Plinto Raises €2.9M to Catch Duplicate Invoices Before They Bite

Your daily brief on leadership and business

Every finance team has a story about the invoice that got paid twice. Copenhagen startup Plinto wants to make such stories rarer. Founded in early 2025 by Jakob Nielsen, CEO Nermina Suljevic and Sebastian Rehnby, the company has raised €2.9 million from People Ventures and Emblem.

Spot checks are not enough

At larger companies, transaction volumes are so high that finance teams usually rely on spot checks or month-end reviews. That leaves room for incorrect charges and duplicate invoices to slip through until the money has already gone. Plinto builds AI agents that take over checks normally done by hand, comparing transactions with contracts, budgets and internal policies.

The agents connect to ERP software, documents, banking systems, Slack and Microsoft Teams. When something does not match, they investigate, gather evidence and can follow up with suppliers, request credit notes or prepare corrections for a person to approve. “We're building AI agents that find deviations, investigate them and take action, so errors get fixed,” Nielsen said.

Small errors, thin margins

Plinto already has paying customers and pilot projects in logistics, real estate, facility services and food production. In one area of a single customer's business, the agents flagged about 430 discrepancies a month. In another case, they caught a duplicate invoice submitted under a different supplier name before the second payment went out, the kind of creativity finance teams could happily live without.

“Many of our customers work with low margins, so even small errors can quickly add up,” Suljevic said. The startup will use the money to speed up product development, win more enterprise customers and begin expanding beyond Denmark.
