Get out before the pressure mounts. Speaking from experience, the stress that leads up to the bust is on an exponential curve.

Worse than a bust, many SAAS startups become a regular small business with a few big clients but everyone is disgruntled because the dream of a big payday died. There's nothing wrong with a small SAAS business as long as it doesn't start with "shoot for the moon" fantasies and VC cash. This kind of "exit" will hurt your career. It's better for the entire company to fail. Your future interviewers will not see this kind of business favorably.

You could ride this out until it busts but you could be playing a game of musical chairs. If the company busts due to a problem in the greater economy, then you're stuck trying to land a job before the music stops.

Right now you have the opportunity to turn a well-paid job without stability into an equivalent or better paying job with stability. It is much harder to find a job when you don't have one. Our field is full of pretenders that are out of work. That's why people fail FizzBuzz. You risk being lumped into this category if you're looking for a job after your company busts (or the economy is down.)
