“We continue to grow and are profitable, however not at the pace previously expected,” Fitbit Co-Founder and CEO James Park said. “We are focused on improving the utility of our products and integrating more deeply into the healthcare ecosystem and believe we can leverage our brand and community to unlock new avenues and adjacencies of growth.”
