Pet spending hit $158B in 2025, yet 52% of owners skip recommended care. No one decodes the estimate at the moment of panic — that silence is the business.

Achilles Pre-Hab for Pickleball's 55+ Players ($1M Niche)
Pickleball injuries jumped 91% in two years, concentrated in the 60-to-79 age group. A digital pre-hab program built around Achilles, calf, and fall-prevention protocols is the narrow wedge nobody has claimed.
