OATHSPI

We remove the friction. You do the thinking.

A product studio in St Andrews, Scotland. We obsess over the details, argue about naming things, and create focused products that solve real problems — no bloat, no hand-waving, no "it works on my machine."

What we believe

Kill your features

If it doesn't earn its place, it gets cut. We'd rather ship something small and razor-sharp than bolt on one more toggle nobody asked for. Scope creep is the mind-killer.

Understand the problem

We don't start with the tech stack. We start with "what's actually broken?" Then we sit with it, poke at it, and design the simplest thing that fixes it. Solutions looking for problems aren't solutions.

Sweat the details

We care about the things most people never notice — until they're missing. Clean architecture, fast load times, interfaces that don't make you think. The craft is in the things you don't see.

Our approach

One product. One job. Done well. The world has enough bloated platforms trying to be everything to everyone. We make opinionated tools — deliberately scoped, obsessively refined, and fast enough to make you wonder what everyone else is doing wrong.

We stay close to the people who use our stuff. We're not fans of guessing what users need from behind a dashboard. We talk to them, ask dumb questions early, and make sure every decision is grounded in how the work actually works. The result is software people reach for instead of work around.

Introducing

Tome

Coming soon

A version intelligence editor for Microsoft 365. Tome is to .tome files what Word is to .docx — a specialised editor where version history, visual diffs, and approval workflows are built into the document itself.

See what changed, and who changed it

Visual diffs between any two versions. Block-level attribution that tracks every paragraph back to who wrote it, when, and in which version. Not "someone edited this on Tuesday" — real provenance.

Reviews that actually mean something

Structured multi-stakeholder approval with change-scoped re-review. Reviewers see only what changed since they last signed off — no re-reading the whole document to find what's new.

Your files. Your SharePoint. Our editor.

.tome files live in your OneDrive or SharePoint, governed by your policies. We don't store your data — we're just the editor. That's not a workaround. It's the architecture.
