Years
01 / Investment Thesis
I invest in
what’s next
My approach is conviction-driven. I hold positions for 7–12 years and work closely with founders through every stage. I don't spray and pray — I concentrate and commit.
Rich Text
01
Technology that changes behavior
The best investments don't just improve existing workflows — they make old behaviors obsolete.
02
Exceptional founding teams
Ideas are cheap. The team that executes through ambiguity is what I'm really backing.
03
Large, underserved markets
I'm drawn to categories where incumbents have grown complacent and customers have accepted mediocrity.
04
Long-term thinking
Decade-scale thinking is a genuine competitive edge. Most founders — and investors — can't sustain it.
05
Sustainable competitive advantage
Moats matter. Network effects, proprietary data, and deep switching costs separate durable companies from features.
