Venture Capital

Initialized Capital

Initialized Capital is a seed-stage venture capital firm founded in 2012 by Garry Tan, Alexis Ohanian, and Harjeet (Harj) Taggar, with offices in San Francisco and New York. The firm is hyper-focused on the seed stage, typically investing before a startup's success strikes other investors as inevitable and favoring companies that have raised little to no prior capital. Rather than thematic investing, Initialized centers its thesis on strong founding teams and acts as a de facto extended founding team from 0 to 1, providing operational support across product design, engineering, recruiting, storytelling, go-to-market, and Series A fundraising. It invests broadly across enterprise SaaS, consumer, marketplaces, fintech, crypto, healthcare, climate, hardware, real estate, and frontier/AI technology. As of 2021 the firm had raised more than $3.2B across its funds and has backed 200+ companies, including 28 unicorns such as Coinbase, Instacart, Cruise, Flexport, Reddit, Opendoor, Rippling, and Patreon, with portfolio companies creating an aggregate of over $200B in market value.

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.
