Shirtlist

Payback period, asking price vs category median multiple, and 30-day profit margin.

30-day MRR delta, with a small bonus when historical snapshots confirm a sustained climb.

Revenue per visitor, customer count, plus live-site UX signals (pricing reachability, core pages, copyright freshness).

AI-disruption risk, presence on review platforms (G2, ProductHunt, AppSumo…), penalty when built on no-code rails.

Diversity of marketing channels, Merchant-of-Record status, cofounder count. Solo founders and no-code stacks get docked.

Listing freshness, payment provider trust, business age, customer concentration. Higher score = less risky.

Structured market read across TAM, saturation, 3-year trend, and hype cycle, blended with our category momentum signal.
