H1 Leadership

Ariel Katz

Co-Founder & CEO

Ariel Katz started his first company in college, ResearchConnection, to help connect students with research opportunities. That company grew to over 40 universities and was eventually acquired by the Jefferson Accelerator Fund, Bill and Melinda Gates Foundation and the Ewing Kauffman Foundation.

In 2017, Ariel started to think about problems to solve in healthcare. Around that time he got connected with Ian, with whom he co-founded H1.

Ian Sax

Co-Founder & President

Ian Sax has been building businesses for over two decades.  He began his “start up” career at The Carson Group, where he built the firm's global people, institution, and shareholder platform prior to its acquisition by Thomson Reuters in 2000.

He also successfully established Capital IQ’s first data collection group in India before he co-founded Shore Group in 2006, where he served as CEO until the successful spin-out of H1 in 2019.
