Build, Launch, and Scale
with APIs Built for Fintech
Whether you’re launching from scratch or scaling an existing product, AET’s modern API infrastructure powers custody, simplifies compliance, and builds investor trust—so you can stay focused on growing your customer base.
A Modern Custodian That Won’t Hold You Back
Many custodians claim to be tech-forward. But under the hood, they’re still running on legacy infrastructure with bolted-on APIs. AET was built differently. Our custody stack is modern and flexible, designed to embed into your platform. We empower you to offer a best-in-class investor experience, without wrestling with outdated tools or waiting on vendor roadmaps.
