• With offices in Berlin and London, the startup raised €12 million in a seed round led by Dawn Capital. One of its angel investors is the former global head of audit at KPMG.
• Cortea’s AI agents reviewed more than 4,000 audit reports in a single season and flagged issues in every one.
• This funding arrives at a time when UK audit firms are under greater regulatory pressure to improve quality, and AI is being adopted more quickly in professional workflows.

Audit firms often spend months checking financial statements, disclosure notes, and company filings before signing off, but mistakes still happen. In the latest audit season, Cortea’s AI agents reviewed more than 4,000 audit reports and found issues in every single one.

This number highlights Cortea’s main selling point: its AI accelerates audits and identifies issues people might miss. Today, the company announced a €12 million seed round led by Dawn Capital, with Cherry Ventures, Mosaic Ventures, and angel investors, including Larry Bradley, the former global head of audit at KPMG, also participating.

“The audit profession is about to undergo one of the biggest shifts in its history. AI will transform how audits are executed, but it will also raise the bar for quality, consistency, and professional oversight,” says Valentin Neumann, co-founder and CEO of Cortea.

Who is behind Cortea?

Cortea was founded in 2024 by Neumann, who was chief technology officer at hearing aid company Audibene, and Philipp Hövelmann, who worked on the development team at crypto startup Finoa.

The founders met at university and started Cortea after seeing how manual and error-prone the audit process can be. The company is based in Berlin, works across the UK, and plans to expand into the US and Germany.

UK audit reform has been underway for years, and the Financial Reporting Council has increased its focus on audit quality following major failures. Firms now deal with more regulatory pressure and limited capacity, which is the gap Cortea wants to fill.

“Every audit firm is exploring how AI can improve the way audits are performed. The firms that succeed will be those that can combine the efficiency of AI with the rigour and trust that the profession demands. Our mission is simple: help audit firms use AI with confidence,” Neumann adds.

How the technology works

Cortea’s product is designed specifically for audit review. Its Audit Quality Agents look at audit reports, financial statements, disclosure notes, and workpapers in the final stages before sign-off. They check figures and disclosures against supporting documents to spot inconsistencies, Companies House filing errors, and possible compliance problems.

For a mid-sized firm, this review usually takes auditors several days, but Cortea’s agents do it in minutes.

“In audit and assurance, trust is everything. If AI cannot improve quality, transparency and professional judgement, it has no place in the audit process. Cortea is different because it is built for how audit firms actually operate. Cortea integrates AI into the audit process in a way that is controlled, traceable and practical. That is what the profession needs now: not more AI experiments, but technological innovation that firms can trust,” Bradley notes.

A competitive market with a clear focus

The global AI in audit market was worth $1 billion in 2023 and is expected to reach $11.7 billion by 2033, growing at almost 28% each year.

AuditBoard, which Hg bought in 2024 after it raised over $200 million, focuses on the wider audit management sector. Workiva offers compliance and reporting tools for listed companies, and TeamMate, owned by Wolters Kluwer, is popular with internal audit teams.

Cortea stands out by focusing just on the final review stage of external audits, which is the riskiest time before a report is filed, instead of managing the whole audit process.

Dawn Capital has invested in other enterprise software companies such as Collibra, Quantexa, and Showpad, all of which grew from European startups into global leaders. Dan Chaplin, a partner at Dawn, said the firm believes Cortea will be “at the forefront of this transformation, helping their partners not only to meet demand and scale capacity, but to improve quality at every step.”

The fresh capital will fund more audit agents, improved integration with existing audit platforms, and growth in the UK, Germany, and the US. Cortea had already raised €3.1 million in a round led by Cherry Ventures, bringing its total funding to about €15.1 million.

A bigger question is whether quality-layer AI, which checks AI-assisted work, will become a standard part of professional services. If 4,000 audit reports had issues that almost went unnoticed, the answer might already be obvious.
