The story
Founded in 2018 in Estonia, Montonio began as a checkout and payment initiation solution focused on Baltic e-commerce markets. The company expanded from open banking / PIS payments into card payments, BLIK (Poland), shipping logistics, and embedded BNPL/financing — becoming an all-in-one checkout-and-logistics platform for SMB online merchants. Its most recent moves include replacing Stripe with Adyen for card processing and launching revenue-based merchant financing, signaling a push toward becoming a merchant financial OS in the Baltics and Poland.
