We turn ideas into digital products.

Product, design and development on the same team to define the direction, build and reach production. It may be a new product, a system for your company or the next stage of something that already exists.

The studio

An idea only becomes a product when someone owns the whole journey.

Sothen brings product, design and development together to turn an early need into something people can use. The same team takes part in defining, prototyping, building and launching it.

We are a small team of partners and take on a limited number of projects at once. That keeps decisions close to the people doing the work and prevents context from getting lost between sales, planning and delivery.

What we build

Three starting points, one path to production.

We join when there is still an idea to shape, when a company needs its own system or when an existing product has stopped moving forward.

Create
A digital product from scratch
We turn an idea into a product definition, prototype, working software and launch without requiring a technical team on your side.
Build
Software for your company
We build custom systems when spreadsheets, disconnected tools or generic software no longer support the work.
Unblock
Take over an existing system
For software that became fragile, stalled or too dependent on one team or supplier. We stabilize it first, then plan what comes next.

Method

From idea to a product in use.

The depth changes with each project. The sequence keeps decisions visible and reduces the risk of building the wrong thing.

01
Diagnosis
We understand the problem, the audience, the constraints and what must be true for the product to be worth the investment.
02
Design
We turn the idea into flows and a navigable prototype to align the product before the definitive build.
03
Build
We deliver working versions frequently and prepare integrations, publication or rollout according to the product.
04
Ownership
We agree on ownership, access, documentation and continuity so the product can move forward with or without Sothen.

Work

We build software and live with what happens after launch.

After launch come security, support, infrastructure, cost and continuous improvement. These are the parts a portfolio of screens does not show, and the ones that decide whether a product survives.

Team

A small, senior team directly responsible for delivery.

You work with the partners who define, design and build the product. We take on a limited number of projects at once to keep decisions close to the people doing the work.
