Before you sign, NEXUS AI scans every bid against the plan set and flags what doesn't add up.
Reads your schedule, change orders, and releases to project where cost and time are trending.
See how a bid stacks up against real market pricing for the same scope and region.
From the first profile to the final sign-off, every stage of a project lives on one connected platform. Discover the work, price it, fund it, build it, and get paid — without ever leaving NEXUS.
Every owner, GC, and sub carries a verified profile with credentials, trust score, and track record — the identity layer the whole ecosystem is built on.
Showcase finished work with photo galleries and case studies, so pros win the next job on proof — not promises.
A live board where owners post funded work and verified pros find, filter, and bid on the projects that fit their trade and region.
NEXUS AI prices any scope against real market data and cross-checks it against the plan set — a defensible number in minutes.
Upload a plan set and get quantities and line items back automatically — no more days of manual counting.
Every dollar sits in a milestone escrow vault — visible to all parties, spendable by none until the work is verified.
Funds release the minute a milestone is signed off — everyone paid straight to their wallet, no ninety-day wait.
Owners verify completion with photo-backed, AI-assisted review — the final gate that closes the loop and releases the money.

No hidden steps, no surprises. Every project follows the same transparent path — so owners, GCs, and subs always know exactly where the work and the money stand.
The owner publishes the project to the board and deposits the budget into a milestone escrow vault — visible to all, spendable by none.
GCs bid whole jobs, subs bid by trade. Every bid is transparent, comparable, and AI-leveled against a defensible estimate.
The owner awards the job. Crews build each milestone and submit completion photos for AI-assisted review.
Once verified, the owner signs off and funds release in minutes as Nexus Credits — everyone paid, no ninety-day wait.
NEXUS isn't a marketplace that takes a cut and walks away. It's an institution with one rulebook, one ledger, and one promise: the process stays open and the money stays safe for owners, GCs, and subs alike.
Bids, milestones, and fund status live on one shared ledger the parties can see — no black boxes, no hidden markups.
The same escrow, verification, and dispute process applies to every project — owners, GCs, and subs play by identical rules.
Owners keep control of releases; contractors are guaranteed the work is funded. Money stays locked until the job is verified.
Faster payouts, fewer disputes, and repeat work reward every side — a platform built so the whole chain wins together.
