Theoretically Sound

Booking software for people whose workshop has wheels.

We build software for solo mobile service operators — mechanics, notaries, technicians, and every other business that drives to the customer. Our first product answers the two questions those operators juggle all day: who is this lead, and where does this job fit in my week?

What we're building

In development · piloting with a mobile e-bike repair operator in Seattle

A booking assistant with two connected halves: a conversational AI front door that answers new customers by text, asks the right qualifying questions for the operator's trade, and captures the job — and a drive-time-aware scheduler that offers each customer appointment windows on days the operator will already be nearby, so less of the workday is spent behind the windshield.

How it works

A customer texts the shop.

The assistant replies instantly, asks what the trade actually needs to know — the right questions for a bike tune are not the right questions for a notary signing — and quotes the operator's real posted prices.

The schedule does geography.

Appointment windows are proposed by where the operator's week already takes them, computed from real drive times — not just the next empty slot.

The operator stays in charge.

Every booking is a proposal until the operator confirms it with one reply. Nothing on the calendar moves without consent.
