500 Startups, a San Francisco-based accelerator and investor, has announced its 18th cohort, a group of 46 companies total which includes, for the first time, a digital health track of eight startups.

Despite the name, 500 startups has more than 1,500 startups in its network that have either been through the accelerator or received Series A funding from the group. This does include some digital health companies already: BetterDoctor, uBiome, Fitocracy, and Neutun to name a few.

The acclerator gives $100,000, office space, and access to mentors and experts in a 4-month session in exchange for 5 percent equity. Here's the eight digital health companies joining the ranks of 500 Startups.
