Flagship Labs 127 is an early-stage company in the Flagship Pioneering ecosystem, developing a first-in-category platform anchored in novel device technology that could change how human wellness is understood and managed. We’re building the science through a rigorous, hypothesis-driven program, and testing the market with the same rigor by running live campaigns against pass/fail criteria we set in advance. The team is small and the product is headed into a brand-new market.

Flagship Labs 127 was founded by Flagship Pioneering’s venture creation engine that invents and builds platform companies, each with the potential for multiple products that transform human health or sustainability. Since its launch in 2000, Flagship has originated and fostered more than 100 scientific ventures, resulting in more than $90 billion in aggregate value. Many of the company’s Flagship has founded have addressed humanity’s most urgent challenges: vaccinating billions of people against COVID-19, curing intractable diseases, improving human health, preempting illness, and feeding the world by improving the resiliency and sustainability of agriculture.

Flagship has been recognized twice on FORTUNE’s "Change the World" list, an annual ranking of companies that have made a positive social and environmental impact through activities that are part of their core business strategies and has been twice named to Fast Company’s annual list of the World’s Most Innovative Companies.
