Sumary raises £19m led by Singular and Partech
This article covers Sumary, a fintech startup, raising £19m in a growth funding round to accelerate its European expansion, establish London as its commercial hub and scale its Copenhagen AI research team. The funding aims to drive go-to-market growth across the UK, Benelux and wider Europe and to support accountancy practices by automating core accounting workflows.
Sumary, a fintech startup, has raised £19 million in a growth funding round to accelerate its European expansion, establish London as its commercial hub and scale its Copenhagen-based AI research team. The money will fund go-to-market growth across the UK, Benelux and wider Europe and support the company’s claim to automate core accounting workflows for firms and their clients.
Why it matters
Accountancy practices across Europe face rising demand and staffing pressure. Tools that truly handle preparation work — not just bookkeeping interfaces — can shift accountants’ time back to client advisory and oversight. Sumary’s £19 million raise is notable because it follows a £3 million pre-seed less than a year ago, showing quick investor appetite for automation in accounting and the fintech adjacent space.
The company already counts several of the region’s largest firms among customers, including Deloitte, Grant Thornton and Baker Tilly, and says it works with the majority of the Nordics’ 20 largest accounting firms. Early user figures from the company suggest measurable efficiency gains: firms report spending 50% less time on a monthly close and 75% less on VAT returns after three months on the platform.
Inside the product
Sumary describes itself as an AI operating system for accounting work. Its software orchestrates core accounting workflows — from monthly closes to VAT returns and year-end preparation — across every client and the ledger that client already uses. Each processing step is presented for an accountant to review and sign off rather than to be rekeyed or manually reconciled.
A research team in Copenhagen has built a benchmark of real accounting tasks that Sumary uses to test new models. The benchmark assesses the financial context provided to a model, the controls it must meet and the checks on its output. Sumary says every leading model is measured against this benchmark before it is trusted with client books, reflecting the importance of auditability and control in financially regulated workflows.
Founders have positioned Denmark as the centre of technology and AI research while moving commercial leadership to London to drive sales and partnerships in the UK market. The product is already in contracts with major accounting firms, which lends early credibility but also raises questions about integration, long-term auditability and regulatory acceptance as AI handles more preparatory work.
Who are the investors?
The round is led by Singular. Existing backers byFounders, Partech and Tenity participated alongside angel investors including Steve Anavi (Qonto) and Tuomas Artman (Linear). The new funding follows a £3 million pre-seed round Sumary closed less than a year earlier.
In the announcement, Jeremy Uzan, General Partner at Singular, said:
Sumary has one of the strongest founding teams we have seen in Europe at this stage and their commercial momentum is exceptional. They have combined deep AI research capabilities with an understanding of how accounting firms operate and are already winning the trust of some of the industry's largest players. We believe Sumary has what it takes to become the defining AI platform for accounting in Europe.
In the announcement, Mads Fauerskov, Partner at Deloitte, said:
Sumary's AI and accounting workflows are a superpower every accountant deserves.

Founder perspective
The company was founded by former McKinsey consultants Pascar Sivam (CEO) and Bastian Schneider (Chief Bookkeeper), with Lucas Rantzau (CPTO), Frederik Hvilshøj (Chief Scientist, formerly Lead ML Engineer at Encord) and Frederik Wacher (COO).
In the announcement, Pascar Sivam, Co-founder & CEO at Sumary, said:
Accounting firms are being asked to do more with fewer people. Software has to take on the preparation properly, so accountants can give their time to the people who depend on them: their clients and their own teams. That is what we have built. This round lets us bring that to firms across the UK and Europe much faster.
Sivam and Wacher are relocating from Copenhagen to London to lead UK growth while R&D remains in Denmark. The team’s cross-border split reflects a common playbook for European startups: keep research close to talent pools and scale commercial operations from London.
The bigger picture
Sumary’s raise sits at the intersection of two trends in the UK and European markets: rapid adoption of AI tools in core business functions, and continued investor interest in fintech-adjacent solutions that can be embedded into professional services. For accounting firms, the attraction is clear if the efficiency claims hold up under independent validation and regulator scrutiny.
The deal also underscores London’s pull as a commercial hub for fintech startups expanding across Europe, even when product engineering remains in other Nordic centres. If Sumary can translate its early contracts with large firms into repeatable deployments — and maintain strong controls around model outputs — it could become a reference point for vendors aiming to automate regulated financial workflows.
The outcome will be watched by fintech investors and accounting firms across the UK and Europe as a test of how far AI can be entrusted with core preparatory work in finance.
