Did you have previous experience in a similar stage company? I had a lot and I'm almost feeling like "I've been through this stuff before" and that demotivates me. But I will accept the argument that learning (by teaching) never stops. I do like the team. The product? well, it's challenging but I'm not using it. I don't have stuff (at least technical) to learn unless they decide that we need to start moving quickly and not be stuck in legacy code. They started doing microservices with 0% testing and I'm still trying to teach them about contract-driven APIs
