The $39 Vet Visit Kit Inside a $158 Billion Pet Market
Pet owners now run rapamycin and peptides on aging dogs while the FDA logs thousands of Librela adverse reports. Senior dog care still lacks a record clinics can use.

The $129 Shelf: GLP-1's Missing Medicine Cabinet
Ten million Americans store Ozempic and Zepbound pens next to the milk. Pharma made the drug, Whirlpool made the fridge, and nobody designed the six inches in between.

Astrology and tarot now rank among the ten most popular consumer AI uses. CHANI clears $405K/month, Nebula $516K. The conversational, journaling-first lane is still open.
The 570-Hour Estate Job Nobody's Productized Yet
The U.S. has no equivalent to the UK's Settld. A state-focused aftercare portal for independent funeral homes and estate attorneys could reach $10–20K MRR with 20 pilot locations.
GLP-1's Missing Workflow: A $20K MRR Fiber Ramp for Clinics
GLP-1 prescriptions doubled in 18 months, but most patients get no fiber or symptom guidance between visits. A narrow clinic workflow tool is the opening no consumer tracker owns. ---
