Building on Bedrock: A Practical Guide to Core & Ledger Choices in Embedded Banking

May 22, 2025

The most important architecture decision your fintech or bank will make? 

It’s not in a sprint ticket. It’s here.

Core and ledger infrastructure is the silent engine behind your fintech product’s roadmap. And the moment you choose one path over another, you define your speed, flexibility, compliance overhead, and long-term margins. 

But too often, that choice happens under pressure, with scattered opinions and jargon flying across a whiteboard.

This guide is built to change that.

What You’ll Get:

In this practical, plainspoken field manual, Ingo‘s CPO Lisa McFarland walks you through the real-world decisions product leaders and bank execs make when faced with modern embedded banking demands. 

Whether you’re launching a gig-pay platform or rethinking your BaaS architecture, this guide gives you the tools to think clearly, act confidently, and build smarter.

You’ll get:

  • A breakdown of the three dominant architecture models: Sidecar Cores, Middleware/BaaS Hubs, and Above-Core Platforms
  • A plain-English glossary that de-jargons terms like omnibus, tokenization, and sub-ledger
  • Real-world pros, pitfalls, and use cases for each architecture
  • A builder’s decision tree to help you map out your go-forward plan
  • Security + crypto readiness tips to stay audit-proof and future-proof
  • Practical checklists for both banks and fintech builders
  • A look inside Ingo’s own modular core approach

Who It’s For:

  • Fintech founders and product leads
  • Bank CTOs, CPOs, and transformation leaders
  • Embedded finance operators rethinking infrastructure
  • Anyone facing an architecture decision with real stakes
