Speaker

Paul Buchheit, Y Combinator partner and Gmail inventor, shares lessons from his startup investing at Startup Investor School Day 2 with the Y Combinator audience.

Why promising startups can look like bad ideas

Buchheit says startups often need ideas that established companies would dismiss as too small, strange, or risky. He points to Google, which Larry Page and Sergey Brin tried to sell for $1 million before its potential was clear. He also describes joining Google because he used its search product and was excited about its Linux infrastructure, not because he expected a big return.

Bet on founders who make progress

Buchheit says he looks for founders who are better than he is and can explain their ideas clearly. Meraki built and sold mesh Wi-Fi hardware without raising money, while Kyle Vogt built a streaming server over a weekend that helped Justin.tv survive. He also highlights Blake Scholl’s clear explanation of how his supersonic jet company would address problems that doomed the Concorde.

Mistakes that lead to missed investments

Buchheit missed an opportunity to invest in Dropbox after canceling a meeting with Drew Houston, and moved too slowly on Airbnb before it signed a term sheet with Sequoia. He says investors should make deliberate decisions, since promising companies may not wait. He also warns that a low valuation, sympathy for founders, cynical ideas, or impressive numbers alone have not led to good returns for him.

A practical founder checklist

Buchheit looks for clear communication, fast execution, resourcefulness, ambitious or playful ideas, the ability to attract talent, a product people want, and determination. He suggests asking what founders accomplished in the past month and looking for a rising trajectory, even when current numbers are small. He also advises probing for commitment and learning how founders respond to setbacks.

Accept uncertainty and avoid overlearning

Buchheit says seed investing involves substantial luck, so investors should not build elaborate theories from every win or loss. He relies on founders’ expertise when evaluating unfamiliar fields, including deep technology and biotech, where demand may be clear but technical success is uncertain. He warns that abundant funding can shield founders from customers and reality, and says investors need to balance learning from past mistakes with staying open to new opportunities.

Takeaways

  • Look for founders who explain complex ideas clearly and can show what they have accomplished recently.
  • Favor teams that test ideas quickly and make meaningful progress with limited resources.
  • Move decisively when a company looks promising; delay can mean losing access to it.
  • Assess whether a product creates real value, rather than relying on price, traction, or a compelling story alone.
  • Treat outcomes as partly shaped by luck, and avoid turning one failure into a rule against an entire category.
