It was an honor to host MA Lieutenant Governor Kim Driscoll () for a visit to Greentown this week! Lt. Governor Driscoll joined us for a tour through our prototyping lab and a roundtable discussion with 19 of our founders to discuss the Commonwealth’s support for climatetech innovators and how growing startups can best take advantage of this ecosystem to start, grow, and scale here. 

We are grateful to the Office of the Massachusetts Governor Maura Healey () and LG Driscoll, and Somerville Mayor , State Rep. , and CEO Ben Downing for joining and providing the opportunity for our entrepreneurs to have a direct dialogue with local and regional administrations, share how they’ve benefited from local and regional support, and exchange ideas for how to continue investing in key growth industries, from energy storage to maritime innovation to building sustainability. 

We are deeply proud to be and to serve as home to startups that not only begin here, but also grow and mature right here in the Commonwealth. Thank you to the Healey-Driscoll Administration for your continued support for our community!

Sending a huge thank you to our partner for welcoming a group of Greentown Houston members to the SLB Rosharon Campus (SRC) to learn more about SLB’s capabilities and pathways for collaboration with startups! Our members met with leadership and technical staff from SRC and the Enabling Technology Development teams, exchanging insights on how novel technologies can move from incubation to industrial deployment, before touring the site. We toured the state‑of‑the‑art test facility at SRC and were energized by the technologies showcased.

We are looking forward to seeing the collaborations that may emerge from this visit and are grateful to partners like SLB for their strong commitment to scaling climate tech solutions. Thanks especially to Laurent Alteirac, Paulo Valdivia, Akhil Bahl, and Huilin Tu for welcoming us!
