-Founders weren't always honest (eg. # of paying customers and QA'd workflows, feedback given in one on ones, etc.).
-Founders didn't figure out PMF or ICP before handing off sales to other employees.
-Impetuousness (e.g. firing people without warning, losing deals because of timelines that weren't met/not QA'd, badmouthing employees who left the company).
-Founders are immature/poor leaders. Even accounting for founders' age (~21 and ~23) leadership/management was unimpressive, callous, and often felt reactive instead of proactive. Didn't feel like they care about their employees.
-Impressive investors who were pretty much useless from an intro/BD perspective. Buzzy names are neat, but people who will actually use the product or make intros are more important IMO.
