That'sKey

🔑 Coming soon — building in public

Everyday problems have a key.
We build the tools that turn it.

That'sKey is a home for small, sharp tools that quietly remove friction from everyday work — at your desk, in your inbox, across the apps you already use.

Get early access See what we're building

Most software makes you adapt to it. We think it should be the other way around — one small, well-made tool at a time, until the everyday friction of work simply disappears.

What We Do

A growing family of tools under one roof

Not one product — a portfolio of focused assistants and utilities, each built to solve one real, recurring problem, really well.

💬

Knowledge & docs, made conversational

Turn sprawling internal wikis and documentation into something you can simply ask a question — and get a straight answer.

☁️

Cloud & infrastructure copilots

Assistants that sit alongside complex platforms and cloud consoles, translating dense configuration into plain instructions and safe actions.

🤖

Conversational assistants

Chat-first tools that plug into the way teams already communicate, handling questions, requests, and busywork without a new app to learn.

⚙️

Workflow automation

Small pieces of glue that connect the tools you already use, quietly removing the repetitive steps nobody enjoys doing by hand.

📊

Clarity from data & documents

Utilities that read the boring stuff — spreadsheets, reports, forms — so people don't have to, and surface what actually matters.

🧩

...and more, one problem at a time

Every new tool starts from one everyday annoyance worth fixing. If it's useful enough to keep, it earns a permanent place under the umbrella.

Our Approach

Small tools. Sharp focus. Real use.

The philosophy behind everything we ship.

Find the friction

We look for the small, everyday annoyances people have simply learned to live with.

Build the smallest useful thing

No bloated platforms. Just a focused tool that solves one problem well, from day one.

Fit into existing workflows

Our tools meet people where they already work, instead of asking them to move.

Keep what earns its place

Every tool has to prove it's genuinely useful — and if it is, it stays and grows.

About

The founder

Mark Ambrodji

Founder, That'sKey

Born in Russia, now a Danish citizen living in Denmark — Mark started That'sKey to build the kind of small, practical tools he kept wishing existed at work.

The name is a personal detail hiding in plain sight: said with a Russian accent, "that's key" sounds like датский (datskiy) — Russian for "Danish." The logo carries the same idea: its D and transformed k form DK, Denmark's country code. A name and mark that carry a bit of the story — and the belief that the smallest detail can turn out to be exactly the key.
