Regret joining a startup

I was working at a mid-sized company, fully remote, with great pay. Last year I decided to join a startup working in AI and regretted joining it.

I thought at least I would get to work on good tech, but this company is going nowhere. I'm on the lookout for new opportunities, I still like the ownership I get with startups but given the AI space is soo competitive now I'd rather join a big company.

I applied to a bunch last week, still waiting to hear back from any of them. Feels like I made a big mistake, should have just stayed comfortable lol.
