*'''[[Digital Medicine]]''': Buzzword-like category to keep track of companies that are creating software interventions that may qualify as actual clinical interventions (diagnostic, therapeutic) one day.
*'''[[Insurance]]''': Startups that are disrupting the traditional health insurance carrier industry, using new approaches like digital tools, prevention focus, etc.
*'''[[Hardware Platforms]]''': These are (were) the players putting forth physical computing devices with healthcare focus (eg. built to withstand bumps, disinfection, spills etc). This category was fascinating in early 2000's, but now mostly lifeless. Preserved only for bemusement and posterity.
