PayWiser

What PayWiser does

PayWiser d.o.o. is a regulated Electronic Money Institution (EMI) headquartered in Ljubljana, Slovenia, founded in 2017 by an international team with payment and financial-technology expertise. The company operates an API-first platform spanning payment account services, card issuing (virtual and physical Mastercard debit), payment acquiring, BIN sponsorship, white-label card programs, and on/off-ramp services for digital platforms. Its core technology is a unified API gateway for payment processing, clearing, settlement, and reconciliation, supported by web and mobile applications for end-user self-service and by direct enterprise integration for partner programs.

PayWiser is licensed by the Bank of Slovenia (license No. 0.04.5.4-5/2020-70 dated November 2, 2021) to issue electronic money and provide payment services across the EEA, and holds PCI DSS Level 1 certification. It is a principal member of Mastercard, enabling direct BIN sponsorship for clients that want to issue cards without becoming Mastercard members themselves. Banking rails are provided through CentroLink (Lithuania) and Hranilnica LON (Slovenia, for safeguarded customer funds under the local Deposit Guarantee System), with KYC/AML and fraud controls delivered via Sumsub, ComplyAdvantage, and WebShield. Apple Pay and Google Pay extend cardholder reach, and Austria Card handles physical card production and personalization.

PayWiser serves both end consumers (payment accounts and debit cards for personal and business use) and enterprise clients (merchants, platforms, marketplaces, and solution providers seeking white-label card programs, BIN sponsorship, or on/off-ramp wallet funding). Revenue is transaction-based for card issuance, acquiring, BIN sponsorship, and MoneySend transfers, with account-related fees defined in a published Price List. Distribution is hybrid: API self-serve for SMBs and individuals, partner/reseller channels for mid-market reach, and direct enterprise sales for white-label and BIN sponsorship engagements. No external funding or revenue figures are publicly disclosed.
