It takes a decade to build a great company.
Our mission is to make sure founders are shining brightly for the full journey.
We invest early, bring conviction and help relentlessly. Typical check size is $100k - $500k.
Zeus Living (YC S11) was my moonshot. Zero to $450M revenue, $200M raised, pandemic pivots, layoffs and ultimately, a 2023 sale to Blueground. Good, but not the independent company outcome I wanted. I've lived every founder extreme: pivot hell, blitzscaling, cofounder turnover, board pressure. I now channel those scars into an unfair edge for the next wave of YC founders.
I've been a part of the YC ecosystem for 18 years. I've cofounded companies with Patrick and John Collison, Harj Taggar and Tom Blomfield, and written 200+ post YC checks. Phosphor Capital exists to turn that lived insight into being the best investor in YC companies. Phosphor Capital launched in January 2024 with a $17M Fund I.
