The Seed VC Due Diligence Checklist: 10 Things to Verify Before Writing a Check

At seed stage, you're betting on potential — not revenue. That makes due diligence harder, not easier. Here's the framework experienced seed investors actually use to evaluate deals before committing capital.

Why Seed-Stage Due Diligence Is Different

Growth-stage due diligence is spreadsheet work. You have revenue, margins, churn, cohort data. You can model scenarios and stress-test assumptions with real numbers.

At seed, you have almost none of that. Maybe there's some early traction — a few hundred users, some pilot revenue. But you're fundamentally evaluating a team, an idea, and a market, not a business. The company might be 3 months old. The product might be an MVP. The "financials" might be a Google Sheet with optimistic projections.

This doesn't mean you skip due diligence. It means you need a different framework — one designed for the information environment you're actually working in.

"The biggest mistake new seed investors make is either over-diligencing (treating it like a Series B) or under-diligencing (writing checks based on vibes). You need a lightweight but rigorous framework."

— Common advice in seed VC circles

The checklist below covers the 10 areas that matter most at seed. For each one, we include the key questions to answer and red flags to watch for. The goal is to be thorough without being slow — most seed rounds close in 2-4 weeks, and you can't afford a 6-week diligence process.

The 10-Point Checklist

1 — Team Assessment

Who are the founders, and why them?

At seed, the team IS the investment. The product will change. The market positioning will evolve. The team is the constant. You need to answer two questions: Can these people build this? And will they stick with it when things get hard?

Key questions:

2 — Market Sizing

Is the market big enough to matter?

You don't need a $50B TAM slide. What you need is conviction that this market can support a venture-scale outcome. A $500M addressable market with strong tailwinds and a clear wedge is often better than a vague "trillion dollar market" claim.

Key questions:

3 — Product-Market Fit Signals

Is there any evidence people want this?

At seed, you won't have product-market fit. But you should see signals. Waitlist signups. Users who found the product organically. Someone who's paying even though it barely works. Any indication that this solves a real, urgent problem — not just an interesting idea.

Key questions:

4 — Cap Table Review

Is the ownership structure clean?

A messy cap table at seed is a preview of future problems. You're looking for a clean structure with founders holding enough equity to stay motivated through multiple rounds. Red flags: too many investors already, unusual preference stacks, or a founder who's already diluted below 50%.

Key questions:

5 — Reference Checks

What do people who've worked with the founders say?

This is the most underrated part of seed diligence. Back-channel references — not the curated list the founder gives you — reveal patterns that no pitch deck can hide. Talk to former colleagues, co-founders, employees, and other investors who passed.

Key questions:

6 — Competitive Landscape

Who else is solving this problem?

Every market has competition. If the founder says "we have no competitors," they either haven't looked or don't understand the market. What you want to understand is the competitive dynamics: why does this team's approach win, and what would make it hard for others to catch up?

Key questions:

7 — Unit Economics

Can this business make money?

You won't have polished unit economics at seed. But you should understand the business model logic: how will this company make money, what's the expected price point, and does the math work at scale? A back-of-napkin LTV/CAC estimate is more useful than a 50-tab financial model.

Key questions:

8 — Legal & IP

Are there hidden landmines?

Seed-stage legal diligence isn't about hiring a law firm for six weeks. It's a quick scan for obvious risks: IP assignment, non-competes, pending litigation, or regulatory issues that could kill the business. Five focused questions can surface most problems.

Key questions:

9 — Customer Interviews

Do real users validate the founder's claims?

Talk to 3-5 actual users or customers. Not the testimonials on the website — real conversations. You're looking for two things: does the product solve a genuine pain point, and would these customers be devastated if it disappeared tomorrow? If the answer to the second question is "meh," that's a signal.

Key questions:

10 — Deal Terms

Are the terms fair for this stage?

The best company in the world is a bad investment at the wrong price. At seed, you're typically looking at SAFEs or priced rounds with valuations between $5M-$20M pre-money (in 2026). Make sure the terms are market-standard and the valuation gives you enough ownership to justify the risk.

The Step Before Due Diligence: Finding the Right Deals

This checklist helps you evaluate companies once they're in your pipeline. But the hardest part of seed investing isn't diligence — it's finding the deals worth diligencing in the first place.

Most seed VCs spend 15+ hours per week on manual deal sourcing — scrolling Twitter, checking Product Hunt, monitoring fundraising announcements. By the time a deal reaches your inbox through a warm intro, three other funds have already had first meetings.

That's why we built DealPulse. It automates the sourcing step entirely — monitoring Product Hunt, Hacker News, and the entire startup ecosystem 24/7, scoring every company against your investment thesis, and delivering a prioritized deal feed every morning. You spend 20 minutes reviewing instead of 15 hours sourcing.

If you're evaluating your current deal sourcing toolstack, we also wrote a detailed comparison of the best Affinity CRM alternatives for seed VCs to help you pick the right CRM once deals are in your pipeline.

Making It Practical

The biggest risk with any checklist is turning it into a bureaucratic process. At seed, you don't have time for that. Here's how to use this framework efficiently:

The best seed investors move fast AND make good decisions. Speed doesn't mean skipping diligence — it means having a system that lets you cover the critical areas without wasting time on irrelevant analysis. This checklist is that system.

Find deals worth diligencing

DealPulse monitors the startup ecosystem 24/7 and scores companies against your investment thesis. Spend less time sourcing, more time on the deals that matter.
