Berlin’s Integral Closes €18M Series A to Build AI-Native Accounting Firm for European SMEs #
Integral, a Berlin-based startup offering accounting, tax, and payroll as a managed service rather than software, has closed an €18 million Series A round. The raise was co-led by LinkedIn co-founder Reid Hoffman and venture firm Mosaic Ventures, with existing backers Cherry Ventures, General Catalyst, and Puzzle Ventures all increasing their positions. The round brings Integral’s total capital raised to more than €30 million since the company was founded less than two years ago.
Lukas Zörner and Anil Can Baykal founded Integral in October 2024. Unlike conventional accounting software providers, the company is itself a licensed German tax advisory firm, Integral Tax GmbH, and delivers accounting, tax, and payroll services directly to small and medium-sized businesses through its own platform. AI agents handle invoice reconciliation, transaction posting, payroll processing, and tax filing, with licensed professionals reviewing and approving each output before it is finalised.
The company says AI agents now handle complete bookkeeping for more than half of its clients, compressing work that once took weeks into hours. Integral says the model is designed to address a labour shortage in Germany’s accounting and tax sector, where a shrinking pool of qualified professionals is struggling to meet demand from the country’s SME market.
Chandar Lal, Partner at Mosaic Ventures, said in the company’s announcement that AI makes it possible to address those workforce constraints by enabling new approaches to service delivery, rather than providing better software to existing providers. Reid Hoffman described Integral as a model for the next decade of professional services, one in which AI agents extend the reach of licensed experts so small businesses can access financial expertise previously available only to large corporations.
The Series A follows a €6.3 million pre-seed round completed in February 2025 and the November 2025 acquisition of cleverlohn, a digital payroll and HR provider, which brought Integral’s cumulative funding to roughly €12 million before the latest close. The company says all client data is stored and processed exclusively in European data centres.
Integral plans to use the proceeds to hire across AI engineering, licensed professional, and commercial teams, and to expand automation across accounting, tax, and payroll workflows and its compliance intelligence capabilities.
