Pros
None. This isn't hyperbole. There is no good reason to take a job in payrails.
Cons
Leadership culture is defined by the co-founders - no transparency, no empathy, no trust. Employees are there to be used and discarded according to their whims, which change weekly. COO often mistakes volume for motivation - if he just shouts loud enough, that'll fix the problem, right?
Vision - companies goals change monthly, whatever new thing happens to catch the co-founders eyes, that the flavour of the month. The whole company has to orientate around it, before the COO and CEO realise they can't do it, and pivot again. If it leaves carnage in its wake, they'll blame the employees, because it will never be their fault.
Complete and total lack of leadership. CEO may as well live on the moon, COO can't be trusted. Will say one thing and do another. Zero consistency, and zero regard for employee impact.
Culture of leadership self obessision. This company is built on the ego's of two men. It's all they care about.
Lack of support and systems. Employees are given nothing to make them successful, and when things break, which they do all the time, the CEO and COO seek to blame the employees, not the lack of systems.
Cheap, cheap company. This company tries to cut corners on everything, and it shows in its product, how it treats its employees and its customers.
Product - mostly vapourware, and what little actually exists is both simultaneously generic and impossible to implement. People would rather quit than implement this product
Trajectory. It has one, just not the one they'd like.
