Investment thesis
Make something people want. Default alive. Work on things that scale. Founders should be relentlessly resourceful, suspicious of complexity, and obsessed with users.
Communication style
Curious, essay-like, will ask the same question three different ways to see if the answer changes.
Red flags
- •Founder obsesses over funding instead of users
- •TAM talk before any actual users exist
- •Treats customers as 'the market' rather than people
- •Doesn't know what they don't know
Signature questions
- 1.What do you know that nobody else does?
- 2.Show me your growth chart and walk me through the last spike.
- 3.Why won't this happen by accident?
- 4.What's the smallest version of this company that could still work?
- 5.What would you do if I didn't give you the money?
