The IOLTA Detective: Finding the $275 Clio Can't Explain
California now bills attorneys $5,000 to $10,000 for CTAPP trust audits, and 83% of pilot firms failed three-way reconciliation. Clio bundles the checkbox. The forensic cleanup layer is still empty.
The Microdrama Ad Studio: $60K MRR From Romance Backlists
China industrialized AI vertical drama, ReelShort proved paid creative sells it, BookTok moved 50 million books, and top romance authors spend $4,500 a month on ads. The bridge is unbuilt.

Retailers took back $850 billion in 2025, yet no Shopify returns app can say whether a $100 sweater is worth retrieving. A per-SKU keep-it refund engine for apparel brands.
FamilyMart's ¥20 Billion Sock Business, Rebuilt for U.S. Airport Hotels
FamilyMart moves ¥20 billion a year in convenience-store basics. U.S. airport hotels host the same delayed-bag traveler with nothing on the shelf, and DOT makes the purchase reimbursable.
The Anti-Storage Business: $24K a Month Emptying Units Nobody Opens
Self-storage's $40 billion model runs on deferred decisions: 46% of Extra Space tenants have paid two-plus years. The storage unit cleanout business sits on the other side of that indecision.

Target Beauty Studio Just Created a $50K/Month Field-Ops Gap
Target Beauty Studio put 90 brands in 611 stores overnight. Most have no U.S. field team to check the shelves. The retail-execution service that fills that gap.
The $165 Billion Pet Shelf Google Can't See
Uber Direct solved the courier problem for independent pet stores. Nobody solved local inventory you can search, reserve and trust for tonight. A Philadelphia wedge into same-day pet retail.
The $500,000 Water Bill: Auditing Laundromat Deals by the Gallon
A cash laundromat can argue with its P&L. Its water meter is harder to argue with. Acquisition diligence still runs on broker spreadsheets while the median laundromat listing asks $500,000.
FamilyMart's Labor Math, Shrunk to a 7-Store Chain
FamilyMart is re-engineering labor across 16,500 stores from predicted demand. Multi-location grocers and pet retailers on Square still schedule by habit. A Square-first labor planning layer fits between them.

Meta sold 7 million camera glasses in 2025. Courts, nightclubs, and casinos are banning them with no way to check. That enforcement gap is a subscription business.

The $17.99 Submarine Game With No 3D Submarine
Silent Shark hit 98% positive on Steam, built solo in six months with Codex. The edge was what its developer cut. Every bloated simulator genre hides a loop like it.
The Ghost Paywall Lab: $50K MRR From Newsletter Experiments

The $240 Printer That Turns Coffee Cups Into Media
