Headless, API-first

Your business rules are buried in your screens.

So every new front end, channel or agent rewrites them. We build the APIs that serve every rule your application runs on, so everything new calls the same logic.

What you get

One set of business rules, served to every front end.

Every screen, channel and agent calls the same APIs.

Clean APIs

  • Business logic moved into services
  • API contracts, with tests for every rule
  • Delivered module by module, in your repos

Every rule, found

  • Rules pulled out of screens, services and batch code
  • Each one traced to its file and lines
  • Verified by experts who know your domain

Change the screens, keep the rules

  • New front ends built on the same APIs
  • Web, mobile and partner channels on one set of rules
  • Coding agents that call your real business logic
How we get there

Clean APIs, built on every rule we find.

Every step stands on the grounding layer: a verified map of your system, kept in sync with your code.

Week 1

Grounding sample

In one week we build the grounding layer on a sample of your code, so you see what we can do on your own system.

Then

Find every rule

We reverse engineer the logic in your screens and back end, and trace every rule to the line it lives on.

Then

Build the APIs

Our engineers and agents move the logic behind clean APIs, module by module, with tests that show it behaves as before.

How it fits together

Your APIs, built on the grounding layer.

The APIs serve your business logic to every front end and agent. Underneath, the grounding layer keeps each rule traced to its code and in sync as the code changes, so your engineers and agents keep building on solid ground.

  • Every rule kept, verified before it moves.
  • Old and new side by side until each part is switched over.
  • Agents work from facts: the same rules, served over MCP.

You own what we build; we're there when you want to go further.

After the project, the grounding layer lives on in the Swimm platform

Frequently asked questions

What does headless mean for our system?

Your business logic moves out of the screens and into services with clean APIs. Every front end, channel and agent then calls the same rules, and you can change the screens without touching the logic.

Do we have to rebuild the front end at the same time?

Your current screens can call the new APIs, and new front ends can follow when you're ready.

Can the system keep running during the move?

Yes. We move the logic module by module, so old and new run side by side until each part is switched over.

Where do we start?

With a scoping call, then a grounding sample: in one week we build the grounding layer on a sample of your code, so you see what we can do on your own system.
