Nothing goes out until you approve it.

The rule every agent follows

The crew prepares the work. Your people approve every price, signature, payment and send.

How every BuildWithBNZ agent worksAgents prepare. People decide.

Built from real contractor workflows inside BNZ Builders, New York.

Amanda

On our side

Head of Marketing, Creative Production & Sales Research

Adam

On our side

Leads software engineering and cybersecurity for the AI team, working with Adam, our human developer.

Software releases need Bilal's explicit approval first.

The AI agent Adam and Adam, our human developer, are two different team members.

You

Owner · the final say

You approve every price, signature, payment and send. The crew never makes the owner's decision.

See each agent's limits and human partner →

No made-up numbers. Every answer the crew gives you carries a label, so you can see what's been checked and what hasn't.

See how it works →

  • Sara

    Never touches a price. Any change goes back to the estimator.

  • Taylor

    A human estimator approves every price before it goes out.

  • Sara

    Never calls a bid submitted without proof it arrived.

  • Taylor

    Sara checks the bid, and nothing is submitted until you say send.

  • Emma

    Your accountant or CPA reviews payroll and the books.

  • Kyle

    Every design option goes to Taylor for quantities and cost before a client sees it.

  • Richard

    Legal interpretations and consequential decisions go to human legal review.

  • Sara

    Never fixes a problem silently. It comes to you.

  • You approve every sendEmails, prices, signatures and payments wait for you.

  • Every answer labeledVerified, reported or unknown. Never a guess.
  • A person behind every agentEach agent works with a named person on our team.

Questions contractors ask first.

All questions →

What does it cost?

It starts with a Project Review: a real call about one real project. Then we send you the scope and one set price for that project, in writing. Price moves only if scope moves.

Do I have to change my software?

No. The crew works inside the email, files and calendar you already use. Nothing is moved or replaced, and it starts with read access.

Does the AI send anything without me?

No. Every email, price, signature and payment waits for your yes. The crew drafts. You decide.

Is this for my company?

It's built for general contractors, remodelers and custom builders, specialty contractors, and GCs bidding public work. Not sure? Call 646-281-8368.

Run the company. Keep every decision.
