Dear Friends of Greentown,

This summer, our startups have welcomed nearly 60 interns to their teams! We look forward to our member community growing each year as students complete hands-on prototyping in the labs, develop marketing campaigns, assist with business development, and more.

These students may go through a machine-shop training with the Greentown team, or attend community-wide intern bonding events, or get their first taste of what goes into being a CEO by sitting in on important meetings. Their roles may be funded by the fantastic internship programs run by the Massachusetts Clean Energy Center or TEX-E.

But there are two constants: first, they provide invaluable support to our startups’ small teams, and second, these students are taking the first steps to launching their own careers in climatetech—a growing industry building the jobs of tomorrow.

Hear from four of these students who are currently working with Greentown member Adept Materials!

Our community’s interns aren’t ready for the summer to end, and neither are we! We’re throwing one more celebration at each of our incubators this summer—a rooftop EnergyBar at Greentown Boston on Aug. 7 and a Transition On Tap at Greentown Houston on Aug. 21 featuring our new Head of Houston (more details below).

We hope to see you there!

Warmly,
The Greentown Team

Welcoming Lawson Gow as Our Head of Houston!

Earlier this month, we were thrilled to announce Lawson Gow as our new Head of Houston!

Lawson is no stranger to Houston’s innovation and entrepreneurial scene. As the founder of The Cannon and most recently a partner at Helium Capital, he’s spent his career building innovation hubs, backing bold startups, and championing founders. His energy, experience, and ecosystem instincts make him a powerful addition to Greentown—and a passionate advocate for our collective work.

Lawson will champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region. His extensive track record of supporting entrepreneurs, building community, and scaling ventures will play a critical role in Greentown Houston’s continued efforts to bolster the energy-innovation ecosystem.
