Berlin-based accounting technology company Integral has raised €18 million in Series A funding. The company will use the investment to expand its AI-powered accounting, tax and payroll services for small and medium-sized businesses.
The funding round was co-led by Mosaic Ventures and Reid Hoffman. Existing investors Cherry Ventures, General Catalyst and Puzzle Ventures also participated in the round.
With this latest investment, Integral has now raised more than €30 million in total funding. The new capital will support the company’s continued growth and development of its AI-powered financial services.
Integral will use the Series A funding to hire more people for its AI engineering, professional accounting and commercial teams.
The company also plans to automate more accounting, tax and payroll tasks and improve its own compliance technology for regulated financial work.
“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, ” said Lukas Zörner, co-founder and CEO of Integral.
Founded in 2024 by Lukas Zörner and Anil Can Baykal, Integral is building an AI-based accounting service for professional accounting work, starting in Germany. Instead of simply selling software to accountants and tax professionals, Integral combines AI agents with licensed professionals to provide accounting, tax and payroll services directly to SMEs.
Integral Tax, an independent German audit and tax firm linked to Integral, operates through the company’s platform. Its AI agents handle routine tasks such as bookkeeping, tax and payroll work.
The AI agents can reconcile invoices and bank transactions, create accounting entries, and prepare payroll and tax filings. Licensed professionals then review the work and approve the final results.
Integral says its AI agents now handle the full bookkeeping process for more than half of its clients, reducing the average monthly accounting turnaround from weeks to just hours. The company also says professionals at Integral Tax have doubled the number of clients they can serve since the start of the year. Feedback from licensed professionals is used to further improve the platform’s automation.
