3X4 Genetics CEOs Jason Haddock and Yael Joffe Put Seattle Move on Hold After COVID-19 and Trump Employment Visa Ban

3X4 Genetics, a South African at-home genetic testing startup led by CEO Jason Haddock and co‑founder Yael Joffe, planned to relocate to Seattle after securing investment and U.S. go‑to‑market plans, but COVID‑19 and a Trump administration visa ban on employment-based nonimmigrant visas left their move and business rollout in limbo. The company focuses on nutrigenomics tests prescribed through healthcare practitioners to guide nutrition-based interventions and physician-patient conversations.
