THE EVIDENCE ENGINE FOR PAID WORK
Do the work. Prove it.™
Let the evidence decide.
An AI referee judges the work against criteria sealed before it starts. The verdict lands on a record anyone can re-check — and payment follows it.

HOW IT WORKS
One loop from proposal to proven
Contract tool, project tool, payment tool — and hope. Northn is the loop that connects them.
Scope, milestones and acceptance criteria are fixed before any work starts — and the first milestone is funded.
- AI drafts the statement of work from your brief
- Every criterion names an observable outcome and its proof
- Acceptance seals the criteria; milestone one is funded with our escrow partner
STATEMENT OF WORK
DRAFTED FROM YOUR BRIEFPayments API — Sprint 2
4 milestones · 19 acceptance criteria · $48,000
- M1Environments & auth4 criteria
- M2Payments API7 criteria
- M3Reconciliation5 criteria
- M4Go-live & handoff3 criteria
Criteria are fixed here, before any evidence exists. Anything later is a change order; the original stays sealed.
If a client pushes back, you're not arguing. You're pointing at the record you both watched build.
BUILT FOR YOUR CRAFT
One engine, every craft
Criteria, evidence and the referee are shared. Each craft gets its own evidence moments.

WHO SETS THE STANDARD
Whoever pays sets the standard
One engine — criteria, evidence, a referee (the AI that judges the demo), and the record, with escrow through a regulated partner. Criteria are agreed and sealed before work starts; whoever funds the milestone sets them, and both sides see the same record.
Firms set it for their clients
Dev shops, agencies and studios run verified delivery under their own brand.
That's this page
THE FLIPBuyers set it for their vendors
One evidence standard as the price of admission — and comparable vendor scorecards.
For companies that buy work
THE PLATFORMPlatforms embed it
Rails that move money on conditions send a statement of work and get back a verdict per condition.
For platforms and rails
Northn is not a marketplace. You bring the client, set the terms, and keep the relationship.
HOW A MARKETPLACE WIRES IT
Every dollar, every approval, every relationship routes through the middle — and the middle takes a cut of all of it.
HOW NORTHN WIRES IT
direct contract · your rates · your name on the work
The relationship stays direct. Northn is the foundation it stands on — proof and protection working for both sides, on a record both sides can check.
PROTECTION
The engine judges. Regulated escrow moves the money.
Northn decides when a milestone has earned release. Our escrow partner — a regulated, licensed institution — holds and moves the funds. Never Northn's balance sheet.
Where the money lives — the security reviewWITH NORTHN
ONE ENGINEevidence, and the record
- Criteria sealed and evidence judged before a dollar moves
- Funds held by our escrow partner, a regulated institution — never on Northn's books
- Release follows the verdict: approval, a verified event, or a ruling

THE RECORD, ON ITS OWN
Some work isn't paid by the milestone. It still has to be proven.
Same sealed record, no escrow — and it follows the firm and the person who did the work.

THE COMPANY BEHIND NORTHN
We were the vendor first.
We built Northn because we lived the problem: years of demos debated instead of verified, invoices chased instead of released. It grew out of Northern Node's own client-delivery practice.
Northern Node still builds software, staffs teams, and does security work — delivered on the same record you've just read about. Scoped and priced separately, when you want it.
BUILD
Software, built on the record
Product and platform engineering by our own teams. Milestones sealed before the first commit, paid on approval.

When anyone can generate convincing work, verification is the scarce good. Northn is the record.
