Sumary raises $25M seed: Europe's biggest for accounting

Lead

Sumary, a Copenhagen startup that builds AI software for accounting firms, announced a $25M seed round on November 10, 2026. Singular led the round, and existing backers byFounders, Partech and Tenity took part. The company describes it as the largest seed round for accounting software in Europe, a claim it made itself and one that is hard to verify independently.

The round arrives less than a year after a $4.2M pre-seed led by byFounders in November 2025. Total funding now stands at $29.2M. Sumary did not disclose a valuation.

What Does Sumary Actually Do?

Sumary sells an operating system for accounting firms, not for the companies those firms serve. Its software runs on top of clients' existing bookkeeping systems and handles the monthly close, VAT returns and year-end preparation. An accountant reviews and approves the output before it goes anywhere.

That positioning matters. Sumary is not replacing the ledger or the accounting package. It targets the preparation work that fills junior accountants' calendars, which is where firms say they are short of people.

The company reports that customers spend 50% less time on monthly close and 75% less on VAT returns after three months of use. Those figures come from Sumary itself, and the company has not published methodology or sample sizes.

Who Is Using It?

Named customers include Deloitte, Grant Thornton and Baker Tilly, alongside unnamed large UK firms. Sumary also says it works with most of the 20 largest accounting firms in the Nordics.

Big-firm logos at seed stage are an asset, but they say little about contract size. The company has not disclosed revenue, annual recurring revenue or headcount, so the scale of those relationships is unknown. Enterprise accounting buyers typically run lengthy pilots, and a logo can mean anything from a single team trial to a firm-wide rollout.

Who Founded It and Who Else Invested?

Pascar Sivam, a former McKinsey consultant, is CEO and co-founder. The founding team also includes Bastian Schneider, also ex-McKinsey, Lucas Rantzau, Frederik Hvilshøj and Frederik Skov Wacher, who serves as COO.

Angel investors include Steve Anavi of Qonto, Tuomas Artman of Linear, Stanislas Polu of Dust and Steffen Tjerrild of Synthesia. That is a roster weighted toward European software founders who have scaled products sold to professionals.

Sivam framed the problem in staffing terms: "Accounting firms are being asked to do more with fewer people." He added that the round lets Sumary bring its product to firms across the UK and Europe much faster.

Why Is a $25M Seed Possible Here?

Investors are paying up because AI accounting has become a funded category, and rounds in it are growing quickly. A $4.2M pre-seed followed by a $25M seed within roughly twelve months implies the early customer traction convinced backers to skip the usual intermediate step. Whether that traction translates into revenue is the open question, since none has been disclosed.

The competitive field is crowded. US-based Basis has raised $100M at a $1.15B valuation, and European and AI-native firms such as Skalar, Integral, Dougs and Gradient are working the same problem from different angles. Sumary's differentiator is its focus on large accounting firms rather than small businesses or in-house finance teams.

The risk is the usual one for a large seed: a high bar for the next round. Having raised $25M on traction at this stage, Sumary will need to show enterprise contracts expanding into recurring revenue to justify a Series A priced above this one.

What Comes Next?

Sumary plans to use the money to expand across Europe, beginning with Benelux. London becomes the commercial hub, and Sivam and Skov Wacher are relocating there. Denmark remains the base for technology development and AI research.

The move mirrors where the large firm customers sit. The UK has a deep concentration of big accounting networks, and winning there would give Sumary reference customers for continental sales. Hiring plans and a timeline for new markets were not disclosed.

Outlook

Sumary has turned a $4.2M pre-seed into a $25M seed in under a year on the strength of big-name customers and efficiency claims it has yet to back with public revenue figures. The next twelve months will test whether Deloitte-class logos become large, repeat contracts, and whether a Copenhagen-built product can win in a London market where well-funded rivals are already selling. A Series A will hinge on those numbers.
