Daniel Frankenstein

About Daniel Frankenstein

Brian is a bi-cultural operator-investor who was born and educated in the U.S. but spent most of his career embedded in Israel's innovation ecosystem, giving him hands-on experience helping Israeli founding teams with product-market fit and North American go-to-market strategies. Before co-founding Joule, he served as Director of Marketing at New York-based venture fund 21Ventures while living in Israel, where he designed and executed market entry strategies for 45+ portfolio companies—an unusual role where he functioned as a go-to-market strategist for an entire fund's portfolio rather than a single startup.
