Forerunner Ventures
Forerunner Ventures is an early-stage venture capital firm founded in 2012 by Kirsten Green and headquartered in San Francisco, California. Forerunner backs founders building category-defining companies, investing with early conviction at the seed and Series A stages (with selective pre-seed), typically writing initial checks in the $1M-$15M range. The firm invests across consumer, commerce, health and wellness, consumer finance, marketplaces and services, personal systems, and platforms and infrastructure, increasingly viewed through AI lenses (AI as agent, AI as infrastructure, AI as intelligence layer). Forerunner has raised nearly $3B in assets under management across seven flagship funds, with its most recent Fund VII a $500M early-stage vehicle. Its portfolio includes category leaders such as Chime, Warby Parker, Glossier, Hims & Hers, Oura, Faire, The Farmer's Dog, Dollar Shave Club, Curology, Away, Ritual, and Chime, along with a growing cohort of AI-native companies including Decagon, Suno, Slingshot AI, and Monarch Money.

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.
