Arivale, the genetic testing and personal health coaching startup co-founded by genomics pioneer Leroy “Lee” Hood, shut down unexpectedly Wednesday — bringing an abrupt end to its ambitions to transform the lives of Americans through a new field that Hood dubbed “scientific wellness.” All of the Seattle-based company’s approximately 120 employees were let go as of noon today, Arivale CEO Clayton Lewis confirmed in an interview. Arivale raised more than $50 million over its lifetime. The company offered ongoing wellness and nutritional coaching tailored to the results of each person’s genetic, blood and microbiome tests.
