Integral Raises €18M for AI Accounting & Tax Services

Berlin-based fintech innovator, Integral, has successfully closed an €18 million Series A funding round, signaling a significant advancement in the application of artificial intelligence within professional accounting and tax services. The substantial capital infusion was co-led by prominent venture capital firms Mosaic Ventures and Reid Hoffman, with crucial participation from existing backers Cherry Ventures, General Catalyst, and Puzzle Ventures. This latest funding brings Integral's total investment to over €30 million, underscoring strong investor confidence in its AI-native approach.

Founded in 2024 by Lukas Zörner and Anil Can Baykal, Integral is redefining how small and medium-sized businesses (SMEs) access essential financial services. Instead of developing software for accounting professionals, the company has built an integrated model that combines sophisticated AI agents with licensed human experts. This hybrid approach aims to deliver accounting, tax, and payroll services directly to businesses, tackling inefficiencies and labor shortages prevalent in the German market.

The core of Integral's offering lies in its proprietary AI agents, which handle the bulk of repetitive tasks within bookkeeping, tax preparation, and payroll processing. These agents manage everything from invoice reconciliation and bank transaction matching to account posting and the generation of tax filings. Critically, these automated processes are overseen and finalized by licensed professionals from Integral Tax, an affiliated German audit and tax firm, ensuring accuracy and compliance within a regulated environment.

This innovative model has already demonstrated tangible results. Integral reports that its AI agents now manage end-to-end bookkeeping for over half of its client base, drastically reducing turnaround times from weeks to mere hours. Furthermore, the efficiency gains have empowered professionals at Integral Tax to manage twice the number of clients compared to the beginning of the year. Feedback loops from these professional reviews continuously refine the AI's automation capabilities, creating a virtuous cycle of improvement.

“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,” stated Lukas Zörner, co-founder and CEO of Integral. “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.” This strategic focus addresses the critical need for scalable and reliable financial services in a sector facing demographic challenges.

The €18 million Series A capital will be strategically deployed to accelerate Integral's growth. Key areas of investment include expanding its AI engineering talent pool, recruiting more licensed accounting and tax professionals, and bolstering its commercial teams. The company also plans to further enhance its automation across all financial workflows and advance its proprietary compliance technology, solidifying its position as a leader in AI-driven financial services for SMEs. The fintech sector, particularly areas focused on automation and efficiency for professional services, continues to attract significant investment, with companies like Integral demonstrating the potential for AI to reshape traditional industries.
