Unlike other providers, our multi-sourced solution ensures that you always have the most reliable account information despite a broken connection. Give your customers a complete view of their finances alongside a world-class digital experience.

Enhanced Transaction Data

Our industry-leading cleansing and categorizing technology is applied to all your users transactions. By establishing a foundation of transactional data that is both consumable and actionable, you can lead tomorrow’s innovation and create a configurable UX for your end-users.

Instant Account Verification

Unlike micro deposits, that take three to five days to verify users’ account and routing number information, Instant Account Verification confirms that information in seconds—eliminating lost revenue, account abandonment, and providing an enjoyable experience for account holders.
