“one that I really like is time to first sale which is basically how long does it take for a mentor uh that joins Mentor Crews to get their first Mente uh and that's like a really crucial metric... you have liquidity so how much of you or how many of our mentors currently work with a Mente how much of our supply is actually on use right now”

Track marketplace-specific metrics SaaS founders ignore: time-to-first-sale, liquidity, GMV

MRR alone hides the structural health of a marketplace. Add: (1) time-to-first-sale per supplier — how fast new mentors get booked; (2) liquidity — % of supply actively earning right now; (3) GMV — total transaction volume flowing through, not just your cut; (4) demand:supply ratio. These are the leading indicators of marketplace health. If time-to-first-sale rises, your supply is outpacing demand and you need to brake supply onboarding.
