For a while now I've been keeping a running list of the health technology startups I come across sorted by the category they compete in. There are about 100 companies on the list. I've moved the list over to an open Hackpad that you can find here. Hopefully this list will help people better understand what's happening in the industry, research competitors and even discover new investment and job opportunities.
I've left the Hackpad open so that anyone can add a company or category. Please add any that I've missed (I'm sure there are a lot).
As we move to the "Post-EHR" world where innovation is led by patient and provider needs as opposed to government mandates, I'm sure we'll see even more startups and categories emerge -- so I expect this list to get a lot longer.
