Plenty of people outside of the Valley are doing stuff in healthcare, especially in SoCal, Ohio/Pittsburg, DC/Baltimore, and Miami. However, most of what they do is not tech-related, so it is not covered on a tech-focuses site like HN.

Technology is not the magical solution to all of the world's problems. In many cases, and especially in healthcare, simple solutions (such as washing hands, using checklists prior to surgeries, or improving fitness levels among the general population by even a fraction of a percent) can have outsized impacts on the quality of medical care and associated costs.

>Preventive healthcare aided by the use of mobile health monitors that automatically track and log personal health metrics is another big opportunity and will likely be the biggest revolution in healthcare in over a century if it takes hold.

Not likely; we're about as close to developing automatic mobile health monitors as we are to developing Cylons. The problem seems easy in the abstract, but the specifics of something as simple as food monitoring or exercise monitoring is something that we haven't even gotten close to figuring out yet, despite hundreds of millions spent by many, many very motivated market participants.
