PayeeGuard
Verify who gets paid before an AI agent sends the money
● The Problem
Finance teams are handing payment initiation to agents that read invoices and queue transfers. Bank details are the easiest field on an invoice to change, and an agent has no instinct that a familiar supplier suddenly wants a new account. Basware bought the payment fraud vendor Trustpair in August 2026 to put verification in front of exactly this.
● The Solution
A verification call any agent or AP workflow makes before a payment is released. It checks the payee account against bank records and prior payment history, flags account changes on known suppliers, and returns allow, hold, or block with a reason an auditor can read.

Market Timing
Basware acquired Trustpair in the week of 25 August 2026, and Socure raised $156 million at a $5.2 billion valuation while folding in the agentic AI startup Fravity. Two deals in one week aimed at verifying who sits on the other end of an automated transaction.

Suggested Tech Stack
Go-to-Market Strategy
Sell to AP automation and agent platform vendors first, since one integration protects thousands of downstream companies. Price per verification. Publish loss data on supplier bank detail fraud, which finance leaders already fear and cannot currently quantify.
Target Audience
Monetization
Usage-BasedCompetitive Landscape
Trustpair sells to large enterprises and now belongs to Basware. Nsknox and Cybersource Payer Authentication chase the same buyer at the same price point. None ship an agent-callable interface, so a team wiring an AP agent this quarter has nothing to call before it pays.
Why Now?
Agents moved from drafting payments to releasing them during 2026, and the controls were built for humans who notice when a supplier changes banks. Acquirers priced the gap in August 2026, which is the clearest signal that the buyers exist.
