Business Activities


“Opportunities don’t happen. You create them.”

I’ve founded and scaled companies. I’ve founded and failed companies. I’ve worked with some of the great cleantech success stories, their founders, VC’s and leadership teams. I’ve learned a lot. I have grey hair and wrinkles! My passion is to use these experiences, these lessons, to accelerate the clean energy and mobility transitions, working with entrepreneurs, founders, Investors and industry Thought Leaders to create opportunities, jobs and a better environment and society.

I also have a passion for talent, and believe the key to the success of any business is having the right people in the right place, at the right time. For this reason I’ve focused on building and buying executive search and recruitment businesses that serve the cleantech sector globally.

I’m open to hear about opportunities for

  • Business owners looking to sell their business
  • JV and Partnerships
  • NED/Board Advisor roles
  • Mentoring
  • Scale up support
  • Speaking
