Integral, a Berlin-based technology company focused on accounting, tax, and payroll services for small and medium-sized enterprises, has announced an €18 million Series A funding round. The investment was co-led by Mosaic Ventures and Reid Hoffman, with participation from existing investors Cherry Ventures, General Catalyst, and Puzzle Ventures. The round brings Integral's total funding to more than €30 million since the company was founded in 2024.
A Response to Germany's Accounting Talent Shortage
Germany's accounting and tax sector faces a worsening shortage of licensed professionals, which places pressure on small and medium-sized businesses that need compliant financial services. Integral addresses this challenge by combining licensed tax professionals with AI engineers to deliver accounting, tax, and payroll services directly. The model is designed to increase the number of businesses that each professional can serve without reducing quality or control.
How the Platform Works
Integral Tax, an independent licensed German audit and tax firm affiliated with Integral, operates entirely on the company's platform. Integral's proprietary fleet of AI agents handles repetitive work across bookkeeping, tax, and payroll, including reconciling invoices and bank transactions, creating account postings, and preparing payroll runs and tax filings. Licensed professionals remain in full control by reviewing and signing off on every result.
Tangible Efficiency Gains
Integral reports that its AI agents now prepare bookkeeping end to end for more than half of its clients. This has reduced average monthly accounting turnaround from weeks to hours, and since the beginning of the year, professionals at Integral Tax have doubled the number of clients they can serve. Every review by a licensed professional feeds back into the platform, which allows the automation to improve with each client served.
Investor Confidence and Strategic Use of Funds
The Series A funding will accelerate hiring across AI engineering, licensed professionals, and commercial teams. Integral also plans to deepen automation across complex accounting, tax, and payroll workflows and advance its proprietary compliance intelligence for regulated financial work. Investors framed the round as validation of an AI-native services model that multiplies the reach of licensed professionals.
AI-Native Professional Services
Integral is positioning itself as a leader in the emerging AI-native professional services category rather than as a software vendor for accounting firms. Reid Hoffman said the company shows how AI can amplify what people can do in a highly regulated and trust-dependent industry. He noted that agents multiply the reach of licensed professionals so small businesses can access expertise once reserved for large corporations.
Leadership Comments
Lukas Zörner, co-founder and CEO of Integral, said software does not file business taxes, run payroll, or sign annual accounts. He emphasized that licensed professionals perform these tasks and that their numbers are declining each year. Instead of building another tool for professionals, he said Integral built the firm itself with AI agents doing the work and licensed experts standing behind every result.
Investor Perspectives
Chandar Lal, partner at Mosaic Ventures, said AI makes it possible to rebuild industries from the ground up rather than simply selling better software. He pointed to obvious labour shortages in accounting, tax, and payroll and said Integral is uniquely positioned to solve that problem in Germany and beyond. The investor view reflects growing confidence in service delivery models built around AI rather than traditional software adoption.
With its latest funding, Integral aims to extend automation across the full accounting, tax, and payroll lifecycle while expanding its team of engineers, licensed professionals, and commercial staff. The company's early results suggest that AI can meaningfully reduce administrative burden without removing human oversight. As Germany's professional services sector grapples with fewer licensed practitioners, Integral's model offers a potential path toward more scalable and reliable financial services for small businesses.
