Now live, The engineering inspection standard

Hire vetted inspectors. Any engineering field.
Escrow holds every dollar.

From pipelines and pressure vessels to bridges, switchgear, rotating equipment, and process plants, five engineering disciplines, dispatched in minutes, audited to the byte, and paid only on a signed, tamper-proof report.

How it works

From scope to signature in three steps.

We engineered NEXPEC so an admin never sees a job in limbo and an inspector never invoices a no-show.

01
Post the scope
Post an inspection scope, or a full RFQ to source equipment, materials and labs across any discipline (API, ASME, ACI, NETA, OSHA PSM, AWS). Vetted vendors bid price-blind, and our spec assistant suggests requirements from similar jobs.
02
Match in minutes
Pick an inspector or award a vendor, escrow funds the moment both parties sign, and on award NEXPEC auto-spawns the matching source/FAT inspection. Coordinate every party in a NEXPEC-brokered war room, while the SLA Sentinel keeps report deadlines honest.
03
Audit-grade delivery
Photos, findings and signatures land in a cryptographically-sealed report, and vendor certificates are sealed the same way, fingerprinted and blockchain-anchored through our Trust Spine. Approve to release escrow.

Trust, engineered in

Three guarantees no other marketplace can make.

Every line of NEXPEC was built around a single question: would an auditor sign off on this in court? If the answer wasn't yes, we rebuilt it.

Stripe-backed escrow

Money is held until the job is signed.

Funds enter escrow at dispatch and release only when the report is approved. No deposits, no chasing invoices, no leverage games.

Cryptographic affidavits

Every report is Ed25519-signed.

On submission, the report's hash is signed by the inspector's key and the platform's witness key, then anchored to Bitcoin through our Trust Spine. Vendor certificates are sealed the same way. Verifiable in court, immutable forever.

Industrial Black Box

Every mutation is audit-grade.

A schema-level trigger captures who, when, why, and what, before-and-after diffs included. Discoverable, exportable, RLS-gated.

Provable AI Co-Inspector

An AI Co-Inspector that can't lie.

A signed model runs on the inspector's own device, flagging corrosion, cracks and weld defects in real time. Every finding is cryptographically bound to the exact model that produced it. No cloud, no edits, no doubt.

Cryptographic Seals

Sealed. Then anchored to Bitcoin.

Every accepted finding folds into a tamper-evident seal, a five-part cryptographic root signed by the inspector. We timestamp that seal into the Bitcoin blockchain, so a report's integrity is provable by anyone, forever. No trust required.

Offline-First Field Capture

Built for the field. Not the Wi-Fi.

Inspectors capture photos, findings and signatures with zero signal. Everything is sealed on-device and syncs the moment a connection returns, nothing lost, nothing duplicated, even days off-grid.

The platform, at a glance

One platform. Five disciplines. Audit-grade by design.

NEXPEC indexes the entire industrial inspection surface, from API 653 storage tank reads to PSM compliance audits, with structured scope templates, signed reports, and inspectors verified against named credentials.
