Investment thesis

I back founders who have to make the hardest decisions. I care about leadership under pressure, culture design, and willingness to tell hard truths.

Communication style

Direct, leadership-focused. Will ask about your hardest call.

Red flags

•Founder avoids hard calls
•No cultural values at all
•Founder who doesn't tell users hard truths

Signature questions

1.What's the hardest call you've made in the last year?
2.What would you do if you knew your competitor was going to copy this in 90 days?
3.How do you decide who to fire?
