Driven by its mission to advance global access to low-carbon, dispatchable energy, Mainspring has developed a new category of power generation — the linear generator — that delivers onsite, fuel-flexible power at lower cost and lower carbon than the electric grid. We envision a path to the resilient, affordable, net zero-carbon grid of the future… Read Our Vision >

EXECUTIVE TEAM

Slide Shannon Miller Chief Executive
Officer & Founder
Shannon Miller co-founded EtaGen in 2010 and leads the company as CEO. While completing her doctorate at Stanford, where she was a National Science Foundation Fellow, Shannon received funding from the Global Climate Energy Project to advance her research on methods for improving efficiency of fuel conversion to electricity. In conducting this research, Shannon collaborated with Matt Svrcek to design and develop the early prototype that served as the foundation for EtaGen's high-efficiency, linear generator technology. She holds a B.S., M.S. and Ph.D. in mechanical engineering from Stanford University and was recognized in 2012 by the MIT Technology Review as one of “35 Innovators Under 35." Adam Simpson Chief Product
Officer & Founder
Matt Svrcek Chief Technology
Officer & Founder
Matt Svrcek co-founded EtaGen and leads research and development as Chief Technology Officer. While completing his doctorate as a Stanford Graduate Fellow, he received funding from the Global Climate and Energy Project to investigate the efficiency and emissions impact of reacting various fuels under high compression. In performing this research, Matt collaborated with Shannon Miller to design and develop the early prototype that served as the foundation for EtaGen's high-efficiency, linear generator technology. Prior to EtaGen, Matt served as research manager at Renewable Energy Policy Project in Washington DC, where he analyzed the economic benefits of renewable energy manufacturing. He holds a B.S., M.S. and Ph.D. in mechanical engineering from Stanford University. Adam Simpson co-founded EtaGen and leads product, external affairs, and intellectual property as Chief Product Officer. While completing his doctorate at Stanford, Adam received funding from the Global Climate Energy Project to advance multi-criteria analysis techniques for making decisions in energy with the goal of guiding economically and environmentally sound investments and policies in a complex and evolving sector. Prior to EtaGen and during his graduate work, Adam consulted for Sandia National Laboratory and various energy-focused venture firms in Silicon Valley. He holds a B.S. in mechanical engineering from Lafayette College and an M.S. and Ph.D. in mechanical engineering from Stanford University. David DeGraaff SVP Engineering
& Operations
Dave DeGraaff, Senior Vice President of Engineering and Operations, joined EtaGen in early 2017 to help bring linear generation technology to customers. Prior to joining EtaGen, Dave served as vice president of solar panels at SunPower Corp., where he led module engineering, product management, and reliability. He also served as vice president of engineering at startup Ausra, Inc., where he helped to successfully commercialize a state-of-the-art solar-thermal boiler technology for utility-scale power production that was acquired by Areva. Previous to that, Dave held leadership positions in software companies and was a faculty member in the Thermoscience division of Stanford. Dave holds a B.S.E. in mechanical engineering from Princeton University and a Ph.D. in mechanical engineering from Stanford University. Ken Poczekaj VP Global Supply
Chain & Operations
Ken Poczekaj, Vice President of Global Supply Chain and Operations, brings more than a decade of senior management experience in global procurement and supply chain operations to EtaGen. As president of global enterprise execution for Emerson Electric, Ken directed $2.1 billion in global procurement and logistics operations and managed a network of manufacturing sites and warehouses worldwide. When Emerson spun out its power network business in 2016, renaming it Vertiv, Ken became Vertiv’s chief procurement officer. Ken has also served in a number of other leadership positions in the U.S. and Europe and helped to establish new best practices for supply chain management in the data center industry. Ken holds a B.S. in industrial engineering from Southern Illinois University and an M.S. in manufacturing and operations from Washington University. Yannick Roux VP New Product
Introduction
Yannick Roux, Vice President of New Product Introduction, joined EtaGen in 2018 following 11 years at Tesla, where he most recently served as director of manufacturing engineering. While at Tesla, Yannick directed the design and deployment of drive-unit manufacturing lines for the Tesla Roadster, Model S, Model X and Model 3, as well as the Battery Pack manufacturing line at the Tesla Gigafactory in Nevada. He developed his expertise in automation equipment, manufacturing and factory deployment in Europe at the Automation division of Renault-Nissan and Fiat, and has served in additional technical management roles in Europe and the Middle East. A native of France, Yannick relocated to the U.S. in 2006 and became an American citizen in 2015. He holds a M.S. in mechanical engineering from ENSIAME in France.
