Trinity Ventures

Trinity Ventures is an early-stage venture capital firm founded in 1986 and headquartered in Menlo Park, California, with more than three decades of history backing mission-driven entrepreneurs across technology and consumer markets. The firm takes a deliberately personal, low-capital-to-partner approach to early-stage investing, positioning itself as "the call you want to make, not the call you have to make" and emphasizing intellectual candor and lasting founder relationships. Trinity invests primarily at seed, Series A and Series B, with checks generally ranging from roughly $1 million to $15 million and averaging around $5 million. Its focus spans enterprise software and cloud infrastructure, developer tools, fintech, digital media and marketing technology, consumer products and services, healthcare, and artificial intelligence. Over nine funds the firm has managed on the order of $1.3 billion in assets and produced a track record that includes multiple unicorns, IPOs and roughly 130 acquisitions. Notable investments include Starbucks, New Relic, Auth0, Turo, Care.com, Zulily, Blue Nile, Aruba Networks, Infoblox, Cohesity, Outreach, InfluxData, Contentful and Docker. Trinity invests primarily in the United States.

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.
