Sumary says its $25 million seed is Europe's largest for accounting software

Sumary, a startup founded in Copenhagen that builds AI software for accounting firms, has raised a $25 million seed round. The Next Web reported the round on November 10. Singular led it, with existing investors byFounders, Partech and Tenity taking part. Angel investors include Steve Anavi of Qonto, Tuomas Artman of Linear and Steffen Tjerrild of Synthesia.

The size is unusual for a seed round. Sumary calls it the largest seed round for an accounting software company in Europe, a claim that comes from the company. Its previous round was a $4.2 million pre-seed in November 2025, led by byFounders.

The product does not try to replace the accountant. It handles the monthly close, VAT returns and year end preparation, working on top of each client's existing bookkeeping system. An accountant reviews and signs off each step. Sumary says firms that use it for three months spend 50 percent less time on a monthly close and 75 percent less on a VAT return. Those numbers are company reported.

The company reports traction among large accounting firms. Sumary says it works with most of the 20 largest accounting firms in the Nordics, naming Deloitte, Grant Thornton and Baker Tilly, and has signed large UK firms it did not name. Two co-founders, CEO Pascar Sivam and COO Frederik Skov Wacher, are moving to London, which becomes the company's commercial hub, and Sumary plans to expand into Benelux.

"Accounting firms are being asked to do more with fewer people," Sivam said. For makers, the concrete product choice is to work inside an existing professional workflow, while leaving the accountant responsible for reviewing and signing off the result.
