Integral's $19M Raise: AI-Powered Accounting for SMEs

Jan de Vries · 2026-09-16

### Integral's $19 Million Bet on AI-Run Accounting Integral, a Berlin-based startup that uses AI to handle accounting, tax, and payroll for small and medium-sized businesses, just raised €18 million in Series A funding. That's about $19 million. Not bad for a company that's less than two years old. In total, they've raised over $32 million since 2024. The round was co-led by Mosaic Ventures and Reid Hoffman, with existing investors Cherry Ventures, General Catalyst, and Puzzle Ventures also chipping in. This follows a €6.3 million raise in February 2025 and the acquisition of cleverlohn, a German digital payroll provider, in November 2025. ### Why Investors Are Paying Attention Chandar Lal, Partner at Mosaic Ventures, put it simply: "With AI, it's possible to rebuild industries from the ground up – not just sell better software. In accounting, tax and payroll, the need is obvious as labour shortages are only getting worse. Integral is uniquely well positioned to solve that problem in Germany and beyond." He's got a point. Accounting and tax firms are struggling to find qualified staff. And for small businesses, compliance paperwork is a massive time sink. Integral's approach? Let AI agents do the heavy lifting while licensed professionals oversee and sign off. ### How It Works Founded in 2024 by Lukas Zörner and Anil Can Baykal, Integral combines licensed tax professionals with AI engineers. The company's AI agents reconcile invoices and bank transactions, create account postings, and prepare payroll runs and tax filings. For more than half of their clients, agents now prepare the books end-to-end, cutting the average monthly accounting turnaround from weeks to hours. Every review by a licensed professional feeds back into the platform, so the automation gets smarter with each client. And licensed experts remain in full control, reviewing and signing every filing. Zörner, co-founder and CEO, explained: "Software doesn't file your business's taxes. It doesn't run your payroll and it doesn't sign your annual accounts. A licensed professional does, and there are fewer of them every year. So instead of building yet another tool for professionals, we built the firm itself: AI agents do the work, licensed experts stand behind every result. The deeper our automation goes, the better the service." ### What Sets Integral Apart Integral Tax, an independent licensed firm affiliated with Integral, runs entirely on the platform. Since the beginning of the year, the firm's professionals have doubled the number of clients each can serve. That's a big deal in an industry where capacity is limited by human hours. The company is a recognised public audit firm (Wirtschaftsprüfungsgesellschaft, WPG) under the German Public Accountant Act (WPO) and is overseen by the Chamber of Public Accountants (Wirtschaftsprüferkammer). They also emphasize GDPR compliance: client data is stored and processed exclusively in European data centers, with strict access controls and confidentiality. ### The Bigger Picture As Reid Hoffman, who co-led the round, said: "AI's real promise is amplifying what people can do, not replacing them. Integral shows what that looks like in one of the most regulated, trust-dependent industries there is: agents that multiply the reach of licensed professionals, so every small business gets the kind of financial expertise once reserved for large corporations." That's the pattern the next decade of professional services will follow. And Integral is building it where the bar is highest: in Germany, a country known for its rigorous accounting standards. With this fresh capital, Integral plans to push automation even deeper across all workflows. If they succeed, they might just change how small businesses handle their finances forever.
