Duna has raised a 30 million euro Series A led by CapitalG, the growth investment arm connected to Alphabet. This brings its total funding past 40 million euros after a 10.7 million seed round. The round also includes participation from Index Ventures and Puzzle Ventures.

This is a category that rarely gets headlines. Business identity verification lives inside compliance and operations, yet it directly affects how fast regulated platforms can onboard customers and start generating revenue.

The problem Duna is solving

Verifying business customers is rarely straightforward. It involves corporate registries, beneficial ownership checks, document reviews, and frequent manual intervention. For many fintechs and regulated platforms, this creates slow onboarding flows, back and forth with customers, and internal operational burden.

Duna builds software to handle know your customer and know your business requirements with a higher level of automation. The aim is to reduce manual work and improve onboarding efficiency for companies that need to verify other businesses.

The founders previously worked at Stripe, where they led infrastructure teams. Their experience with building financial infrastructure at scale shaped the view that business identity checks are still handled through fragmented tools and manual processes.

Early customers include Plaid, CCV, Moss, Bol, and SVEA Bank. Their adoption points to a shared operational challenge across platforms that onboard businesses at scale.

Why the Series A matters

A 30 million euro Series A for a company focused on business identity infrastructure is notable because it highlights investor interest in compliance tooling that sits deep in enterprise workflows.

CapitalG’s involvement signals confidence from investors familiar with large scale fintech infrastructure. Continued backing from Index Ventures and Puzzle Ventures adds further credibility from funds that have supported many fintech companies through growth stages.

Duna plans to use the funding to expand its enterprise capabilities and to work toward a broader vision. The idea is that once a company’s identity and its stakeholders are verified, this information could be reused across platforms instead of being repeatedly checked from scratch.

If this approach matures, onboarding may become less of a hidden friction point and more of a predictable, manageable process for regulated platforms.

Key takeaways for fintech startups

A few points stand out for founders and operators working on regulated products:

• Business identity verification remains a major operational bottleneck for platforms that onboard corporate customers.
  
  
• Automation in know your customer and know your business processes can directly affect onboarding speed and internal workload.
  
  
• Adoption by established platforms shows this is a recurring, practical problem rather than a theoretical one.
  
  
• Investor interest in this space reflects the value of solving difficult compliance challenges inside core workflows.
  
  
• The concept of reusable business identity could reduce duplicated effort across platforms over time.
