Public verdict

Vendor Live

Big market, real pain, but you need proof of repeat usage and reliable data to escape tar-pit risk.

MAYBE

/ 100

This is a real market, but without proof of repeat usage and reliable live data, it’s just a hard local ops project that may never become a product.

Green flags

Real, concrete pain: buyers miss vendors and vendors miss sales because timing is invisible.
Founder-market fit is plausible via prior experience with RetailBook and informal businesses.
The Wizard-of-Oz + WhatsApp wedge is an appropriate validation strategy for this messy market.
The market is genuinely large if trust and repeat usage materialize.
The problem has a clear behavioral loop: timely alerts can drive repeat daily usage if the product works.

Red flags

This could be a solution in search of a problem if users do not change behavior to check alerts repeatedly.
Live data reliability is fragile; one bad prediction can kill trust quickly.
Cold start is brutal because you need dense vendor supply and buyer demand in the same micro-market.
The moat is thin early: maps, WhatsApp groups, habits, and local memory are obvious substitutes.
This has tar-pit risk from heavy manual ops, local bootstrapping, and weak scalability.
Subscription economics look uncertain for vendors with limited budgets.
No proof yet that buyers will retain or vendors will keep updating status daily.
