We support founders who turn theory into action as they work to build a better world for everyone. We fundamentally reshape broken global systems by connecting the best people reimagining our world to resources and each other, using early stage capital to upgrade systems.
We never publish partner emails directly — score your deck to unlock contacts for the firms ranked as best-fit.
Third Sphere writes first institutional checks where the founder + early product matter more than traction. The seed market is the most dispersed segment of venture; matching to thesis (sector, stage, geography) is where most cold outreach succeeds or fails. Claude Fundraiser tracks Third Sphere alongside 45,000+ other active investors, ranked weekly by recent-deal momentum, sector concentration, and partner activity.
Drop your pitch. Claude scores it on the 8 dimensions VCs read for and ranks the 45,000+ active investors in the database by fit. Third Sphere is one of them — and we'll tell you exactly where they sit in your top 100.
