Startup Due Diligence Checklist for Angel Investors in India
Due diligence at the angel stage in India is different from what happens at Series A or beyond. You’re not auditing a fully formed company — you’re making a bet on a founder’s ability to figure out something difficult, with limited information, in a compressed timeframe.
The due diligence process that serves you best at the early stage is therefore less about verification (though some of that is important) and more about conviction — whether you have enough signal to believe in the founder, the market, and the specific hypothesis they’re testing.
After evaluating hundreds of early-stage startups at Delhi Angels, here’s the checklist I use. Not every item applies to every deal, but working through this systematically means I rarely miss something that matters.
Founder and Team
Does the founding team have genuine insight into the problem?
The critical question isn’t “have they worked in this industry?” but “do they understand something about this problem that others don’t?” This insight could come from domain experience, from customer research, or from a period of time spent living inside the problem. The test: can they articulate their insight in a way that changes how you think about the market?
Can the team execute without key hires?
Most seed-stage startups plan to hire critical functions after funding. This is legitimate — but evaluate the team on what it can do today. Can the founding team ship, sell, and figure out its own problems? Teams that are fundamentally stuck waiting for someone they haven’t hired yet are higher risk than teams that are moving despite gaps.
Is there a clear decision-maker?
In co-founder dynamics, ambiguity about who owns which decisions creates friction that compounds over time. The founding team doesn’t need to be hierarchical, but they need to have worked through how they make hard calls. Ask them to walk you through a recent disagreement and how they resolved it.
Have they worked together before?
Not a requirement, but a positive signal. Teams with a shared working history have usually already surfaced some of the friction points. First-time co-founder relationships can work, but they carry higher interpersonal risk.
Product and Traction
What’s the smallest version of this that’s been tested?
The most useful signal at the early stage isn’t revenue — it’s whether the founder has put something real in front of real customers and observed their behaviour. Even a rough prototype, a manual process, or a pilot with 10 users provides more information than a polished deck.
What do retention numbers look like?
This is the single metric I weight most heavily at the early stage. Acquisition tells you about marketing. Retention tells you about product-market fit. A startup with 50 users and 80% 30-day retention is a much stronger signal than one with 5,000 users and 20% retention.
Who are the customers and why did they choose this?
Ask for specific customer names and the stories behind them. How did the first customer come to use the product? What problem were they solving when they found it? Would they recommend it to someone they know? The specificity of these answers is a signal of the depth of the founder’s customer understanding.
What does the customer not like?
Founders who have a clear-eyed view of their product’s weaknesses — and have heard this directly from customers — are more credible than founders who present only positives. The complaints customers make often contain the most important information about where the product needs to go next.
Market and Competition
Who are the direct and indirect competitors?
“We have no competitors” is a red flag, not a positive signal. It means either the market doesn’t exist, or the founder hasn’t looked hard enough. What you want to hear is a considered view of the competitive landscape, an honest assessment of each player’s strengths, and a clear articulation of why this team’s approach is differentiated.
Is there a specific customer segment that’s underserved?
The best early-stage businesses don’t try to win the whole market — they find a beachhead where they have a structural advantage and go deep. What is the specific segment where this product is dramatically better than the alternatives?
What’s the distribution insight?
Building a good product in India is necessary but not sufficient. Distribution — how you reach customers at scale — is where many startups get stuck. Does the founder have a clear, specific theory of how they’ll grow beyond the initial cohort?
Business Model and Economics
What does the unit economics story look like in steady state?
You’re not expecting perfection at pre-seed — you’re looking for a credible path to a business that works at scale. Can the founder explain what the business looks like in 3-4 years, and does that model make sense given what you know about the market?
What is the current burn rate, and how long does it give them?
Simple and critical. Know how much runway exists, and whether the team has a plan for what happens at the end of it.
What specifically will the capital raised be used for?
The allocation of investment capital is a window into the founder’s judgment. Is the plan to hire, to build, to acquire customers, or some combination? Does the plan match the current bottleneck in the business? Founders who can explain exactly why they need each rupee tend to be better allocators of it.
Legal and Governance Basics
At the angel stage in India, full legal due diligence is usually disproportionate to deal size. But a few checks are always worth doing:
- Is the company properly incorporated? (Pvt Ltd registration, PAN, etc.)
- Are the co-founders’ equity splits documented in a founders’ agreement?
- Are there any IP ownership issues — is all code and IP owned by the company, not by individual founders or prior employers?
- Are there any existing obligations (investors, loans, advisors with equity) that aren’t reflected in the cap table presented?
These aren’t exotic checks — but they surface problems that are cheap to fix before investment and expensive after.
The Judgment Call
Due diligence at the angel stage ultimately ends in a judgment call that no checklist can make for you. The checklist removes the obvious blind spots. The decision itself requires an opinion on whether this founder, in this market, with this approach, has a meaningful probability of building something worth backing.
The investors who develop the best judgment over time are the ones who stay curious after the investment. They track what they got right and wrong, build hypotheses about what signals predicted outcomes, and update their framework accordingly. The checklist is a starting point. The edge comes from what you do with it over dozens of investments.
