About Brian Rosenzweig

Brian Rosenzweig, a co-founder and partner at Joule Ventures, invests at the pre-seed and seed stages in Israeli-founded enterprise technology businesses commercializing in the U.S., with typical check sizes of $1M–$3M. His portfolio focuses on B2B software sectors including cybersecurity, data, AI/ML, and fintech, targeting solutions that address inefficiencies in modern enterprises. Notable portfolio companies include BioCatch (acquired for $1.3B), Coralogix, Arnica, Pynt, and AccSenSe. Rosenzweig’s distinctive thesis emphasizes a “business building” approach over chasing trendy tech, leveraging Joule’s bi-national infrastructure to support founders from Israel through U.S. market entry.
