For over a decade, I’ve worked in almost every part of climate tech and sustainability.

  • Executive at a high-growth startup with a successful exit

  • Early-stage investing

  • Growth-stage investing

Why “Sustainable Returns”? I’m not interested in anything that’s not sustainable. Relationships, investing frameworks, careers, reading habits, exercise habits, etc… If I can’t keep it going for decades, I’m not interested in it.

Subscribe here as I share in plain English what I’ve learned, break down the investment trends impacting the energy transition, and explore enduring investing and life concepts.
