Sumary Raises $25 Million Seed Round for AI Accounting Platform

Sumary, a Copenhagen-based AI accounting platform, raised a $25 million seed round led by the venture firm Singular, the company announced on November 10, 2026. The Sumary funding comes less than a year after a $4.2 million pre-seed round.

The money will move the company’s commercial base to London and carry it into continental Europe, starting with the Benelux countries. Denmark remains the centre for technology and AI research.

For accounting firms, the round matters because it funds a product built for practices rather than for small businesses directly. Sumary automates monthly closes, VAT returns and year-end preparation, and it runs on top of the ledgers clients already use. Firms in the UK and the EU are the next customers it is courting.

A $25 million seed is large for the category. The pre-seed round, led by byFounders with Partech, was $4.2 million, so total Sumary funding now stands at about $29.2 million.

Sumary funding: who put in the $25 million

Singular led the round. Existing investors byFounders, Partech and Tenity took part again.

Six founders of other technology companies invested as angels: Steve Anavi of Qonto, Tuomas Artman of Linear, Stanislas Polu of Dust, Steffen Tjerrild of Synthesia, Jannick Malling of Public.com and Ben Freeman of Omnea.

Sumary did not disclose a valuation. Jeremy Uzan, general partner at Singular, said: “Sumary has one of the strongest founding teams we have seen in Europe at this stage.”

The pre-seed backers had set out their own case a year earlier. byFounders pointed to the EU’s VAT in the Digital Age rules, which will make digital invoicing and reporting mandatory by 2030, and to AI that can now handle most bookkeeping work and adapt to local tax rules. It put the market at almost €100 billion a year in accounting spend across Europe’s 25 million small and medium businesses.

What Sumary does for accounting firms

Sumary describes itself as an AI operating system for accounting. It prepares month-end, VAT and year-end work for sign-off, answers questions about a client’s profit and loss, balance sheet and cash flow with figures traced to source, and flags VAT, coding and pricing errors.

It also produces management packs and consolidates groups across entities and currencies.

The platform connects to Business Central, Xero, NetSuite and QuickBooks rather than replacing them. Approved changes are written back to the ledger as drafts, and nothing is posted until someone at the firm approves it. That keeps the accountant’s sign-off at the centre of the process, which matters for firms whose partners put their names to the work.

The product is live. Sumary said firms using it cut monthly close time by 50% and VAT return time by 75% after three months.

A research team in Copenhagen tests AI models on real accounting tasks before any of them touches a client account, assessing the data they use, the controls around them and the checks on their output. For firms comparing tools, the month end close software guide shows where this kind of workflow automation sits against established close platforms.

Pascar Sivam, Sumary’s co-founder and chief executive, said: “Accounting firms are being asked to do more with fewer people.” He added: “That is what we have built. This round lets us bring that to firms across the UK and Europe much faster.”

Customers behind the Sumary funding round

Sumary works with most of the 20 largest accounting firms in the Nordics and has signed UK firms. Its named customers include Deloitte, Grant Thornton, Baker Tilly, Accru Partners, Oury Clark, RPGCC, Zignifikant and Baltic Assist.

A Deloitte partner is quoted on the company’s website as saying: “Sumary’s AI and accounting workflows are a superpower every accountant deserves.”

The company has not published a customer count or revenue. It sells through accountants, who act as the channel to their own small business clients, a model that gives it large firms and small practices at the same time.

The UK is the first target for the Sumary funding. Sivam and co-founder Frederik Skov Wacher, the chief operating officer, are relocating to London to lead growth there.

The team Singular and byFounders backed

Sivam is a former McKinsey consultant and a repeat founder. byFounders says he grew revenue past €50 million at his previous company, Blazar.

Lucas Rantzau, the chief product and technology officer, sold an earlier startup, Stori, and built Sumary’s first AI prototype in about two and a half months. Frederik Hvilshøj, chief scientist, was previously a lead machine learning engineer at Encord.

Bastian Schneider, the chief bookkeeper, is a former McKinsey consultant who was previously chief financial officer at the Danish food company Grød. He leads onboarding and customer success.

That mix of operators and engineers is what early investors cited. Casper Bjarnason of byFounders said at the pre-seed stage that the founders were “exactly the kind of founders who can build one of the category-defining companies in Europe”.

How Sumary funding compares with its rivals

The competitive field is crowded and better capitalised. Basis raised $100 million in a Series B and reached a $1.15 billion valuation, selling autonomous agents to large US firms. Pennylane raised $200 million to expand a French accounting platform that firms use as their ledger.

US-based Digits and Rillet build AI-native ledgers and ERP systems for companies. Sumary does the opposite. It keeps the client’s existing ledger and puts the firm’s workflow on top.

That positioning lowers the cost of adoption for a practice with hundreds of clients on Xero, QuickBooks or Business Central, since nobody has to migrate. It also leaves Sumary dependent on the ledger vendors’ integrations.

Other European startups are chasing the same firms. Kabilio raised €10 million in a round led by Picus Capital and Visionaries, and Maxima raised $41 million for enterprise accounting.

Sivam said: “Dozens, and probably soon hundreds, of AI accounting firms are being built as we speak.” On the evidence of the funding rounds so far, he is not exaggerating the field.

What comes next for Sumary

The European accounting industry generates an estimated €133 billion in annual fees, with much of the work still manual. Staff shortages and pressure to grow client capacity without adding headcount are what drive firms to buy.

The next test is the UK. Sumary has signed firms there but has not named a launch date for the Benelux countries, so the first Benelux customer announcement is the milestone to watch after the move to London.
