There are some terrible YC companies but we really only talk about the successful ones and the process to get to successful is a messy struggle. A good YC company would be glad you provided feedback they can use to make the process better. Other startups YC or not can learn. Stories like yours are common and we all can relate. Honestly it doesn't sound all that bad, the CTO is letting you choose the stack and run with it. Distracted CTOs are much better than owners who think they are programmers (who get drunk and commit changes at 2am that break production). Hiring and firing/quiting is common in a startup. You need to build a team that fits together and getting that right is hard.. things usually stabilize. Is this your first startup?
