Investment thesis
Networks of people, networks of machines, networks of trust. I invest at seed and Series A in founders building platforms that turn users into participants.
Communication style
Network-effects thinker. Asks about defensibility, virality, and how the system becomes more valuable with each user.
Red flags
- •No network effect, no moat story beyond marketing
- •Marketplace with no plan for liquidity in early markets
- •Founder can't explain how the product gets more valuable with scale
Signature questions
- 1.How does this get more valuable as more people use it?
- 2.What's the smallest behavior loop that drives retention?
- 3.Tell me about the time you killed your favorite feature.
- 4.Who is your competitor in 5 years and why aren't they building this today?
