Google-backed Zephyr Health helping device and drug companies hit sales targets with Big Data

San Francisco's Zephyr Health is attracting lots of attention thanks to its software for ranking doctors' influence on others, a valuable metric when deciding whom the sales team should visit, or whom to invite to a conference. And it has branched into the device world. Along with Big Pharma players Amgen ($AMGN) and GlaxoSmithKline ($GSK), the company counts Stryker ($SYK) as one of its customers.
