Integral Raises €18M for AI-Driven SME Finance Services

Berlin-based Integral has successfully closed an €18 million Series A funding round, signaling a significant advancement in its mission to revolutionize accounting, tax, and payroll services for small and medium-sized enterprises (SMEs) through artificial intelligence. This latest infusion of capital, co-led by prominent investors Mosaic Ventures and Reid Hoffman, with continued support from existing backers Cherry Ventures, General Catalyst, and Puzzle Ventures, will fuel the company's expansion and deepen its AI automation capabilities.

Founded in 2024 by Lukas Zörner and Anil Can Baykal, Integral differentiates itself by integrating licensed tax professionals with advanced AI engineers. This unique synergy allows the company to offer AI-powered financial operations that handle complex tasks such as invoice reconciliation, bank transaction matching, account posting, payroll processing, and tax filings. The core innovation lies in AI agents performing the bulk of the work traditionally requiring extensive human resources, thereby freeing up founders to concentrate on business growth rather than administrative burdens.

The impact of Integral's approach is already evident. The company reports that for over half of its clients, AI agents now manage the entire bookkeeping process end-to-end. This has dramatically reduced the typical monthly accounting turnaround time from weeks to mere hours. Crucially, licensed professionals maintain oversight, reviewing and approving all filings, ensuring compliance and accuracy. This model addresses the growing labor shortage in the accounting and tax sectors, a challenge particularly acute in markets like Germany.

Lukas Zörner, co-founder and CEO, emphasized the transformative potential of their AI-native service model. "Software alone doesn't file taxes or sign annual accounts; licensed professionals do, and their numbers are dwindling. Instead of creating another tool, we've built the firm itself, powered by AI agents overseen by expert humans," Zörner stated. "This investment allows us to push automation further across all workflows and validates our vision for rebuilding the industry with AI-native services." Integral's affiliated licensed firm, Integral Tax, operates entirely on this platform, serving businesses nationwide and demonstrating the scalability of their model.

Integral's operational framework is designed with stringent data security and compliance in mind. As a recognized public audit firm (Wirtschaftsprüfungsgesellschaft, WPG) under German law, it adheres to strict oversight by the Chamber of Public Accountants (Wirtschaftsprüferkammer). The company ensures GDPR compliance through defined access rights and documented procedures, processing all client data exclusively within European data centers and upholding professional confidentiality.

The strategic importance of this funding round extends beyond operational scaling. It enables Integral to accelerate hiring across critical areas, including AI engineering, licensed professional staff, and commercial teams. Furthermore, the capital will be directed towards enhancing automation for more intricate accounting, tax, and payroll workflows, and advancing the company's proprietary compliance intelligence. This positions Integral to further solidify its standing as a leader in the evolving landscape of professional services, where AI is increasingly augmenting human expertise.

The investment underscores a broader market trend where AI is not merely a tool but a foundational element for service delivery, particularly in highly regulated sectors. As Reid Hoffman noted, "Integral exemplifies AI's power to amplify human capability, especially in trust-dependent industries. Their model, where agents multiply the reach of licensed professionals, brings high-level financial expertise to SMEs, setting a precedent for the future of professional services." This Series A round, following a €6.3 million raise in February 2025 and the acquisition of cleverlohn, marks a pivotal moment for Integral as it expands its reach and refines its AI-driven service offering.
