Kupay

Kupay is a Madrid-based fintech that developed a one-click checkout for e-commerce. Shoppers can complete an online purchase without creating accounts, entering passwords or re-typing payment and shipping details, and merchants get higher conversion and less cart abandonment in return. Kupay sells the product to online stores as SaaS. Federico Sujoluzky and Jaf Aguiar founded the company in Madrid in 2021 and incubated it with Demium. In January 2022 it closed a €150,000 pre-seed round led by Demium's partner fund, with participation from business angels. In March 2023 it was acquired by Qoala, a cashback and coupons platform, which combined Kupay's one-click checkout with its cashback product.
