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.

- Using the product and talking to users are among the most frequently skipped steps.
