Third Sphere Climate Summit

The Third Sphere Climate Summit will take place June 4-6, 2024, co-hosted by Atento Capital and Third Sphere, is an invitation-only gathering of the leading climate-focused founders and investors. The event is organized in Tulsa because of the historic ties to energy and the unique strengths in engineering and precision manufacturing required by a growing number of climate startups.

You’ll be joining ~120 people chosen from our broader Third Sphere and regional Tulsa communities. We’ve opted for a small gathering, to ensure that everyone you meet is a leader on a topic at the intersection of climate and startups. Just like you.

Summit venues will be all located in the heart of downtown Tulsa. A room block has been secured at the Hyatt Regency. Please book using the link provided in your registration confirmation email.

This is an invitation-only event. If you have received an invitation and RSVP'd, please complete your registration by May 10, 2024 to confirm your attendance. Registration includes access to all summit programming and meals.

Third Sphere supports climate hard-tech startups from seed and pre-seed investment to early stage lending. Atento Capital is an investment firm committed to building an inclusive, thriving ecosystem in Tulsa.
