A Berlin startup that wants to rewire Germany's traditional tax advisory firms from the inside out has raised €36 million just eight months into its existence, betting that artificial intelligence can solve what founder Christoph Gamon calls the profession's fundamental constraint: not demand, but human capacity.
Limetax announced Tuesday it secured €6 million in equity led by Motive Partners, plus a €30 million credit facility from a consortium of German banks it declined to name. The capital will fund acquisitions of small accounting practices across Germany and the rollout of ATLAS, Limetax's proprietary AI platform designed to automate the grunt work of monthly bookkeeping, payroll, and financial reporting.
The company's pitch is straightforward, if audacious. Take equity stakes in conventional tax firms. Layer in software that does what junior accountants typically do. Keep the humans for judgment calls and client relationships. According to the company, early tests have compressed monthly bookkeeping from roughly 20 hours of work down to six.
Whether that efficiency survives contact with Germany's famously meticulous regulatory apparatus remains an open question.
Gamon, who co-founded and served as CFO at Razor Group before it scaled past half a billion dollars in revenue, insists Limetax isn't selling software. "We are not building another AI tool for firms," he said. Instead, the startup is buying firms outright and refitting them around technology that sits atop DATEV, the nearly ubiquitous software backbone used by some 54,000 German tax advisors.
ATLAS orchestrates what Limetax describes as "agentic AI" — autonomous software agents that book transactions, run payroll, and draft financial statements while human accountants review the output and affix their professional signatures. The platform supposedly keeps client data segregated and preserves Germany's strict professional secrecy requirements, though the company offered few technical details on how that segregation works in practice.
Limetax now operates four tax practices spread across seven German cities, employing around 150 people and generating what it characterizes as double-digit millions in euros of annualized revenue. The portfolio includes bplus in Berlin, Welzenbach Steuerberatungsgesellschaft in Lohr am Main and Würzburg, and Alltreu in Ludwigshafen. A fourth firm is listed as forthcoming.
Co-founder Maximilian Meyer, who also came out of Razor Group's founding team and previously worked at Lazard and N26, runs operations. CTO Christoph Dansard was a founding engineer at Augustus, the startup formerly known as Ivy. The broader team pulls from Taxfix, McKinsey, EY, Raisin, and KPMG, according to materials shared with investors.
The equity round drew participation from Activant Capital and Heliad, alongside a notable roster of angel investors. Christian Lindner, Germany's former finance minister, joined the round and wrote on LinkedIn that Limetax was among his first angel bets after launching an investment vehicle. Alexander Kudlich, co-founder of 468 Capital and a Rocket Internet veteran, also invested, as did Moss founders Anton Rummel and Ante Spittler.
"In tax advisory, demand isn't the bottleneck — available capacity is," said Michael Hock, a partner at Motive Partners, in the company's statement.
That capacity crunch is real enough. But Limetax is hardly operating in a vacuum. DATEV itself released an AI assistant called DATEV Copilot several months back, and the cooperative reported in June that north of 100,000 German bookkeeping engagements were already using its automation service for bank transactions. Roger Gothmann, co-founder of tax software firm Taxdoo, wrote bluntly on LinkedIn that "AI + DATEV is no longer a secret moat but a commodity."
Then there's Pennylane, the French accounting platform that announced a €175 million funding round in January and claimed a valuation around €3.5 billion. At the time, Pennylane said it served more than 800,000 companies and between 6,000 and 6,500 tax firms. The company has been expanding aggressively across Europe, Germany included.
Limetax is making a different wager than pure software plays, though. By taking equity in the firms themselves, it's absorbing the messy realities of running an accounting practice: hiring, client retention, regulatory compliance. The upside, in theory, is control. The downside is that rolling up fragmented service businesses is notoriously difficult, and layering in unproven AI adds another variable.
Uwe Tille of bplus, one of Limetax's partner firms, said in the announcement that the profession faces its biggest transformation ever. That may be true. Whether venture capital and bank credit can midwife that transformation faster than incumbents adapt is the real question Limetax will have to answer, probably sooner than eight months from now.
