Venture Capital

Craft Ventures

Craft Ventures is a San Francisco-based venture capital firm founded in late 2017 by repeat entrepreneurs David Sacks and Bill Lee, built "by founders for founders" and rooted in the operator playbook of the PayPal Mafia. The firm invests across early and growth stages, writing checks that range from micro-seed positions through double-digit millions, and specializes in B2B SaaS, marketplaces, and enterprise software prized for high-growth, high-margin, recurring-revenue economics. Craft is known for its rigorous, metrics-driven SaaS operating framework and hands-on support spanning talent, go-to-market, community, and finance. Beyond core SaaS, the portfolio spans artificial intelligence, developer tools, fintech and crypto, cybersecurity, digital health, defense, and frontier technology. The firm manages roughly $3.3 billion in assets across four early-stage funds and two growth funds, including Craft Ventures IV ($712M) and Craft Ventures Growth II ($608M). Notable investments include Airbnb, Affirm, Reddit, Uber, Lyft, Palantir, Slack, ElevenLabs, Supabase, Anduril, and Neuralink. Headquartered in San Francisco, with offices in New York City and Austin, Texas, and a primarily United States geographic focus.

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.
