this process boringly clean.

A fast, organized, and transparent diligence process signals that you run a fast, organized, and transparent company. A slow, sloppy process is the biggest red flag of all. It makes investors wonder what else is a mess. This guide will show you how to run a bulletproof process that builds momentum and gets you to the close.

First, Diligence Your Investors

Before an investor digs into your business, you must dig into theirs. Taking a check is a 10-year marriage. A bad partner is worse than no partner. Once you have a term sheet, you have earned the right to conduct “reverse diligence.”

Your goal is to understand how a VC behaves when things go wrong. The star founders in their portfolio will always be happy. You need to talk to the founders of companies that struggled, pivoted, or died. That’s where you’ll find the truth.

How to Ask for References

Don't be shy. Send a direct email to the partner leading your deal. Here's a script:

Excited about the prospect of working together. As a next step, could you connect me with 2-3 founders you've backed? I'd love to learn more about their experience with the firm.

Ideally, I'd appreciate a mix—perhaps someone who's had a huge outcome, but also someone who's had to navigate a tough patch or a pivot. Understanding how you partner with founders in challenging moments is really important to us.

Questions to Ask a VC's References

When you get on the phone with a founder, go beyond the basics. These questions will get you the real story:

The Support Question: "Beyond the money, what is the single most helpful thing [Partner Name] has done for you? Give me a specific story." (Vague answers like "they're a great sounding board" are a yellow flag). · The Crisis Question: "Tell me about a time you almost failed or missed a plan badly. How did the partner and the firm react? Did they get in the trenches with you, or did they create more pressure?" · The Next Round Question: "When it was time to raise your next round, how exactly did they help? Did they provide a warm intro to the partner who led the deal? How many intros did they make in total?" · The Surprise Question: "What’s one thing that surprised you—good or bad—about working with this firm? What do you know now that you wish you knew when you took their money?" · The 'Would You Do It Again' Question: "Knowing everything you know now, would you take money from this firm again?" (Listen for the pause).

Building Your Data Room: The Foundation of a Smooth Process

Your virtual data room (VDR) is the single source of truth for your company. It’s where investors and their lawyers access every document related to your business. Don't wait for a term sheet to start building it. A pre-built data room lets you grant access instantly, signaling you’re a pro.

Use a service like Google Drive, Dropbox, or a dedicated VDR platform. The structure should be simple and predictable. Don't get creative. Use this folder structure:

01Corporate · 02Financials · 03Commercial · 04ProductandIP · 05Team · 06Fundraising

01. Corporate Diligence: The Legal Plumbing

This section confirms your company is a real, properly-formed entity. Messiness here is a huge red flag and can require expensive legal cleanup, often in the $5,000 to $25,000 range.

Formation Docs: Certificate of Incorporation, Bylaws, and any amendments. · Board Consents: Minutes and written consents for every major company decision (e.g., stock issuances, financings, director appointments). Every share you've ever issued needs a corresponding board approval. · Cap Table: A complete, up-to-date capitalization table. This is the single most scrutinized document in diligence. It must list every security holder (founders, employees, advisors, investors) and every type of security (common stock, preferred stock, options, SAFEs, notes). Double-check that the fully-diluted share count is 100% accurate. · Securities Docs: Copies of every signed agreement related to equity, such as Stock Purchase Agreements, SAFE notes, convertible notes, and option grant agreements. · Founder Stock Docs: Founder stock purchase agreements and, critically, proof of 83(b) elections if founders purchased stock subject to vesting. A missing 83(b) filing can create a massive personal tax liability.

02. Financial Diligence: Verifying the Numbers

Here, investors confirm your financial health and the viability of your business model.

Historical Financials: Profit & Loss, Balance Sheet, and Cash Flow statements for the last 1-3 years (or since inception). These should ideally be accrual-based and GAAP-compliant, but if not, be prepared to explain your accounting methods. · Financial Model: The full operating model for your 3-5 year projections. Be ready to defend every assumption, especially your inputs for customer acquisition cost (CAC), lifetime value (LTV), churn, and sales cycles. · Bank Statements: The last 12 months of statements to verify cash balances. · Tax Filings: All federal, state, and local tax returns filed since incorporation.

