WHAT THE SEAL MEANS
Rigorous Validation
Startups with the DNFF Seal have passed 6–8 gates of brutal truth-testing. Customer validation, unit economics stress tests, competitive analysis, team capability audits, and more. Only 20% make it through.
Investor Signal
VCs and angels in the Nordics and Portugal recognize the DNFF Seal as a mark of serious validation. It tells them you've already done the hard work that most founders skip.
Permanent & Verifiable
Each Seal has a unique serial number and QR code. Anyone can verify its authenticity on this page. You can embed it in pitch decks, websites, and investor materials with full confidence.
Not a Guarantee of Success
The Seal means you passed validation at a specific point in time. Markets change. Teams change. Competitors emerge. The Seal proves you started on solid ground—everything else is execution.
