About Sumn

We built the thing we wished existed.

Our story

Sumn started with a simple question: why is it so hard for a team to silently reach each other?

In small practices and offices everywhere, staff work in separate spaces — a reception area here, a consultation room there. Staying connected across those spaces shouldn't require a phone call, a shout across the corridor, or an expensive enterprise system with features no small team will ever use.

So we built Sumn. A Windows app. A flat fee. No drama.

It installs in minutes. Enter a licence code. It finds the other computers on your network automatically. And then it just sits there — quietly, transparently — ready the moment your team needs to connect.


Who we are

We're a small team.

We're not a faceless SaaS company — we're people who care about getting this right, and we're reachable when you need us.


What we believe

Three things we won't compromise on.

Simple

Install it, enter a code, it works. If it needs more explanation than that, we've built it wrong.

Reliable

It has to work when it matters. Every click, every time.

Fair

$500 for a whole site. We're not here to extract value. We're here to provide it.
