First Fitbit files IPO papers, then MindBody (software for yoga studios, etc.) follows suit last week. So who’s next? The good folks over at Rock Health wanted to know, so they polled a group of 43 digital health investors to find out.

The investors thought that if the market has an appetite for fitness wearables, then perhaps Jawbone should be the next to file papers. If that were to happen, we would learn a lot more about Jawbone’s books, which past reports have said contain some unsavory aspects. The company’s products, in general, have been well received.

Then there’s perennial favorite Practice Fusion, which offers a free (and ad-based) electronic patient records system and a medical information research platform to physicians. The San Francisco-based startup has been has been trying to raise its visibility for the public markets for some time now; whether it has the balance sheet that investors would like is yet to be seen.

Then there’s Salt Lake City-based Health Catalyst, which creates data warehouses for clinics and hospitals using data from the providers’ financial and clinical records systems. From the data, Health Catalyst and its customers work together to create clinically effective and financially efficient care protocols.

Here’s the whole list of IPO candidates:

unnamedThe smart money is probably on Health Catalyst, which provides an essential service to health providers in the age of value-based care. The need for warehousing and analytics will not go away; instead a sort of analytics platform arms race will likely shape up. Fitness trackers, on the other hand, are threatened by the Apple Watch and are often thrown into a drawer after a few weeks. Computer-based patient records are seen as an unpleasant reality by physicians, not a source of surprise and delight.
