I've had the exact same experience. Throw in a large dose of "no repeat customers" due to us prioritizing Feature A for Potential Customer B over fixing existing gaps that affected actual customers, and it was a never-ending parade of haphazardly created, bug-riddled new features that never got improved.

Made every single day a death march and a company that survives purely on the sunk cost fallacy on the part of the investors. They've already dropped $MILLIONS into building this thing, and the CEO swears that this next big deal will be what finally pushes the company into the stratosphere. As miserable as it was to work there, I'm honestly impressed they're able to keep that zombie moving.
