Why it's hard
- Strict no-direct-competitor policy narrows eligibility
- Thesis fit around networks, access, and market structure is non-negotiable
- Typically seeks companies with potential to become independent platforms, not point solutions
- Strong brand means USV can choose selectively among high-quality inbound opportunities
USV is highly selective because it applies a distinctive thesis rather than broad category investing, leads many early rounds, and avoids any direct portfolio conflicts. Founders must fit both the network/access worldview and the bar for building an independent, category-defining company or protocol.
Green flags
What drives a yes for this firm.
- Clear path from product utility to durable network effects
- Evidence of strong usage, engagement, or community pull even before significant revenue
- A go-to-market model incumbents cannot easily copy because of speed, architecture, or community
- Alignment with USV's access thesis and long-term market independence
- Founders who can move quickly, iterate fast, and build trusted brands
Red flags
What kills deals and gets a fast no.
- Direct competition with an existing USV portfolio company
- No credible path from product to defensible network effects
- A business likely to be acquired quickly rather than become an independent platform
- Weak usage or retention hidden behind storytelling about massive TAM
- Founders who cannot articulate how the market shift structurally favors their model
How to win
Patterns that lead to successful pitches.
- Show how the product evolves from a wedge into a self-reinforcing network
- Lead with engagement, retention, community activity, or ecosystem growth if revenue is still early
- Explain why incumbents or gatekeepers cannot easily replicate the go-to-market motion
- Tie the company to a broader access-expanding mission in a large changing market
- Demonstrate speed: fast shipping cadence, rapid learning loops, and a clear roadmap to scale

Investment thesis
Core beliefs and strategy behind their investing approach.
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.
Decision patterns
How they evaluate and make investment decisions.
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.
Risk appetite
USV adopts an aggressive, conviction‑led risk profile, comfortable backing pre‑revenue or early‑stage startups whose value is driven more by engagement and network effects than by immediate ARR. The firm usually leads or co‑leads deals, taking an active board role and committing to follow‑on rounds. Speed and reliability are core: founders receive feedback within 24 hours of a full‑team pitch and USV has never walked away from a signed term sheet. Discipline comes from small fund sizes and a strict policy against investing in direct competitors, which helps maintain long‑term alignment while tolerating higher market and regulatory risk in areas like crypto and climate.
