Pros
It's a deep tech startup.
Cons
Culture of overpromising/underdelivering. Poor ops. The business model is inherently dependent on the company's capacity to deliver good enough outcomes at a significantly lower cost than the leaders (citrine or local solutions that are favored for reasons of data protection).
CEO is problematic - acted irresponsibly, too much self-permission, belittled an employee when felt insecure, no shows to meetings with no justification, and generally speaking is mercurial and double faced. Professionalism is too often performative, and runs away from accountability by overusing arguments of being busy. I don't understand why this issue hasn't surfaced already.
CTO is the smart one but doesn't want to run the company.
