Medtown, which invests in medical devices, biotech and health IT entrepreneurs, delivers two critical startup ingredients — capital and brainpower. The financial company syndicates up to $5 million in individual deals. It also installs a “temporary S.W.A.T. team” of operators who help the founder — typically a Ph.D. or scientist — take the promising technology to market. The result: startups are more likely to achieve development milestones, secure later-stage funding and become sustainable.
