IC: Product Launches
New releases, app store shifts, and product feedback that show market traction.

Couch-to-5K for Cash: Build the Side Hustle OS
The median side hustler earns $200 a month. The average earns $885. That execution gap is a SaaS product waiting to be built.
AI Workflow Receipts for Small Agencies
Provenance infrastructure is getting funded at scale but nobody is building the agency-facing workflow layer — a $200K year-one opportunity hiding in plain sight.
"Ghost Kitchen" for Crafts
Millions of laser cutters sit idle in garages while Etsy sellers lose sales to slow shipping — the coordination layer between them is wide open.

NotebookLM proved professionals will listen to their documents. Nobody owns the vertical briefing format for law or finance — and the pricing anchors to $800/hour time saved.
Cross-Border Vibe Arbitrage
UK social commerce trends consistently preview U.S. demand by months — a cross-market intelligence product turns that lag into operator-grade deal flow.
Calm for Quitters
Habit apps punish failure. A maintenance-first protocol targeting burnout, ADHD, and low-energy weeks could own the gap Calm proved exists.
Retro Experience Agency ($24K MRR)
Gen Z is sharing through group chats, not feeds — and brands will pay premium retainer rates for owned retro destinations that convert.
Comfort API
