The EIF investment team comprises James Everett, Devin Whatley, Geoffrey Eisenberg, and Sasha Brown. The team members have complementary skills and backgrounds and take responsibility for leading different areas of the fund’s work. James uses his extensive sector knowledge and investment analysis experience to lead EIF’s research, due diligence, and strategy development. Devin draws upon significant financial training along with more than 20 years experience managing operations and start-up ventures to lead finance and operations-focused due diligence; he also manages the EIF’s day-to-day operations. Principal Geoffrey Eisenberg works with James on investment due diligence and strategy development.  Sasha supports due diligence, strategy development, firm operations, and financial structuring.

One of the EIF’s key points of differentiation is each team member’s demonstrated passion for sustainability. The team has not happened upon cleantech as the next hot investment thesis, as have many investors competing in the space. Rather, each member of the group has been personally committed for many years to the mission of identifying and promoting environmentally sustainable, profitable businesses.
