What sets MX apart?

Accuracy

As proven in head-to-head comparisons, MX categorizes transactions with far greater accuracy than the competition.

Reliability

Unlike single-source aggregators, MX re-routes deficient connections so users don't lose access to their own account data.

Pricing

Whether you're a startup with three employees or an established company with thousands, MX gives you a financial edge.

Security

MX is SOC2 Type II compliant, PCI DSS compliant, and continually re-encrypts data to keep it safe.

Let your users access
all their data

The MX Atrium API enables your users to add all their accounts in one place. In addition, security measures such as multi-factor authentication are built directly into the process, giving your users the experience they deserve and building loyalty for your brand.
