Venture Capital

First Round Capital

First Round Capital is a seed-stage venture capital firm founded in 2004 by Josh Kopelman and Howard Morgan, headquartered in San Francisco with offices in New York and Philadelphia. First Round invests almost exclusively at the earliest stages of company creation, typically writing lead checks in the $750K to $4M range, and partners (many of them former founders) work side-by-side with companies through their first few years. The firm is a generalist that seeks contrarian insight into how markets work, with concentration in enterprise software, AI, fintech, healthcare, hardware, and consumer. Since founding it has backed 500+ startups and was the first institutional investor in Uber; its portfolio includes Notion, Roblox, Square, Looker, Upstart, Verkada, Warby Parker, Flatiron Health, and Clay. First Round also runs The Review, a widely read operator-focused editorial publication, and self-reports roughly $2.5B in assets under management.

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.
