About Hyperlayer

Hyperlayer is the intelligent banking platform built for the agentic economy: the financial control layer that sits above banks' existing cores, enabling next-generation Smart Accounts, without ripping anything out.

From a single integration, we give financial institutions a secure rules and orchestration engine that lets them design, launch and scale hyper-personalized products in weeks while preserving stability, compliance and control.

And there’s nothing like us anywhere in the world.

Hyperlayer works with Tier 1 and Tier 2 FIs across the UK, US, EMEA and Hong Kong, with an award‑winning UK consumer app (Hyper Jar) sitting in the group.

We’re creating the fintech category that every bank in the world needs: programmable, governed, agent‑ready accounts.

Your job is to make sure our audiences know that.
