Amir Weitman and Arié Benguigui have been childhood friends since meeting at a Geneva nursery school in 1978, a deep personal connection that predates and forms the foundation of their professional collaboration. Weitman served as the best man at Benguigui's 2016 wedding. In 2017, they co-founded Champel Capital, forming a partnership to invest in Israeli technology companies. As Managing Partner, Weitman shares in the firm's profits, management fees, and carried interest from its funds, including the $30 million second fund raised in 2022.
