What is this?
An appointment reminder tool helps one kind of business stop chasing every booking by hand. Start with a narrow niche such as salons or tutors, look for public signs that missed appointments really hurt, check existing tools and map one simple flow: reminder sent, customer confirms or cancels, business sees status. Build a consent-safe demo, run it with three pilot businesses and ask one to pay for continued use.
Why it may work
- Missed appointments cost businesses real money.
- A tiny tool can solve one clear job.
