Venture Capital

Thrive Capital

Thrive Capital is a venture capital firm founded in 2009 by Joshua Kushner and headquartered in the Puck Building in New York City. The firm builds and invests in internet, software, and technology-enabled companies across the full lifecycle, from early-stage seed bets through growth and late-stage positions, and also incubates new companies through its Thrive Incubations program. Thrive concentrates its capital in a relatively small number of high-conviction positions across artificial intelligence, fintech, enterprise software, consumer internet, media and entertainment, healthcare, defense technology, and developer tools. The firm has scaled its funds steadily from a $5M first fund in 2009 to Thrive X, its tenth fund, which closed in early 2026 at over $10 billion (roughly $1B for early-stage and $9B for growth), bringing the firm to approximately $50 billion in assets under management. Nitin Nohria, the former dean of Harvard Business School, serves as executive chairman. Thrive is widely known as one of the earliest and most significant backers of OpenAI, Stripe, and SpaceX, and its portfolio includes Instagram, GitHub, Databricks, Ramp, Scale AI, Anduril, Robinhood, and Plaid.

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
