Sean Gorman is currently on his 4th start-up, Zephr, working on improving smartphone location. Previously he worked on 3D mapping (acquired by Snap), mapping fibre optics infrastructure (and caught the NAS's attention as a grad student). I was recently in Colorado and got to spend a few days with Sean, at the end of which we recorded a conversation about building great teams, finding what to work on and building businesses around mapsSponsor: FeltTry out collaborative online mapping with FeltCheck out their Youtube Channel for walkthroughs of their latest featuresAbout SeanTwitterLinkedInShownotesNote: Links to books are Amazon Affiliate links.
