Venture Capital

Menlo Ventures

Menlo Ventures is an early-stage venture capital firm founded in 1976 and headquartered in Menlo Park and San Francisco, California, that invests in transformative technology companies across the full early lifecycle. Its strategy spans "the Three Stages of Early" — Inception (validating early ideas, including via the Inception Fund and the Anthology Fund AI accelerator built with Anthropic), Venture (Series A/B), and Inflection (early growth). Menlo invests across artificial intelligence, bio and healthcare, consumer, cybersecurity, defense, fintech, infrastructure, robotics and hardware, SaaS, and supply chain and automation, primarily in North America. Over roughly five decades the firm reports backing companies that produced 85+ public companies and 170+ mergers and acquisitions, with a portfolio that includes Anthropic, Uber, Roku, Chime, Carta, Benchling, Pinecone, Netlify, and Warby Parker. In 2026 Menlo announced $3 billion in fresh capital, the largest raise in the firm's history, and reports $7.6B+ in assets under management. Its ethos is "when we invest, we're invested" — active, hands-on support beyond capital.

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.
