Codion is a two-person studio. We build web and mobile products for clients, and ship our own.

Showreel

(01)Why Codion

We are two frontend engineers who spent years shipping interfaces for brands and startups. Codion is where we do that work under our own name, and where we build the products we wanted to exist. 

(02)What we do

Four things, done properly.

We keep the list short on purpose. These are the things we have done for years and do well.

(03)Before Codion

More than 70 projects, before this studio had a name.

Codion is new; the two of us are not. In earlier roles we shipped sites, platforms and apps for brands and startups, several of them award-winning. That work lives on our personal portfolios.

(04)Our products

We build our own, too.

Running products of our own keeps us honest about what it takes to launch, support and improve one.

Toneli

Your photo, better in one tap.

A photo editor for iPhone and Android. Pick a photo, pick a look, and Toneli does the rest: restore an old picture, remove a background, or turn a portrait into a sketch.

Create UI

Design faster. Build cleaner.

A Figma design system and an installable React component library that stay in sync, so what gets designed is what ships.

(05)How we work

A short path from idea to release.

  • 01

    Listen

    We start with the problem, the people who will use the product and what done looks like. You talk to the two of us from the first call.

  • 02

    Shape

    We agree on scope, architecture and a plan in plain language, then show early prototypes instead of long documents.

  • 03

    Build

    We work in short cycles with a preview link you can open at any time. The people who planned it are the people writing it.

  • 04

    Ship

    We launch, measure and tidy up. After release we stay around for the next round of work.

(06)The studio

Two people. That's the whole team.

No account managers, no hand-offs. You talk to the people who plan it, write it and ship it.
