WHAT THEY DO

A first-check firm backing climate, resilience, and urban technology built for deployment. Born from an urban-tech thesis, Third Sphere invests where hardware, infrastructure, and software meet the physical systems cities and communities depend on. The partners are known for practical underwriting of hard-to-finance categories that most generalist capital avoids. Its ambition is to get climate and resilience technology out of the lab and into the built world faster than the incumbents believe possible.

WHY WE INVESTED

We invested because they underwrite what most early-stage capital abandoned: hard-to-finance climate and resilience hardware, in the exact window where funding retreated while the science accelerated. Their deployment-first selection matches our physical-economy weighting, and it keeps us early in categories generalists still avoid.

The 1200 hour is noon, the sun at its highest point, and it is midnight, the moment a new day begins. It is forwardness, encoded as a name.
More than a clock, the mark is a compass pointing to true north, and a network: every node, person, idea, skill, company, fund, unique, but most useful when connected.
