“Can an Estonian Visa Principal Member become the go-to European alternative to Marqeta for embedded card issuing and BaaS?”
Wallester started as a small Estonian payment institution in 2018 and built a Visa Principal Member card-issuing platform, launching its White-Label product in 2021. It has since evolved from a pure card issuer into a broader embedded-finance infrastructure provider, adding multi-currency IBAN business accounts, BIN sponsorship, expense management and a free business tier. The 2026 UK EMI authorisation marks a deliberate expansion beyond the EEA into UK/Ireland/Switzerland coverage.
