Reading guide

Paradigm partner Casey Caruso’s early-stage due diligence checklist starts with founders: the team is the constant in the early-stage equation, so ask whether you would work with this person. Next, assess the opportunity’s size and think ambitiously about the market. Always use the product yourself—a frequently skipped step. Talk to users about how they discovered it, what they used before, and what would make them leave. Analyze growth and drop-off rates against competitors. Ask why now: most ideas have been tried before, so understand why earlier attempts failed. Examine competition, moats, and whether the market is winner-take-all. Finally, trust your sixth sense: decisions sometimes need to happen faster, and intuition should not be underestimated.

Key points

  • The team is the constant in early-stage investing: would you work with this person?
  • Using the product and talking to users are among the most frequently skipped steps.
  • Ask why now: understand why previous attempts failed.
  • Sixth sense: sometimes decisions must be faster; do not underestimate intuition.

A Paradigm partner: How should you research early-stage projects? Founders At an early stage, the constant in the equation is usually the team. Ask founders about their strengths, weaknesses, and so on. Then ask yourself: would I work with this person? If so, that is a bullish signal. Size the opportunity Consider the market’s size today and theorize about how large it could become. Think ambitiously in making your projections. Use the product If a product exists, use it. Everyone knows this, but the step is often skipped. Experience it firsthand and understand its value proposition and offering. Founders also benefit from investors who understand and use their products. Talk to users Ask users: how did you hear about the product? What did you use before? How does it compare with alternatives? What do you think of the return on investment and value? What would make you leave? Data analysis Analyze key metrics such as growth and drop-off rates. Compare monthly or quarterly growth with competitors. Why now? Many ideas have been tried before; think of how many kinds of products we have already seen. Timing is critical. Work out why earlier attempts failed, and consider what is different now. Competition in the space Identify the biggest competitors and what makes this project different. Consider the moat they are building today and how it can expand. If they are not the market leader, write a report explaining why they will become one, or why this is not a winner-take-all market. Return calculations Sixth sense Sometimes you can skip steps 1->10, because a decision may need to be made faster than you expect. Be flexible with the analysis and prioritize. Above all, do not underestimate your intuition. Caseykcaruso, Paradigm partner
