Sumary, an AI accounting software company founded in Copenhagen, has raised a $25M (about £19M) seed round led by Singular and is making London its commercial hub.
The round was announced on 10 November. Existing investors byFounders, Partech and Tenity invested again. Angels include Qonto co-founder Steve Anavi and Linear co-founder Tuomas Artman.
Sumary says it is the largest seed round ever raised by an accounting software company in Europe.
Who founded Sumary?
Sumary was founded by Pascar Sivam, Bastian Schneider, Lucas Rantzau, Frederik Hvilshøj and Frederik Skov Wacher.
Two of them, Sivam and Skov Wacher, are moving to London to lead the UK push. Denmark stays the base for technology and AI research.
What does Sumary's software do?
Sumary builds AI agents for accounting firms. The agents do the preparation work in bookkeeping and accounts, and accountants review the results.
The pitch is aimed at established practices. Many face new AI-native accounting firms that promise lower fees, and Sumary wants to give incumbents the same tools.
How fast has Sumary grown?
The seed comes less than a year after a $4.2M pre-seed in November 2025. Tenity, which co-invested in that round, said byFounders led it with Partech and founder angels.
That takes total funding to $29.2M. The new round is nearly six times the size of the pre-seed.
Jeremy Uzan, general partner at Singular, said Sumary has one of the strongest founding teams the firm has seen in Europe at this stage, with exceptional commercial momentum.
Where will Sumary expand?
The plan has three parts. Benelux is the first new market in mainland Europe, London becomes the sales and commercial centre, and Copenhagen keeps the engineering and research teams.
The company is hiring across commercial, product, engineering and research roles. Trade title International Accounting Bulletin reported the founders' move to London as part of a bigger UK focus.
Why London?
London puts Sumary close to a large base of UK accounting firms, the customers its founders are moving there to sell to.
Choosing London as a commercial base is a vote of confidence in the UK as the place to sell B2B software in Europe, even when the product is built elsewhere.
What this means for UK founders
Sumary is the latest overseas startup to set up its go-to-market team in London. It adds competition for UK accounting tech founders, but it also brings senior hires and capital into the London startup scene.
AI agents that take over whole workflows are drawing the biggest early rounds this year, from Tano in creator marketing to Sumary in accounting. You can follow the wider trend in Bizztor's UK AI startup funding data.
