I usually say in interviews that my preferred time to join a company is at the end of stage 1 (start up) and the start of phase 2 (organizing).
Nothing makes me happier than to be told "Hey, we got this up and running and it's a mess. Now we need someone to turn this into a system that is easy to modify and maintain."

You can also be a bastard and jack up prices while cutting e.g. customer service. (Though absent new major revisions, service costs should go down.) But I'd argue we need, in tech, more of this strategy of calm wind-down than the everything-must-be-growth mindset.
