Reid Hoffman backs €18M round for ex-Qonto exec building AI alternative to accounting firms

Integral has closed an €18 million Series A, with Mosaic Ventures and Reid Hoffman leading the round. The Berlin startup says that puts its total funding above €30 million in less than two years. That is a fast run for a company that only launched in October 2024.

The pitch is blunt. Integral is not packaging tools for accountants and tax advisers. It is a licensed tax advisory firm, run as Integral Tax GmbH, that uses its own platform to do the work. AI agents handle invoice reconciliation, transaction posting, payroll, and tax filing. A qualified professional then checks the result and signs off.

That model seems to be resonating. The company says AI agents now handle full bookkeeping for more than half of its clients, and jobs that used to take weeks are down to a few hours. Lukas Zörner, who co-founded Penta and later ran Qonto’s German operations after its 2022 acquisition, is now focused on automating accounting for small businesses alongside Anil Can Baykal.

Integral is also drawing a line between itself and better-known rivals. Pennylane, the French accounting platform that recently raised $204 million at a $4.25 billion valuation, sells software to 6,000 accounting firms. Cortea, another Berlin player backed by Mosaic and Cherry Ventures, sells tools to auditors. Integral wants to be the auditor.

That ambition comes with a warning label. Bench Accounting tried something similar in the US, raised $113 million, and shut down in December 2024 after failing to scale. Integral’s edge is that it works inside Germany’s licensing system rather than outside it. The new money will go into better AI agents for bookkeeping, payroll, and tax, plus more commercial and engineering hires.
