Tom's been live since January 5th. Field notes from the ongoing experiment.
Tom went live January 5th, 2026 across three family businesses โ Oven Repairs Perth, Sky Signal WA, and Perth Services. Six weeks in. Still standing. Sharon still hasn't reached for the hammer.
Under the hood
Tom is a voice AI agent built on ElevenLabs Conversational AI, connected to a real phone number via Twilio. The prompt engineering took 150+ versions across 6 weeks of live calls. No SaaS subscription. No monthly platform fee. Built from scratch by a tradie who missed one too many calls while elbow-deep in a switchboard. Full build guide is free โ start here.
