Clearing & Custody

Apex is a digital clearing and custody engine that’s powering the future of fintech.

We were one of the first companies to digitize the activities associated with securities clearing and custody so financial services providers can have the speed, efficiency and flexibility they need to deliver better investor experiences.

When we work with you, our sole focus is on facilitating the relationship between you and your customers. So you can rest assured that you won’t be competing with Apex retail locations or investment products, but you will get the benefits of our private backing, deep capitalization and a proprietary enterprise-grade technology platform with the throughput and scalability required by fast-growing, high volume companies.

As a custodian, Apex is responsible for holding and safekeeping investor assets.
