I'm Managing Director of Prime Impact Fund, where we fund breakthrough start-ups that could have a big impact on climate. I also serve on the boards of five audacious tech start-up companies and two supporting organizations. In past lives I learned venture capital at Venrock, co-founded and led Lux Research, developed energy and environmental projects in China at MNL Partners, and forecasted technology futures at Forrester.
I really do live and breathe this stuff.
I'm also chromosomally incapable of keeping quiet. This blog hosts opinions (mine alone) on energy, venture capital, human behavior, start-ups, societal collapse, hope for the future, and everything in between: hopefully useful, usually numerate, and occasionally long-winded.
