We build one thing, carefully.
An employee that answers your phone, writes down what happened, and remembers the customer next time.
An AI employee for your phone line, plus the work around it.
Service businesses in the US where a missed call is a lost job.
Self-serve, printed prices, month to month.
A person. Sometimes our own AI — and it says so.
Four rules, enforced in code.
You can check every one of these against the product.
A call never dead-ends.
Every finished call produces something — a ticket or an appointment request — even when the AI never reaches for a tool. It is a guarantee in the pipeline, not a prompt we hope holds.
We fail closed on money.
Gating checks fail open so a paying customer is never locked out. Billing writes fail closed so nothing is ever guessed. When those two conflict, money loses.
Everything can happen twice.
Webhooks retry. Networks repeat themselves. Every write path is built to be run again without doing damage — that is why a retried call does not create two appointments.
We say what isn't built.
Channels in beta are labelled beta. Certifications we don't hold are named on the security page. We removed compliance claims from this site that we could not stand behind.
