Plinto has raised €2.9M in a pre-seed round, the earliest stage of outside funding, to build software agents that check a company’s invoices, orders and payments against its contracts and rules. The Copenhagen, Denmark, startup said on its blog that People Ventures, a Nordic early-stage fund, and Emblem, a European venture firm, led the round.
A group of business angels also invested, though none of them has been named. Plinto says the money will speed up product development and take it into new markets, beginning with its first move outside Denmark. It also wants to sign up more large companies as customers.
Jakob Nielsen, one of Plinto’s three co-founders, says businesses already record every transaction in their systems, yet checking that those transactions match agreements and rules is still mostly done by hand.
“We’re building AI agents that find deviations, investigate them and take action, so errors get fixed,” he said.
Agents That Check Transactions
Plinto’s website calls the work controlling, the job of making sure that what a business books and pays matches what it agreed to. Its agents sit on top of a company’s enterprise resource planning (ERP) system, the software that runs its accounts, and connect it to documents, bank accounts and chat tools such as Slack and Microsoft Teams.
The site walks through a supplier invoice as an example. An agent compares the prices with the agreed supplier terms and asks the buyer to confirm the goods arrived before the bill is posted. It then checks which accounts the invoice was booked to, schedules the payment and confirms the bank transfer once it goes through. In Vienna, the startup reebuild runs similar checks for builders, matching construction invoices against what was ordered and delivered.
When something does not match, the company says, an agent can write to the supplier, request a credit note cancelling all or part of the bill, or draft a fix for staff to sign off. Plinto keeps the ERP in place and says it connects to systems including Microsoft Business Central, e-conomic, Fortnox, Xero and Visma, plus more than 2,700 banks.
Plinto says it keeps customer data inside the European Union and does not feed it into AI model training. It is also working towards certification under ISO 27001, the international standard for information security.
Early Customers And Results
Plinto says it already has paying customers and pilot projects in logistics, real estate, facility services and food production, though it has not named any of them. One customer found about 430 mismatches a month in a single part of its business, the company says.
Another customer received the same invoice twice, the second time under a slightly different supplier name. Plinto says its agents spotted the copy within a minute of it arriving, before it could be paid a second time.
Nermina Suljevic, Plinto’s co-founder and chief executive, said even small mistakes hurt customers whose margins are already thin.
“The problem is that they’re often only discovered after the money has been paid,” she said. “We want companies to catch and fix errors before they hit the bottom line.”
A Founding Team From Peakon
Suljevic, Nielsen and their fellow co-founder Sebastian Rehnby all worked at Peakon, the Danish employee feedback company that Workday agreed to buy for about $700M in cash in 2021. Andreas Garnæs, Plinto’s chief technology officer, is also a former Peakon employee.
Guillaume Durao, Emblem’s founder and general partner, called Peakon “my first investment in Denmark” and noted that each of Plinto’s founders had helped build it. “I’m very happy to back them again on this new journey,” he said. Emblem has offices in Paris, Copenhagen, Stockholm and London, and its portfolio includes the app-building startup Lovable.
Magnus Stagsted, a partner at People Ventures, named the team as his first reason for investing. His second was personal: “I’ve tried to fix this problem myself,” he said. The Copenhagen fund works with founders on finance, sales and getting to market, and its portfolio includes the legal research startup Pandektes.
The founders began building Plinto in early 2025, using a company registered in 2022 as Propsponge ApS that took its current name in June 2025, Danish company records show. The same records list Durao on the board, which Nielsen chairs.
Plinto now has new money from a round led by a Nordic early-stage fund and an investor who backed its founders’ last company. It plans to use it to build out its agents, sign up larger customers and make its first move beyond Denmark.
The idea behind it is simple: most companies already record every invoice and payment, but checking them against contracts and rules is still largely done by hand. Plinto’s results so far come from its own customers, none of them named, so the next test is whether those gains hold as it grows.
