Paramount Commerce

Back in the early 2000s, we achieved something that had never been done before. We launched the first product for consumers to make online purchases directly from their bank account without the need to fund an e‑wallet. Since then, we continue to deliver industry firsts; we were the first to process a regulated sports betting payment in the U.S. and the first to offer real-time withdrawals to a bank account in the gaming industry. Today, we provide industry-leading bank account-based payment solutions and AI risk management in a single solution. Since cornering the iGaming and sports betting market in Canada, we’ve expanded to provide real-world value to international remittance merchants, digital wallets, eCommerce companies, and more. We are proud to create raving fans of both merchants and consumers.
