About Personalis, Inc.

Personalis, Inc., founded in 2011, is making significant strides in the Biotechnology and Health Care industries with its focus on ultrasensitive ctDNA testing.

The most recent funding round, a substantial $150.10M post-IPO equity investment dated January 27, 2021, underscores investor confidence in its technological potential and market impact.
