Construction procurement,
reimagined, for today

Turn materials procurement from a relationship-driven black box into a real-time AI-powered marketplace — transparency, verification, and competitive bidding built in from day one.

Why CityBuild Exists

Hundreds of billions goes into construction yearly, most of it unautomated.

Every other industry digitized and automated. Construction still runs on phone calls and gut instinct — procurement decided by who you know, not what the market offers.

The result is predictable: cost overruns, payment risk at every step, and zero transparency for anyone in the chain. We built CityBuild to fix that — from the ground up.

The CityBuild Fix

We rebuilt procurement from scratch.

AI reads plans instantly

GPU-native engines parse every plan the moment it's filed, generating trade-specific material lists automatically.

Real-time price transparency

Live marketplace pricing with thousands of competing bids. No more relationship black boxes or price opacity.

Funding verified upfront

100% of project funding confirmed before any subcontractor lifts a tool or moves a dollar.

Zero manual procurement

Bidding runs 24/7. Material lists are auto-generated. Your team focuses entirely on building.

Locked pricing, guaranteed payment

Once the price is set, it's locked. Payment secured from verified funding — every time, no exceptions.

How It Works

From permit filing to final payment, one platform handles every step, automatically.

CityBuild's AI reads your project plans the moment a permit is filed — generating material lists, routing bids to verified vendors, and tracking every dollar through to final payment. No manual handoffs. No chasing invoices.
