The current President and CEO at Serious Energy is Tassilo Baeuerle, who led "General Biofuels from unknown startup to respected developer of biomass pellet facilities with projects throughout North America," according to his company bio. He's a manufacturing guy in charge of a firm looking to return to its manufacturing roots, according to a source close to the firm.

In April we reported that Kevin Surace, the man who since 2008 led Serious Materials through a changing set of business strategies -- green building materials, energy efficiency software, project financing -- was no longer CEO. He lost the job in February, and was listed as chairman and co-founder, while Marc Porat, co-founder of Serious and a handful of other Silicon Valley green startups, had taken the helm. Surace is now listed on LinkedIn as the CEO of PushToTest, which according to the company website is "an open-source web and application load and performance testing tool that tests processes that use Rich Internet Applications." Frank Cohen is still listed as CEO and Founder of PushToTest on the company website.

Jeff St. John did an investigation into the shifting personnel and business plans at Serious earlier this year.
