SSilk Cashback
Silk Cashback is a Madrid-based fintech that describes itself as "the performance layer for physical commerce": it turns bank and neobank apps (including a partnership with Revolut) into a distribution channel for brick-and-mortar merchants via card-linked cashback and loyalty offers, attributing real card purchases to campaigns so merchants pay only for verified incremental in-store sales. Founded in December 2023 by three second-time founders who previously exited proptech SaaS Arextech (acquired by Architrave), the company originally launched as "Silk | Cashback for Rent", a loyalty programme letting tenants earn points on rent payments, and has since pivoted to retail/merchant cashback across a reported 45,000+ Spanish physical retailers. It won Mastercard's For Fintechs Iberia 2025 competition (announced under the name "Silk Pay").
