Mission Statement

Episona is an epigenetics data company focused on improving outcomes in reproductive health. We believe epigenetics presents a massive opportunity to understand how the environment can shape heritable human health and disease.

We believe in creating products backed by strong science, with clear utility, and a sharp focus on user experience. Our first product, Seed, goes well beyond an easy to understand test result – we provide education, support, and counseling so that we can make a positive impact in our users’ lives.

Our mission is to empower you to make informed decisions about your reproductive health, while building a community that grows our understanding of how behaviors, environmental exposures, and aging can alter how our DNA works.
