HomeBuffer

Treat home maintenance like a bill — automatically funded, calmly protected.

A homeowner builds a home profile and instantly sees a personalized monthly reserve target, auto-sweeps money into an insured maintenance fund that grows over time, and — when something breaks — taps once to dispatch a vetted, fair-priced contractor paid straight from the reserve.

System Health & Reserve screen
The wow factor

What makes people lean in

The 'System Health' dashboard that reveals the exact remaining life of every home system (water heater, HVAC, roof) and a funded reserve gauge — turning vague repair anxiety into a single, calm, fully-funded number.

Why this MVP

The case for building it

The core pain isn't knowing you should save — it's the gap between intention and a funded buffer when a water heater dies at the worst time. These screens prove the loop that no calculator or home warranty offers: estimate the true reserve target, actually hold the money in an insured fund, and spend it for you on a fair-priced repair. Showing the health dashboard plus one-tap dispatch in a polished prototype is enough to convey both the emotional relief and the defensible fintech-plus-services bundle.

The flow
