The Complete VC Due Diligence Checklist for Founders
You have pitched well, the partner is excited, and a term sheet feels close. Then comes due diligence, the phase where deals quietly die. Most founders think of diligence as a formality. It is not. It is the phase where investors validate every claim you have made and look for reasons to say no. Here is exactly what they check and how to prepare.
What Due Diligence Actually Looks Like
Due diligence typically begins after a verbal commitment or signed term sheet but before the money hits your bank account. It can take anywhere from two weeks for a seed round to eight weeks or more for a Series B and beyond. The process involves a combination of document review, customer and reference calls, technical evaluation, and legal analysis.
The VC's goal is straightforward. They want to confirm that the business is what you represented it to be and that there are no hidden risks that would change their investment decision.
The Financial Diligence Checklist
Revenue and unit economics. Expect VCs to scrutinize your revenue numbers line by line. They will want to see monthly revenue broken down by customer, cohort retention curves, gross margins by product line, and the trajectory of your unit economics over time. If you are pre-revenue, they will focus on burn rate, runway, and the assumptions behind your financial model.
Cap table and previous funding. Your cap table must be clean and current. VCs will verify every previous round, every SAFE and convertible note, every option grant, and every advisor share. Messy cap tables with unclear ownership, missing documents, or unresolved conversion terms are one of the most common dealbreakers.
Financial projections. VCs do not expect your projections to be accurate. They do expect them to be internally consistent and grounded in defensible assumptions. Build your model bottom-up from real inputs like current pipeline, conversion rates, and average contract values rather than top-down from market size.
Bank statements and accounting. Later-stage rounds will involve a review of your actual bank statements, QuickBooks or equivalent records, and potentially a quality of earnings analysis. Make sure your reported numbers match your actual accounting.
The Legal Diligence Checklist
Corporate formation and governance. Your certificate of incorporation, bylaws, and all board and stockholder consents should be organized and accessible. VCs will verify that the company is properly incorporated, usually as a Delaware C-corp for US companies.
IP ownership and assignments. Every person who has ever written code or created IP for the company should have a signed invention assignment agreement. This includes cofounders, early employees, and especially contractors. Missing IP assignments can kill a deal outright.
Material contracts. Be prepared to share your key customer contracts, vendor agreements, partnership deals, and any exclusivity arrangements. VCs are looking for concentration risk, unfavorable terms, and change-of-control provisions.
Employment and contractor agreements. All employees should have offer letters, at-will employment agreements, and confidentiality agreements on file. Contractors should have clear work-for-hire provisions. Misclassification of contractors as employees is a growing area of scrutiny.
Pending or threatened litigation. Disclose everything. A lawsuit you fail to mention that surfaces later will destroy trust and likely kill the deal, even if the lawsuit itself is immaterial.
The Product and Technical Diligence Checklist
Technical architecture review. For larger rounds, some VCs will bring in a technical advisor or CTO-in-residence to evaluate your codebase, infrastructure, and technical debt. They are looking for scalability risks, security vulnerabilities, and whether your architecture can support your growth plan.
Product roadmap and competitive positioning. Be prepared to walk through your product roadmap in detail and explain how you are differentiated from competitors. VCs will do their own competitive analysis, so do not try to minimize the competition.
Data and privacy compliance. If you handle personal data, expect questions about your compliance with GDPR, CCPA, and other applicable regulations. Having a clear data privacy policy and documented compliance procedures is increasingly table stakes.
The Market Diligence Checklist
Customer references. VCs will want to speak directly with three to five of your customers. They will ask about the sales process, implementation experience, product value, and likelihood of renewal or expansion. Coach your customers on what to expect, but never script their answers.
Market sizing. Your TAM, SAM, and SOM should be defensible and sourced. VCs prefer bottom-up market sizing over top-down analyst reports. Show them how you calculated your numbers from real data rather than quoting a Gartner report.
Competitive landscape. Prepare an honest competitive analysis that acknowledges where competitors are strong, not just where they are weak. VCs respect founders who demonstrate clear-eyed awareness of their market.
The Team Diligence Checklist
Founder background checks. VCs will verify your employment history, educational credentials, and sometimes run formal background checks. Be honest about your background on your LinkedIn profile and in conversations.
Reference calls on founders. Expect VCs to contact former colleagues, managers, and cofounders. These calls are among the most influential parts of the diligence process. Identify three to five strong references in advance and give them a heads-up.
Key person risk. VCs will assess how dependent the company is on any single individual. If only one person understands your architecture or only one person owns customer relationships, that is a risk you should have a plan to mitigate.
Common Dealbreakers
These are the issues that most frequently kill deals during diligence:
- Misrepresented metrics. Inflating revenue, overstating growth rates, or mischaracterizing customer relationships. If a VC catches a single material misrepresentation, the deal is dead.
- Unresolved cofounder disputes. Active or simmering cofounder conflicts, especially around equity splits, signal instability.
- Missing IP assignments. If a departed cofounder or early contractor never signed an IP assignment, the VC's lawyers will flag this immediately.
- Customer concentration. If more than 30 to 40 percent of your revenue comes from a single customer, expect hard questions about diversification.
- Regulatory exposure. Operating in a gray area without legal counsel or a clear compliance strategy is a red flag at any stage.
How to Prepare Before You Start Fundraising
The best time to prepare for diligence is before you start fundraising. Create a virtual data room and organize it into clear sections: corporate documents, financials, legal agreements, product documentation, and team information. Keep it current. Having a clean data room ready on day one signals professionalism and dramatically speeds up the process.
Use VCPeer to research how thorough different VCs are during diligence. Some firms have notoriously intensive processes. Knowing what to expect helps you prepare the right materials in advance and avoid scrambling during the most critical phase of your fundraise.
