The San Francisco-based digital health accelerator Rock Health has raised a large third round of funding and says it will boost its investments in new portfolio companies to (up to) $250,000 each.

The new funding round was led by Bessemer Venture Partners and Kaiser Permanente Ventures, with participation from KPCB, Mayo Clinic, Montreux Equity Partners, and Great Oaks Ventures.

“Every single one of the investors involved in our third fund shares our mission to make a massive impact in healthcare and is committed to finding the companies that will deeply transform the industry,” Rock Health said in a statement.

Rock Health says it wants to help promising new startups raise a seed round faster and help them have an easier time raising an “A” round.

The accelerator’s portfolio companies have collectively raised $207 million in just three years. The portfolio now includes 55 active companies, including Omada Health, Lantern, LiftLabs (sold to Google), Kit Check, LabDoor, Augmedix, and Wello (sold to Weight Watchers).

Rock Health says it expects to review another thousand or more companies this year and in those that follow.

While Rock Health’s headquarters are in San Francisco, thirty percent of its portfolio companies are based outside the Bay Area, including Aptible in New York City; Wellframe, Reify Health, and Podimetrics in Boston; and Kit Check in Washington DC.
