Jawbone Inc. is set to be a much smaller company, according to reports that it’s ending production of its fitness trackers and seeking buyers for its speaker business. [...] Tech Insider reported that Jawbone has stopped production of its Up fitness trackers and sold its remaining inventory to a third-party reseller. Jawbone and Fitbit Inc., pioneers in activity trackers, have struggled to grow as competition picks up in the wearable-technology market, an industry that tech giants, including Apple and Google, have set their sights on. Jawbone started early and was strong in the speaker and fitness-tracker markets, but suffered as it was undercut by cheaper competitors, and the products became easily replicated, said Chris Jones, chief analyst at Canalys. Jawbone’s fitness trackers suffered from competition at both ends — cheaper Chinese options and expensive, but more engaging smartwatches.
