Over the past 16 years, I have been involved in 5 successful startup companies ranging from an energy company, to several .com companies. Now I am focusing all of my attention on creating the tipping point in the sustainability movement by pushing initiatives in government, business and the broader social landscape. 
Many people are curious, what I am doing since I left Powerset. Well, the short story is that I have decided to dedicate myself to what I call the new Green Economy and I am working on several initiatives with other leaders in government and businesses that all fall under the responsibility of non-profit that I am founding called SF Green. A Carbon Fund for San Francisco?
In a forward released a couple of weeks ago, the Mayor's office announced it would be creating a San Francisco Carbon Fund for local green activities designed to mitigate or “offset” greenhouse gas emissions. I'm going to be getting directly involved in this one and I will let you know how its going.There isn't much detail yet, but I have a meeting that I am scheduling with a rep from the Mayor's office to discuss. I have a lot of innovative ideas in this sector (my first gig was as an energy capacity trader at an energy trading company)
I don't want to spill the beans on my ideas just yet, but I will let everyone know how its going and post when there is something solid to report. If you have ideas for how a city carbon fund could work, let me know.
