PurposeEnergy Leadership

PurposeEnergy is led by an experienced, highly respected leadership that includes a seasoned board of directors and capital investors with a proven track record for funding and advising successful start-up technology companies.

Many of our board members and advisors are from, or are affiliated with, the Massachusetts Institute of Technology as is PurposeEnergy founder, Eric Fitch.

Eric Fitch, Founder & CEO

Founder & CEO Eric Fitch is our visionary leader who first imagined and then built a better solution for treating the organic waste produced by beverage and food manufacturing processes. His passion for technology (fine-tuned during his education at MIT), his love for the environment, and his years spent helping to launch a number of successful start-ups (biotech, clean tech, photonics, consumer electronics) inspired Fitch to establish PurposeEnergy and start “Saving the Earth. One beer at a time™” (Purpose Energy’s original tagline).

As the company’s leader, Eric is focused on strategic development, operations, and sales and is personally involved in every engagement and installation. When he is not traveling the country, visiting customers, touring production plants, conducting a Blitz Engineering Study or wastewater audit, and overseeing the installation of bioreactors, he can be found at home in Arlington, Massachusetts with his brilliant and beautiful wife and young family.

Todd Hasselbeck, Vice President, Worldwide Sales

If you happened to be in Mozambique’s Gorongosa National Park from 2010 to 2012, you might have encountered Todd Hasselbeck leading the park’s restoration. He has also worked as a Clean Energy Fellow at the New England Clean Energy Council and as an advisor to the renewable energy industry. Add corporate positions including Operations Director at Cisco Systems and VP of International Sales at Boston Technology and you realize that Todd brings a unique resume to the table.

A graduate of Cornell University, Todd is at the helm of PurposeEnergy’s worldwide sales organization (did we mention he has built several worldwide sales organizations in the Americas, Africa, Asia and Europe?) His is focused on identifying prospective customers, building PurposeEnergy’s awareness across the food and beverage industry, managing the PurposeEnergy sales team and, of course, making sales presentations across the land.
