Do you own the customer, or does a gatekeeper stand between you and revenue?
E — Entry
How hard is this to copy once it works? A rival's existence isn't the question — the durability of their advantage is.
N — Need
Is demand proven with money rather than vibes?
T — Time
Can income detach from your hours, or did you buy yourself a job?
S — Scale
How far does it reach without linear cost?
Scored on the evidence below, against CENTS as we've adapted it plus a Buffett-style moat reading of every rival — the same referee for every idea, including the ones we generate ourselves. The verdict follows the arithmetic: we never relabel a score to make it read better, and the weakest commandment is always named. The exact rubric stays in-house so the scale can't be written for.
02 — The pace test — $1M/yr
At $299/mo (assumed category price), you need 279 subscribers for a $1M/yr pace.
Nearest tracked rivals on that curve:

$0k 0%
Part II — The Evidence the receipts, good and bad
03 — Rival scan — corpus tracks 1 similar, 1 stalled under $2k MRR
Cannot tell whether niche marketplace operators will pay before an audit forces them.
No data on Stripe's roadmap for native facilitator tax and 1099 coverage.
ZebraSnap's $0 MRR may reflect a different product, not this category's ceiling.
Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-09-20.
08 — The wedge & the next step
Marketplaces too small for Avalara/Tipalti but past Stripe's defaults — one engine for facilitator nexus plus 1099-K/NEC.
Cheapest next step: Cold-DM 15 niche marketplace founders; ask who filed their last 1099 batch and what it cost.
