Description

Union Square Ventures (USV) is a prominent New York City-based venture capital firm established in 2003, renowned for its early and growth-stage investments in internet-related companies. The firm distinguishes itself by focusing on businesses that leverage network effects, open protocols, and large-scale user participation, often seeking to invest in companies building "large networks of engaged users." USV's investment philosophy centers on the transformative power of technology to create new markets and disrupt existing ones, particularly within the realms of web services, digital media, and consumer applications.

USV primarily targets early-stage companies, typically participating in Seed, Series A, and Series B rounds.

These investments underscore their ability to identify and back disruptive technologies with significant market potential. The firm has consistently raised substantial capital, with their most recent funds, Early Stage V and Opportunities Fund V, both closing at $200 million each in 2021. This substantial capital base allows USV to make meaningful initial investments and provide robust follow-on support, typically deploying first checks ranging from $3 million to $15 million, reflecting their commitment to impactful early-stage funding.
