Limetax raises €36M to build an AI-powered group of German tax firms

Limetax has raised €36 million – a €6 million pre-seed led by Motive Partners plus a €30 million credit facility from a consortium of German banks – to buy up German tax and accounting firms and run them on its own AI platform.

Germany runs on roughly 54,000 tax and accounting firms, per the announcement coverage, and for years the fintech playbook was to sell them software they were slow to adopt – yet the most ambitious tax-tech story of the week is a Berlin startup that would rather buy the firms than pitch them. Below, I unpack the round, the roll-up behind it, the market it is compounding into, and why a former finance minister writing an angel cheque is the detail that stays with me.

Six million in equity, thirty million in bank debt

Limetax announced the €36 million package on 9 September 2026. The equity half is a €6 million pre-seed led by Motive Partners, the New York fintech investor, joined by Activant and Heliad. The angel list reads like a map of German operator money: Christian Lindner, Germany’s former federal finance minister; Alexander Kudlich, co-founder of 468 Capital; and Moss founders Anton Rummel and Ante Spittler.

The other €30 million is not equity at all – it is a credit facility from a consortium of German banks, there to finance acquisitions. The structure tells you the strategy before the press release does: equity pays for the platform, debt pays for the firms.

The company says the money will accelerate its consolidation of the German tax and accounting market and expand its AI agent platform across the firms it acquires.

Four firms, seven offices, eight months

Limetax was founded in Berlin in January 2026 by Christoph Gamon, who co-founded Razor Group and served as its CFO after stints at Rocket Internet and UBS; Maximilian Meyer, a Razor Group founding team member who previously passed through Lazard and N26; and Christoph Dansard, a founding engineer at Augustus who studied at the Technical University of Munich.

Eight months later the group counts around 150 people across four acquired firms and seven locations, with annualised revenue already in the double-digit millions, per the company. The product is an agentic AI layer that plugs into DATEV – the software backbone used by more than 60,000 German tax professionals, per Tech Funding News – and automates bookkeeping, payroll and financial statements, with humans reviewing the output for legal accountability. In early deployments, the company says monthly bookkeeping per client dropped from around 20 hours to six.

“The future of accounting & tax advisory will not be built by adding another AI tool. It will be built by rethinking advisory and technology together from the ground up,” said Gamon in the announcement.

If the playbook sounds familiar, it should. Razor Group rolled up Amazon sellers; the same team is now rolling up Steuerberater. Different asset, same discipline: buy recurring revenue, standardise the operations, let software do the compounding.

A software market compounding at 12.3% a year

The segment Limetax automates is sizeable and growing at software pace: Grand View Research puts Germany’s tax management software market at $1.36 billion in 2025, heading for $3.38 billion by 2033, a 12.3% CAGR over 2026-2033. And the software is only the visible half – the services layer of tax advisory sitting on top of it is what Limetax is actually buying its way into, one firm at a time.

Europe has been funding the tool wave of this thesis for a while. Our own records show Integral raising €12 million for its AI accounting platform and Kabilio raising €4 million for AI accounting tools in Spain, both in November 2025. Those companies sell software to firms. Limetax just raised more than double the two combined, to own the firms themselves – at pre-seed. That is not a bigger version of the same bet; it is a different bet.

The finance minister writes an angel cheque

So why does a consortium of German banks lend €30 million to an eight-month-old company? Because the collateral is not a model or a roadmap – it is acquired firms with recurring, regulated revenue. That is the quiet advantage of the roll-up route to AI: the technology risk is wrapped in cash flow that bankers can actually underwrite.

The reality is less flattering on the equity side: the lead cheque for a Berlin pre-seed came from New York, with Motive Partners and Activant doing the leading while German institutional seed money watched. The good news is the operator bench showed up at home – Moss founders, a 468 co-founder, and Christian Lindner, who spent years running the ministry whose paperwork these 54,000 firms process. When the former finance minister backs the startup automating tax compliance, that is German pragmatism telling you where it thinks this is going.

What we are seeing, from Mistral’s sovereignty-scale Series D down to a Berlin pre-seed, is European AI money moving from tools to infrastructure – and in Limetax’s case, to ownership of the customer itself. Every round we track lands in our fundraising database, and the ownership wave is just starting to register there.

Watch whether the next Limetax acquisitions come faster and cheaper than the first four – that is the number that proves the model. The tool wave taught Germany’s advisers to try AI. The ownership wave intends to make the decision for them. The opportunity is clear.
