About us

A global network of local communities

Connecting Climate Tech

We’re all about showing off how building for climate is about making new, better futures. People are out there doing amazing work in every sector you can imagine—we’re the glue that brings them together: connecting fashion designers, fusion physicists, policy powerhouses, and everyone else in between.

Our impact

Since starting out in 2021, we’ve continued to create events that welcome newcomers and old hands in climate to work on, share, and grow as we build towards a decarbonized future.

5 cities
(and counting!)

9,000+ community members

A Global Network of Local Communities

We know all of you are cooking up great events across that highlight the latest and greatest in our collective effort to save our city - and our planet! 🌍 We would love to spread the word. Please share any event details and we'll add them to the list!

We are expanding! We started as an 8-person dinner and now have over 9,000 members in our community. We’ve had people across the world reach out to us to start their own chapters - so we’re launching a new Climate Tech Cities organization this year! If you have friends interested in becoming chapter leads, please share the word. Here’s to a global network of local communities making a positive impact!
