Case Study: Wundertax achieves a 95% approval rate with Sumsub

Wundertax Reaches a 95% Approval Rate After Switching to Sumsub

wundertax, a German fintech tax-return platform for expats and other specific user groups, needed to automate more of its identity verification process while reducing manual effort and improving fraud detection. Before Sumsub, the company relied on a less automated solution that required too much technical and operational involvement.

Sumsub implemented an automated verification flow for wundertax that included document upload, liveness checks, and phone verification. The integration took less than three weeks, and wundertax quickly achieved an approval rate above 95% with a median processing time of 10 seconds, while also improving efficiency, security, and fraud prevention.
