MEASURABLE RESULTS
Business Outcomes of Portable Loyalty
Decentralized Identity (DID) transforms loyalty programs from isolated silos into interoperable assets. Here’s what our DID-powered loyalty portability delivers for your business.
01
Increased Customer Lifetime Value (LTV)
Portable loyalty points become a user-owned asset, increasing perceived value and reducing churn. Customers engage 3-5x more frequently when they control their rewards across brands.
40-60%
Higher Retention
3-5x
