Nexus Frontier Tech's ProvChain Ends AI's 'Verification Tax'

New technology proves every AI-generated result against its source, so professionals check only the exceptions and can sign the output, at up to 10x lower cost

LONDON, Oct. 14, 2026 /PRNewswire/ -- Nexus Frontier Tech today introduced ProvChain, the verification engine at the heart of its OneNexus platform. ProvChain tackles the biggest hidden cost of enterprise AI: the human time spent checking its work.

95% right, but which 95%?

AI was meant to transform office productivity. Yet in a poll of nearly 6,000 senior executives, about 90% said it had no impact on productivity, even though 69% of their firms use it, The New York Times reported on October 10.

The culprit is the "verification tax." A Workday survey found workers spend roughly 37% of the time AI saves correcting its output. As MIT Sloan's Christian Catalini told the Times: "The only A.I. that's useful is the A.I. that is verified."

The root problem is simple. Today's AI can say it is 95% right, but not which 95%. So professionals must recheck every figure, and the savings disappear.

Check 5%, Sign 100%

ProvChain tells you exactly where AI got it wrong. It pins every AI result to its exact source, has independent AI recheck it, and sends only the exceptions to Nexus experts with 20+ years at tier-1 banks, who correct and sign them. Because it rechecks only what it needs, ProvChain uses up to 10x fewer AI tokens, and it runs in the client's own private cloud.

That opens up the biggest prize: relying on AI for work that was previously too risky to touch, because professionals must put their name to every number. ProvChain is already in production in regulated processes:

• Credit spreading and lending decisions: analysts review a handful of flagged figures instead of rechecking entire financial statements, speeding the path to credit approval.
• Wealth statement verification: Val checks every client statement instead of a 2–3% manual sample that takes weeks, catching errors before they reach clients and giving broker-dealers, wealth managers and custodians a full audit trail.

"The industry has been selling AI that is mostly right. In finance, mostly right is worthless when your name needs to be on each result," said Danny Goh, Founder and CEO of Nexus Frontier Tech. "ProvChain proves each and every result and puts a named expert behind the exceptions. We sign so you can sign."
