$25m · Seed · Fintech · Copenhagen, Denmark
Copenhagen-based Sumary, which builds AI software for accounting firms and finance teams, has raised a $25m Seed round led by Singular. Existing investors byFounders, Partech and Tenity also participated, alongside angel investors including Steve Anavi, Tuomas Artman, Stanislas Polu, Steffen Tjerrild, Jannick Malling and Ben Freeman. Tech.eu reports that the capital will support expansion across Europe, beginning with Benelux, while London becomes the commercial hub and Copenhagen remains the centre of technology development and AI research.
The round follows a $4.2m pre-seed announced in 2025. The two financings are separate: $25m is the new Seed amount.
Accounting AI is becoming a distribution contest
Sumary sits on top of customers' existing ledgers, including Business Central, Xero, NetSuite and QuickBooks, rather than requiring an immediate system migration. Its software prepares month-end close, VAT and year-end work, checks transactions and produces reports for accountants to review. The company says approved changes are written back to the ledger as drafts and every action is logged, keeping the professional responsible for the final sign-off.
That design makes distribution through accounting firms central to the business. One firm can deploy the product across many client books, while Sumary can reuse integrations and workflow patterns without selling separately to every small business. The constraint is trust: accountants remain accountable for returns and financial statements, so automation has to be reviewable and fit the ledgers, controls and local tax work already in use. Tenity's investment note says Sumary now works with most of the Nordics' 20 largest accounting firms and names Deloitte, Grant Thornton and Baker Tilly among its customers.
European expansion raises the localisation test
Sumary's next step is not just adding sales coverage. Moving from the Nordics and UK into Benelux means supporting different chart-of-account conventions, tax workflows and firm practices while preserving a consistent approval trail. The company says its Copenhagen research team tests models against real accounting tasks before they reach client workflows. The commercial question for the Seed round is whether that validation and implementation process can scale across markets without turning each deployment into a bespoke project.
