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
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:
- Do the founders have relevant domain expertise or technical skill?
- Have they worked together before? How did they meet?
- What's the equity split? (Equal or near-equal is a green flag.)
- Are they full-time? What's their personal runway?
- Have they built anything before — shipped products, managed teams, sold to this buyer?
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:
- What's the realistic addressable market in 3-5 years?
- Is the market growing? What's driving that growth?
- Can you identify at least 1,000 potential customers who would pay for this?
- Is this a market where a startup can win, or is it dominated by incumbents with insurmountable distribution?
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:
- How many users/customers are there? How did they find the product?
- What's the retention look like for early users?
- Have any customers offered to pay before being asked?
- Can the founders articulate why users come back (or don't)?
- Is there organic growth or word-of-mouth happening?
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:
- What does the current cap table look like? Who owns what?
- Are there existing investors with unusual rights or preferences?
- Is the option pool sized appropriately (10-15% is standard)?
- Are there any outstanding SAFEs or convertible notes? At what terms?
- Will founders still have meaningful ownership after this round?
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:
- What's the founder like to work with under pressure?
- Do they listen to feedback or are they dogmatic?
- Have they ever quit something? Why?
- Would this person's former colleagues work with them again?
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:
- Who are the direct and indirect competitors?
- What's the founder's honest assessment of competitive advantages?
- Is there a defensibility moat forming (data, network effects, switching costs)?
- Are well-funded incumbents likely to build this as a feature?
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:
- What's the pricing model? Is there validation customers will pay that price?
- What are the primary cost drivers (engineering, sales, infrastructure)?
- At 1,000 customers, what does the margin structure look like?
- Is this a high-margin software business or something with structural cost challenges?
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:
- Has all IP been properly assigned to the company (not the founders personally)?
- Are any founders subject to non-compete agreements from prior employers?
- Is the company incorporated properly (Delaware C-corp is standard for US VC)?
- Are there any pending or threatened legal actions?
- Does the product operate in a regulated industry? What's the compliance landscape?
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:
- How did you find this product?
- What were you doing before you started using it?
- What would you do if this product disappeared tomorrow?
- Have you recommended it to anyone? Would you?
- What's the biggest thing you wish it did better?
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.
Key questions:
- What's the pre-money valuation? Is it justified by traction and market?
- SAFE or priced round? If SAFE, what's the cap and discount?
- How much are they raising? Does the use of funds make sense for 12-18 months of runway?
- What milestones are they targeting before the next raise?
- Do you have pro-rata rights for follow-on?
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:
- Parallelize: Run reference checks, customer interviews, and legal review simultaneously, not sequentially. You can cover all 10 areas in 5-7 business days.
- Calibrate to conviction: If the team and market are exceptional, you can move faster on the other items. If something feels off, dig deeper there specifically.
- Document as you go: Write a 1-page investment memo after completing the checklist. It forces clarity and gives your future self context when the company comes back for a Series A.
- Know your dealbreakers: Not every red flag is a dealbreaker. Decide in advance which items are non-negotiable (e.g., IP assignment, founder full-time commitment) vs. which are risks you can price in.
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.
