Union Square Ventures

Union Square Ventures (USV) pursues a thesis‑driven strategy that targets startups operating at the “edge” of large, technology‑enabled markets undergoing rapid societal and technical change. The firm looks for products and go‑to‑market approaches that enable fast experimentation and that can bypass entrenched gatekeepers, favouring consumer‑first, developer‑first, open‑source and protocol‑based models. A central filter is network potential: USV asks whether a tool can evolve into a network of people, devices, data or assets that compounds in value as it grows. This network lens is tied to a broader “access” imperative—backing trusted brands that broaden access to knowledge, capital, well‑being, energy and other resources. Sector‑wise USV is a generalist, investing across social/media, marketplaces, developer tools, fintech, health, ed‑tech, web3/crypto, and climate/energy. Geography is global, with investments made worldwide across its Core, Climate and Opportunity funds. The firm explicitly avoids investing in direct competitors to preserve advocacy for founders. By keeping fund sizes modest, USV aligns general partners, limited partners and founders, allowing long‑term partnership and the flexibility to support both companies and protocols that fit this thesis.

USV’s investment decisions are made by the whole team in a collaborative group discussion rather than a formal vote. Partners, who are generalists, evaluate each opportunity through the lens of the firm’s thesis: rapid product iteration, technology‑enabled business models that incumbents can’t replicate, and clear pathways from a tool to a network that broadens access. Key signals include short product cycles, evidence of high usage or engagement (even when ARR is low), and a credible plan to scale the network effect. Deal‑breakers are direct competition with existing portfolio companies and any indication that a startup cannot remain independent in its market. USV typically leads or co‑leads Seed and Series‑A rounds with $2‑8 M checks and later‑stage Opportunity deals with $10‑20 M checks, providing board seats, talent introductions, and sustained follow‑on support. The firm’s emphasis on speed (feedback within 24 hours) and reliability (never backing out of a signed term sheet) reinforces its reputation as a committed partner, while the conflict‑avoidance policy safeguards advocacy for each founder.
