Scientist, Protein Expression and Purification
About Apriori Bio
Apriori is working to create a world that is protected against viral threats. Our pioneering approach centers on a unique technology platform, Octavia™, which allows us to survey the entire landscape of existing and potential variants to design new vaccines against the most threatening viruses. Octavia can also inform public health policy in real time by predicting the impact of emerging variants. Apriori was founded in 2020 in Flagship Labs, a unit of Flagship Pioneering.
Apriori Bio is an early-stage biotechnology company with an ambitious and exciting mission: to provide humanity with variant-resilient protection against rapidly-evolving viruses. The company is developing a revolutionary approach to this challenge and recruiting a team of top-tier scientists to develop its Octavia™ platform.
Flagship Pioneering is a biotechnology company 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 companies 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.
