Integral, a Berlin-based company building an AI-native platform for accounting, tax and payroll services, aimed at small and medium-sized businesses, has announced an €18m Series A funding round.
The round was co-led by Mosaic Ventures and investor Reid Hoffman, with participation from existing backers Cherry Ventures, General Catalyst and Puzzle Ventures, all of whom increased their stake in this round.
The fresh capital takes Integral’s total funding to more than €30m, achieved in under two years since the company was founded.
Integral’s model pairs its technology with Integral Tax, an affiliated licensed professional services firm that runs entirely on the platform. AI agents handle reconciliation of invoices and bank transactions, prepare account postings, payroll runs and tax filings, while licensed professionals at Integral Tax review, exercise judgement on exceptions, and take legal responsibility for everything that is filed or submitted. Corrections made by professionals feed straight back into the system, a loop the company says continually sharpens its automation.
Since the start of 2026, the professionals at Integral Tax have doubled the number of clients each can serve, and the company reports that monthly accounting turnaround for many clients has fallen from weeks to hours, while filings continue to be reviewed and signed off by accountable professionals throughout.
The founders describe Integral as one of the first companies in what they term “AI-native services”, businesses that deliver a regulated outcome directly, rather than selling software tools to existing service providers. They argue that licensing, professional secrecy and personal liability rules make clear exactly where a human must remain in the loop, allowing everything else to be automated with confidence.
The company intends to use the new funding across three areas: extending automation to more complex accounting, tax and payroll cases; hiring across AI engineering, licensed professional and commercial teams; and developing additional services beyond its current accounting, tax and payroll offering.
Mosaic Ventures partner Chandar Lal said, “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.”
Integral investor Reid Hoffman 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 Lukas and Anil are building it where the bar is highest: Germany.”
