Fueling our people and communities.

eCos investments are now centered on the commercial real estate, service and sports sectors and supported by a centralized leadership team focused on finance, human and capital resources, marketing and business development.

Jonathan Ehrenfeld

Tradesman. Pioneer. Entrepreneur.

In elementary school, Jonathan was selling soda to his peers. At 19, he became a self-taught electrician, then carpenter. One could say he’s often chosen the road less traveled, taking risks and diving into opportunities that few others would have pursued, industries few were willing to touch. He’s always on the lookout for “great bones” and asking himself the same question:
What will it take to build value here?
With a focus on growing impact and achieving success in less chartered industries, he’s been willing to face rejection, and loss. He’s put his neck on the line for his investments, his principles and his people. Assessing risk, taking faith in the reward, he leads his companies with a confidence and willingness to trust his teams and try new things.

With a mentor approach to problem solving and business development, respect for team governance and autonomous management, Jonathan’s leadership is the undercurrent to success for the eCos system.
