When a building company asks us about voice AI agents, the first question we put back is the same one every time: which part of your week, if it disappeared, would change how you feel on a Friday? We start the build from that answer.

Field notes
What years of building for building companies taught us.
- Builders run multiple sites at once, and the paperwork behind each one grows faster than anyone has time to manage.
- Variations, supplier orders, and client updates are the admin layer that determines whether a build stays on schedule.
How we build voice AI agents for building companies.
We scope narrow, ship a working pilot, then harden it into production. The first slice is the highest-leverage workflow for a building company business, so value lands before the build is finished. AI phone agents.

Questions
FAQ
How long does voice AI agents take to ship for building companies?
We aim for a working pilot inside 4-6 weeks – narrow scope, real building companies data, measurable outcome. From there it's another 6-8 weeks of hardening before you'd consider it production. Full rollouts (multiple sites, multiple teams) typically land in 3-4 months.
How do you price voice AI agents engagements?
Fixed-scope pilots first, then either project pricing or a small monthly retainer for the ongoing work. No long lock-ins, no 18-month black-box deals. Most building companies are surprised how small the first cheque is.
Has this actually shipped for a real building company?
Yes. 42% of after-hours calls now booked without human input. We'll share comparable engagements on the call.
Who owns the code and the model setup?
You do, on delivery. We deploy voice AI agents into your own cloud account where possible, with the model setup, prompts, evals and integration code all checked into a repo you own. Vapi sits in your account too – we don't operate it from ours.
