Today we've got Tom Eisenmann on the pod. He's an entrepreneurship teacher at HBS and the author of the white-hot startup book "Why Startups Fail." We had a blast talking through all the mistakes startups make and the best ways to avoid them. We also talk through how to validate when you've got big up front costs, when domain experts are important (and when they're not), and how to start the gig-economy version of the private chef.
