Who we are

End of Line Software, Inc. is a small consultancy in Canada. We build SaaS, the platform underneath it, and the applied AI inside it — for teams who care how a system ages. The name is a nod to EOL — the boundary between one line of code and the next. Beyond that boundary is where we work: choosing projects that make real, day-to-day differences in people's lives, and handling the engineering that keeps them running.

Matthew Marion

Founder of End of Line. Started in customer support — an experience that still shapes how he works: listen first, build what actually helps. Spent years as a senior engineer on a multi-million-user SaaS product, working on the parts of the system that decide whether it can be trusted at scale — identity, performance, and the operational layer that holds up under load. From there, into the platform and tooling work that quietly makes engineering teams faster and incidents shorter.

More recently, shipping production AI inside real products — not demoware, but the kind that has to keep working in front of paying customers.

// how we work

Operating principles

We start by listening, not pitching.

The first job in any engagement is to understand what you actually need. Sometimes that is what you asked for; often it is something next to it. Either way, we are not useful until we have done the work to find out.

We own outcomes, not hours.

A project is done when it works, not when the time runs out. If we are wrong about scope, we say so.

We write code for the engineer who reads it in three years.

That engineer is often us. Boring, well-bounded code beats clever code that nobody wants to touch.

We say no to projects we cannot do well.

A small studio is only useful if its judgment can be trusted. We turn down work outside our depth.

We work in the open with our clients.

Shared repos, shared docs, shared decisions. Nothing useful happens in a black box.

Done means tested and green.

Tests come before code, then the code that makes them pass. CI green before review, before merge, before deploy. Untested work is not done — it is owed.
