## About Vertex Ventures US

Vertex Ventures US is a boutique venture capital firm investing in exciting companies across software infrastructure, dev tools, and more. The team describes itself as VCs who get it — as founders and operators themselves, they partner with and invest in early-stage founders building infrastructure and SaaS companies.

Founded in 2015 by In Sik Rhee — a former founder of Kiva Software (acquired by Netscape) and Loudcloud/Opsware (IPO'd, acquired by HP) — the firm is based in Los Altos, California, alongside General Partners Jonathan Heiliger and Sandeep Bhadra.

Vertex US is part of the global Vertex Ventures network, with affiliates in Israel, China, Southeast Asia, India, and Japan. The firm typically leads or co-leads Seed and Series A rounds, writing checks between $500,000 and $10 million.

Portfolio companies include LaunchDarkly, Evisort (acquired by Workday), Hasura, Docker, Vectara, Tulip, HUMAN Security, and Cyberhaven. Its approach emphasizes operator empathy — helping technical founders nail go-to-market strategy and build exceptional teams, drawing on lessons from its partners' own company-building journeys.
