Startup Due Diligence: What Investors Check and How to Prepare

The moment an investor says "we're interested — can you share your data room?" is not when you should start building your data room.

Most deals that stall or die in due diligence do so because of problems that were foreseeable and preventable. The founders who close quickly are the ones who treat due diligence preparation as an ongoing responsibility, not a fundraising task.

What investors are checking, and why

Due diligence is not about finding reasons to say no. It's about confirming that what you've said matches reality, and identifying any risks that need to be priced in or mitigated before closing.

The three areas of diligence:

1. Business diligence — Does the business do what the founders say it does? This includes customer reference calls, product walkthroughs, market analysis, and competitive landscape.

2. Financial diligence — Are the numbers real and clean? This includes financial statements, revenue recognition, burn rate, and cap table accuracy.

3. Legal diligence — Is the company properly structured and clean of legal risk? This is the area that most often surfaces deal-killing surprises.

The standard data room documents

Organize these into a shared folder (Google Drive or a proper data room tool like Notion or DocSend) before you begin your process:

Corporate structure:

• Certificate of Incorporation
• Memorandum and Articles of Association
• All board and shareholder resolutions
• Register of Members (complete, current cap table)

Cap table:

• Current cap table with all instruments (equity, SAFEs, convertible notes, option pool)
• All historical share issuances at what price and to whom
• ESOP plan document and grant summary

Financial documents:

• Last 2 years of P&L, balance sheet, cash flow (audited if available)
• Current financial model with assumptions clearly labeled
• Bank statements for last 6 months
• All existing debt facilities or liabilities

Legal and compliance:

• All founder employment agreements or consultant agreements
• IP assignment agreements for all founders and early employees
• All material contracts (customer agreements, vendor agreements, leases)
• Any litigation or legal dispute history (be proactive — investors will find it)
• Regulatory licenses or filings relevant to your business

People:

• Org chart
• Key employee offer letters
• ESOP grants outstanding

Product:

• Product demo video or product access for investors
• Key product metrics (retention, engagement, active users)

The documents that most often surface problems

IP assignment: if your founders or early employees don't have clear IP assignment agreements, the ownership of the core product is ambiguous. This is a genuine deal-killer and takes weeks to fix.

Cap table cleanliness: missing shareholders, incorrect ownership percentages, or undocumented previous share issuances confuse investors and require legal remediation.

Customer contracts: if your key customers are on informal purchase orders or handshake agreements, investors will require proper contracts before closing.

Regulatory compliance: FEMA compliance for foreign investment, GST filings, TDS compliance — clean on paper or clean up before you raise.

The due diligence approach that works

Pre-build your data room. Have everything organized before you start your process. When an interested investor asks for documents, you can share a complete, organized folder immediately. This signals professionalism and speeds the process by 2–3 weeks.

Disclose proactively. If there's a known issue — a legal dispute, a co-founder who left badly, a regulatory gap — bring it up before investors find it. How you handle a known problem matters more than the problem itself.

Use a startup lawyer. The CA who handles your GST filings is not equipped to clean up a cap table or fix an IP assignment agreement. Spend the Rs 50,000–1,00,000 on a startup-specialized lawyer before you raise. It will pay for itself many times over.
