We're building the operating system for construction — starting with the phone.
Contractors lose real money to missed calls every week. We started bhildOs to answer every one with AI that books the job — and to grow that into the single system that runs the whole company.
The job goes to whoever picks up.
Crews are on roofs and in trenches, not by the phone. Calls roll to voicemail, callers hang up and dial the next company, and the lead is gone — usually without anyone realizing it happened.
Office tools weren't built for this. Spreadsheets, group texts and sticky notes can't answer a call at 7pm or book the nearest crew.
An AI front desk that never misses.
Hope, Sammy and Luca answer 24/7, qualify the lead, and book the estimate with the closest available crew — then log a clean summary and route it into HubSpot, Google Calendar and Slack.
And when a caller wants a person, they get one. Every call is captured, AI- or human-handled, in one Intake Log.
How we build.
Answer everything
A missed call is a missed job. The bar is 100% answered, day or night.
Keep a human off-ramp
AI should help, not trap. A real person is always one request away.
Built for the field
Designed around how crews actually work — fast, mobile, no busywork.
One system of record
Start with voice, grow into the OS — without bolting on five more tools.

AI voice agents — Hope, Sammy & Luca — on every line.

From the phone to the whole company.
Voice AI + Intake Log

Estimating & Proposals
Replace the spreadsheets — line-item pricing and tiered, e-signable proposals built from each lead.
Project Management & Subcontractor App
Active jobs, field activity, check-ins and a mobile app for the crews doing the work.
Bids & Payments
Close the loop — bids, payouts and retainage in the same system of record.
