Company Profile

Phosphor Capital is a venture capital firm founded in early 2024 by YC alumnus Kulveer Taggar and based in San Francisco. The firm invests exclusively in Y Combinator companies at early stages, leveraging Taggar’s deep network and founder experience within the YC ecosystem.

Operating under a solo General Partner structure, Phosphor delivers founder-first support—offering hands-on guidance, help with key hires, and empathy born from Taggar’s own startup journey. It stands out for its personal, high-touch investment approach, often engaging in critical conversations even outside typical business hours.

Since inception, Phosphor has raised $34 million across two funds, with backing from top-tier asset managers, family offices, and YC CEO Garry Tan. The firm has made over 200 investments into YC startups—typically writing checks between $100,000 and $500,000—and has already backed companies like Delve, Reducto, Gumloop, and Circleback, many of which have advanced to Series A rounds.
