Tobias Leaves Imperium

Martin Tobias has stepped down as chairman and CEO of Imperium Renewables, a Seattle-based biodiesel producer that is in registration for a $345 million IPO. No reason was given. Tobias founded the company in 2005, after leaving his job as a venture partner with Ignition Partners.


It has since raised funding from firms like Nth Power, Technology Partners, Blackrock Private Equity, Attractor Investment Management, Robeco Private Equity, Silver Point Capital and Capricorn Management.


Imperium said that current president John Plaza would take over as interim CEO, while Nth Power's Nancy Floyd will become chairwoman. Tobias will remain on the board of directors.
