Our Values

Start with the User

When our users succeed, we succeed. User success leads to healthier people everywhere.

People Matter

We believe that employee health is directly correlated to the success of H1, so we put as much rigor into improving our org as we do our business.

Know Why

We know why before taking action or investing time.

Beautiful Polished Rocks

The best ideas come with friction of diverging opinions and open, constructive feedback.

Be Quick, but Don't Rush

We move fast but we still sweat the correctness of our decisions, because our customers depend on us.

One Team

This is our company, and we operate together with a single vision: to build a healthier future.

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

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.
