fitbitFitness band market leader Fitbit has relied on The BlueShirt Group for financial communications support through its successful June 17 initial public offering.

The San Francisco-based company, which works with Olson Engage, FleishmanHillard and Burson-Marsteller on the PR front, surpassed expectations with its New York Stock Exchange debut, raising more than $840M for a valuation of $7.6B. Forbes noted the 52% first-day stock surge was among the 10 biggest "pops" of the year. And the Wall Street Journal said the company managed an unusual feat for hot IPOs: staying above its debut price for a week.

The solid debut came after rival Jawbone sued Fitbit just weeks before the IPO, alleging Fitbit poached employees and trade secrets.

BlueShirt Group managing director Peter Salkowski, former head of IR for Dreamworks Animation, heads the Fitbit account for the firm.

Recode's Lauren Goode managed to knock Fitbit CEO James Park off message briefly in New York this week as he admitted to dining on Shake Shack and a street hot dog while in the Big Apple. A PR staffer interjected to note that the CEO of the fitness company "eats mostly healthy food."
