This retrospective by the founder of Pebble is a must-read for anyone who contemplates starting or joining a startup. I’ve been through 5 (or more depending on how you count them), with more failures than successes and I have to say that I’ve learned MORE from the failures than the successes.
Yes, I backed Pebble on Kickstarter and still have the original laying around here somewhere in my museum or Blackberries, Amigas, Palms, etc. It was a valiant effort and defined an industry. https://medium.com/@ericmigi/why-pebble-failed-d7be937c6232
