Mynt, a Swedish fintech that sells corporate cards and spend-management software, said on September 10, 2026 that it had acquired 100 percent of CostPocket, an Estonian company that makes an AI-driven receipt-capture and expense-reporting tool. The announcement was issued from Stockholm, Tallinn and Helsinki.
The companies did not disclose the price or how it was paid.
CostPocket will keep operating as a separate company in Finland and the Baltic states, with its existing brand, product, management and team. Mynt said customers, employees and partners would see no changes, and that CostPocket would gain access to Mynt's corporate cards, payment infrastructure and spend-management platform.
What CostPocket built
CostPocket was founded in 2016. Its software turns paper and digital receipts into expense reports, using AI to read and sort the documents so that employees do not have to type in the details by hand. The product runs on mobile and on the web and is used by both employees who submit expenses and the accountants who process them.
The company's main asset is its reach into local bookkeeping. CostPocket connects to more than 40 accounting and ERP systems and has been localised for Finland and the three Baltic states. It sells to businesses, accountants and software partners, and has offices in Tallinn, Riga and Helsinki.
CostPocket did not publish a customer count or headcount with the announcement.
“Becoming part of Mynt gives us access to Mynt's proven and scaled payment infrastructure, while allowing CostPocket to remain CostPocket. We will continue operating as a separate company with the same product, brand, and team, focused on the customers and partners in our existing markets.”
Why Mynt is buying
The deal grew out of an earlier technology partnership. Under that arrangement CostPocket launched its own business card, issued on Mynt's infrastructure. Mynt described the full acquisition as the next step after that partnership.
For Mynt, the purchase adds a product that is already embedded in local accounting workflows in markets where it is still building a presence. Mynt sells directly in Sweden, Norway, Finland and Denmark, and the Baltic states are new territory for it. CostPocket, in turn, gains a larger parent with an established card and payments stack.
Baltsar Sahlin, Mynt's chief executive and co-founder, said the two companies shared a product mindset and the aim of removing manual financial administration, and that together they could strengthen CostPocket's offering and its position in the region.
Toni Kivinen, CostPocket's chief executive, said the deal gave the startup access to Mynt's payment infrastructure while allowing it to keep its own identity. He also described the sale as a milestone for the company's founders and early investors, saying it showed that a product built in the Baltics could find a place in the Nordic fintech market.
The buyer
Mynt was founded in 2018 and is based in Stockholm. It offers corporate cards together with software that automates receipt handling and syncs spending data with accounting systems. The company says it serves more than 30,000 businesses; in a 2025 announcement it said it had passed 20,000 customers and was expanding into Finland.
Mynt has raised venture funding to pay for that growth. In April 2023 it raised 100 million Swedish kronor (about $9.5 million) in a round led by Vor Capital, and in December 2024 it closed a €22 million (about $23 million) Series B, also led by Vor Capital. Visa has also announced an investment in Mynt alongside an expanded reseller partnership, without giving an amount. Mynt has also announced a partnership with Nordea to launch a business credit card for small and medium-sized companies across the Nordic countries.
What happens to customers
Mynt said CostPocket's customers would keep using the same product under the same brand, and that the startup's management would stay in place. The companies did not set out a timeline for combining products, though they said CostPocket would be able to offer Mynt's cards and spend-management tools to its users.
CostPocket's funding history is thinly documented. The press release refers to founders and early investors but does not name them or say how much the company had raised.
A consolidating market for spend management
The deal is the latest example of corporate-card companies buying expense and accounting tools to cover more of a customer's finance workflow. Customers of card providers increasingly expect receipt matching, approval flows and bookkeeping exports in the same product. Buying a locally integrated tool is a faster way to add those features in a new country than building connections to dozens of accounting systems from scratch.
For Mynt, the CostPocket purchase extends its reach from the four Nordic countries where it sells directly into the Baltic states, and adds a team that already knows the local accounting software those customers use.
