Investor Due Diligence Checklist: How to Prepare Your Startup for Investor Scrutiny

You’ve nailed the pitch. The investor is interested. Now comes due diligence — the process where investors verify every claim you’ve made about your startup before committing capital. 90% of deals that fall apart do so during due diligence because founders weren’t prepared. Don’t let that be you.

At Swyft Fundr, we’ve guided dozens of startups through the due diligence process. Here’s the complete checklist of what investors will ask for — and how to have it ready before they even ask.

Corporate Documents: Your Startup’s Legal Foundation

Investors will want to see that your startup is properly structured and that there are no corporate governance issues that could create problems later:

• Certificate of Incorporation — properly filed in Delaware (or your state of incorporation)
• Bylaws — your company’s operating rules and governance structure
• Cap Table — fully diluted, showing all equity holders, SAFEs, convertible notes, and option pool
• Board Resolutions and Meeting Minutes — evidence of proper corporate governance
• Stockholder Agreements — any agreements between existing shareholders

Financial Documents: Prove Your Numbers Are Real

Your financial due diligence package should paint a clear picture of your startup’s financial health and trajectory. Investors will cross-reference these documents against the claims in your pitch deck:

1. 1Monthly financial statements — P&L, balance sheet, and cash flow for the last 12–24 months
2. 2Bank statements — verifying your reported cash position and burn rate
3. 3Revenue documentation — contracts, invoices, and proof of recurring revenue (MRR/ARR)
4. 4Financial model — your 3-year projections with clearly documented assumptions
5. 5Tax returns — last 2 years of federal and state returns

Intellectual Property: Protecting Your Startup’s Core Value

For technology startups, IP due diligence can make or break a deal. Investors need confidence that your startup actually owns the technology it’s built:

• Patent filings and registrations — any provisional or granted patents
• Trademark registrations — your company name, product names, and logos
• Employee IP assignment agreements — CRITICAL: ensures all code and inventions are owned by the company, not individual engineers
• Open source usage audit — documentation of all open source libraries used and their licenses
• Prior inventions disclosure — any technology that founders brought to the company from previous roles

IP Red Flag for Investors

If your engineers don’t have signed IP assignment agreements, investors will pause the entire deal. This is non-negotiable — get these signed before you start fundraising. It takes 10 minutes per person and prevents months of legal complications during due diligence.

Team and HR Due Diligence

Investors invest in teams, not just products. They’ll want to understand your team’s background, compensation, and any potential HR risks:

• Founder backgrounds and references — LinkedIn profiles, prior company track records, domain expertise
• Employment agreements — for all key team members, including non-compete and confidentiality clauses
• Equity vesting schedules — all founders should be on 4-year vesting with 1-year cliff
• Key person dependencies — investors assess ‘bus factor’ risk on critical roles

Legal and Regulatory Due Diligence

Any legal issues — current or potential — need to be disclosed and documented. Surprises during due diligence kill deals:

• Pending or threatened litigation — any current or anticipated legal disputes
• Regulatory compliance — especially for fintech, healthtech, or data-heavy startups
• Data privacy compliance — GDPR, CCPA, SOC 2 readiness
• Material contracts — customer agreements, vendor contracts, partnership agreements

How to Organize Your Due Diligence Data Room

Set up a virtual data room (Google Drive, Notion, or a dedicated platform like Carta or DocSend) with clearly labeled folders matching the categories above. Share access when investors request it — having everything organized and ready signals professionalism and accelerates your fundraising timeline.
