Digital health funding reached $5.8 billion in 2015, according to CB Insights. The research firm explained that this was just a slight increase from its 2014 total, which is in stark contrast to the significant growth from 2013 to 2014. Funding grew from $2.3 billion in 2013 to $5.1 billion in 2014.

Some of the larger deals that CBI tracked in 2015 included ZocDoc’s $130 million, 23andMe’s $150 million, and $394 million for Guahao, a China-based digital health company that develops medical apps for patients and doctors.

CB Insights also added that there was a 20.6 percent increase in the number of deals year over year -- 900 in 2015. About 36 percent of them were seed and angel rounds, while 15 percent were series A, 7 percent were series B, and 4 percent were series C. More than 1,000 investment firms and individuals made at least one equity investment in a digital health company. In 2010, according to CB Insights, just 234 did.

This year some of the more active investors included Y Combinator, Dreamit Ventures, Rock Health, Qualcomm Ventures, and Ben Franklin Technology Partners. Both Y Combinator and Dreamit Ventures invested in more than 10 digital health companies last year.

Last month, Rock Health released its 2015 Year in Review report, which found venture funding in 2015 had reached $4.3 billion, right on track with 2014. Rock Health only included funding deals above $2 million and their data was as of December 8th.

Another report, this one from StartUp Health, said digital health funding was down from 2014. StartUp Health reported that funding hit $5.8 billion as of mid December, compared with $7 billion in 2014.
