Pros
You get to work, in part, with some academic royalty in the field of behavioral economics. Paying work in this field is pretty difficult to get so that alone is an exciting plus. Work is fast paced and you'll get to touch many types of companies in the healthcare space. You can learn a lot here but there's definitely a ceiling where you wont advance past, won't learn anything more, and should probably get out.
Cons
This "startup" never really got its feet off the ground. Probably because it doesn't have any "IP"; It's based in nothing special, just some studies anyone can read online and an association with some top tier academic names. CEO is an ex big 3 consultant and can be pretty poisonous - sucking the life out of a room before you can blink. Sharing that brittle temper with employees made some folks kinda haunted/scared, and other folks just rolled with it. Smart but not an especially strong manager, and very rooted in "the way things should be done", even though she is desperate to differentiate. She had a habit of "bending" the truth on its head in sales decks, which always rubbed me wrong but I understand it's common in sales. While you can learn a lot there, it will only be about consulting (not marketing or much else) and it will be only a single person's take on consulting. When I was let go she emptied the office of the 5 other employees and kinda shushed me out the door. Felt weird since we were an office of 6, I had been there longer than anyone save her, and she seemed to think we were leaving on "good terms". One of the most shaming experiences of my life.
