So I haven't worked at a hardware start-up but it seemed pretty difficult even before these companies to raise funding versus a pure software play. I'm not necessarily convinced this makes it easier or harder. Is there a specific reason you think it will be harder now?
Also, for what it's worth, Fitbit and GoPro are still going. I'm convinced Fitbit can get back on the growth curve as long as they can get a new product out the door that consumers want. Tall order for sure but I don't count them as a failure yet.
GoPro want to move to doing software more so than hardware. Considering their software has always considered to be lackluster to borderline terrible I'm less convinced they will turn it around but also not yet willing to say they're a failure.
