Sunhat closes €9.2M Series A to tackle the “Proof Gap” for enterprises

Cologne-based Sunhat, the startup helping the enterprise automatically validate and share ESG and vital non-financial data, has closed €9.2 million in Series A funding. The round was led by CommerzVentures, with participation from existing investors Capnamic, EnBW New Ventures, xdeck, and WEPA Ventures.

Enterprises are fielding a growing volume of requests for policies, certificates, audit records, ESG metrics, and other compliance evidence, each with specific formats and deadlines. Although this information is produced daily, teams often struggle to find, verify, and present it when needed.

Research suggests employees spend roughly 360 hours a year searching for documentation, and about half of digital workers report difficulty locating required information. These pressures are intensifying as sustainability reporting and compliance become mandatory in more regions. With governance, risk, and compliance platforms projected to grow by $44.22 billion between 2025 and 2029, the ability to deliver instant, verifiable proof is becoming a meaningful operational and commercial advantage.

Sunhat provides an AI platform that converts ESG and compliance data into verified, ready-to-send documentation for customers, investors, lenders, and regulators. The need for proof is not new, but its scale now exceeds the limits of legacy processes. Large enterprises receive thousands of requests each month across supply chains, financing, and commercial engagements, creating manual workloads that drain productivity, slow decisions, and complicate trust building.

At the core of the platform is Proof AI, an intelligence engine trained on insights from thousands of successful questionnaires, audits, and assessments. It understands what counts as valid, verifiable proof for leading management standards, disclosure frameworks, and ESG ratings, and it maps those requirements to approved information companies already hold. The system learns continuously, refining rules and checklists over time.

Proof AI Agents connect to existing systems, such as SharePoint and other core business platforms, as well as specialised ESG, EHS, and quality tools. They capture new information as it appears, check for recency and completeness, and alert owners before anything expires or becomes invalid. When a questionnaire or audit arrives, the agents generate a verified, ready-to-send response in minutes instead of weeks.

The platform also scales across teams. Many customers begin with a single compliance or sustainability use case and then extend it to sales, legal, and procurement workflows.

The new investment will support Sunhat’s next phase of growth. The company plans to expand its team, advance Proof AI, add integrations and partnerships, and continue closing the proof gap by making verified evidence instantly available.