03. Commercial Diligence: Your Business Relationships

This covers your relationships with customers and suppliers. The goal is to identify dependencies and risks.

Customer Contracts: Any non-standard or large customer agreements. You must highlight any contracts with revenue concentration (e.g., a single customer representing >20% of your revenue). · Vendor Agreements: Major supplier, manufacturing, or partnership agreements. Investors look for risks like short-term expirations or lack of exclusivity for critical components. · Sales Pipeline: An overview of your current sales pipeline and a brief summary of your sales process and strategy. · Litigation: You must disclose any pending, threatened, or past legal disputes. Hiding this is an instant deal-breaker.

04. Product, Tech & IP Diligence: What You've Built

Investors need to verify that you own the intellectual property core to your business.

IP Assignment (PIIAs): This is non-negotiable. You need a signed Proprietary Information and Invention Assignment (PIIA) agreement from every single person who has ever written code or contributed to the product. This includes co-founders, employees, interns, and freelance contractors. A missing PIIA means someone could legally claim ownership of part of your product, which can kill a deal on the spot. · Patents and Trademarks: A list of all filed or granted patents, trademarks, and registered copyrights. · Open Source Software: A description of the open-source software (OSS) used in your product and your policy for managing it. Certain OSS licenses (e.g., GPL) can require you to make your own proprietary code public. Run an OSS scan to ensure you have no license conflicts. · Tech Stack: A high-level overview of your technology architecture and your product roadmap.

05. Team Diligence: Who is Building It

The final pillar is your team. This section formalizes who works for you and how.

Team Roster: A list of all current employees and key contractors, with their role, salary, equity holdings, and start date. · Template Agreements: Your standard offer letter, consulting agreement, and any employee handbook. · Benefits Summary: An overview of employee benefits like health insurance and 401(k) plans. · Background Checks: Be prepared for the lead investor to run formal background checks on all founders. Be upfront about anything they might find—a past misdemeanor, a personal bankruptcy. Disclosing it yourself is manageable; them finding it is a breach of trust.

The 5 Most Common Deal-Killing Mistakes

Surprises. The #1 rule of diligence is no surprises. An undisclosed lawsuit, a key metric that's wrong, a founder who didn't actually graduate from the university on their bio—these things kill deals not because of the issue itself, but because of the deception. · A Messy Cap Table. Undocumented verbal equity promises, conflicting SAFE terms, or incorrect share counts will halt a deal. Your cap table must be a perfect, auditable record. · Missing IP Assignments. If a co-founder or early contractor leaves without signing a PIIA, you don't fully own your code. This is a five-alarm fire. Fix it before you even think about fundraising. · Customer Concentration Risk. If 70% of your revenue comes from a single customer on a 90-day contract, that's a huge risk. Be ready to explain your plan to diversify revenue. · A Slow, Disorganized Process. Taking a week to answer a simple data request signals chaos. It erodes confidence and gives investors cold feet. A slow process is a suspicious process.

Managing the Process Like a Pro

How you manage diligence reflects how you manage your company. Follow these rules to build trust and momentum.

Appoint a Quarterback. Designate one person (usually the CEO) as the single point of contact for all requests. All communication should flow through them to avoid conflicting answers. · Create a Diligence Tracker. Use a simple Google Sheet with columns for: Request #, Request, Requesting Party, Status (In Progress, Complete), and a Link to the document. This keeps everyone on the same page and holds you accountable. · Respond with Speed. Acknowledge every request within hours. Aim to fulfill requests within 24 hours. If it will take longer, communicate a clear timeline. Speed kills doubt. · Disclose, Don't Hide. If you know there's a problem—a small tax lien, a past employee dispute—tell your lead investor proactively. Frame the issue, explain how you've contained it, and present it as a solved problem. They will find it. Getting ahead of it shows you are trustworthy.
