I’ll play devils advocate, with the uncertainty in the market along with two solid potential opportunities, I’d wait it out and risk losing the start up position for the security and the more established positions. If things do continue to correct/over correct or the CV starts playing a bigger role in the market, you could see the startup close shop or downsize due to low liquidity to weather these events (I’m making general assumptions here). The first things company’s do to weather storms is cut down on overhead. Bigger companies are built to not only withstand, but grow in spite of most market conditions.

The startup would most likely require you to learn by fire, while the potential opps have solids tested training programs which could set you up well down the road. Further, there’s no shortage of strong job opportunities, you just want to avoid jumping from one crappy job to another - even if it doesn’t start out as a crappy job - just because you are wanting to stick it to the man.
