Venture funds are pouring into digital health, with more than $2.3 billion of investments in the sector during the first half of the year — already surpassing the 2013 total.
The eight biggest deals made up a third of the sector’s funding this year, according to the mid-year report by Rock Health, a San Francisco incubator and fund. Those deals included: NantHealth ($135 million), Flatiron Health ($130 million), Alignment Healthcare ($125 million), Proteus ($120 million), MedHOK ($78 million), Lumeris ($71 million), Zenefits ($67 million) and Doximity ($54 million).
Digital health is a loose term that describes companies bringing information technology to the healthcare industry to lower costs, boost efficiency and improve diagnostics and treatments.
Rock Health said the most active investors in the first half included Qualcomm Ventures, Andreessen Horowitz, Bessemer Venture Partners, Emergence Capital, Google Ventures, Matrix Partners and Venrock.
Things weren’t as vigorous on the public market side, where Rock Health’s index of 18 companies underperformed the S&P 500. While the S&P 500 is up about 6 percent year to date, the digital health index is down more than 10 percent.
