Vanderbilt MBA student Baxter Webb's startup, MEDarchon, will be among 100 businesses featured at a boot camp at Stanford University, which will include talks led by people behind companies including Google and TiVo. In addition to the feedback, fortunate participants could leave with leads on potential sources of funding. MEDarchon is going after a share of the estimated $20 billion spent nationwide each year to prevent medical errors, plus a $2 billion-a-year medical communications market. It's developing an electronic paging system with cloud-based technology to improve communication among doctors, nurses and others, and reduce errors at hospitals and clinics.
