CTO is a bad manager. Unreasonable demands, rejects ideas, doesn't listen to advice from people with experience.
First time I had a manager that expected me to work when I'm sick.
A manager that thought picking up my kids from school was optional and asked "can't your partner do it?"
CEO is cut-throat professional manipulator.
The entire company is a fraud - they market themselves as AI company, but end of the day it's just false. The AI is not ready and they have an army of Data Analysts looking at the numbers on some messy dedicated servers.
Salary very low. %30 below market. they use the fact they appear as an innovative startup to lower your ask.
