A small studio with a straight line from idea to launch

Chainline Studio is a design and development studio in Belgium. We build apps and websites for clients, and our own products, like ToppedUp.

What a chainline is

On a bike, the chainline is the line through the front chainring and the rear sprocket. When it is straight, the chain runs quietly and no energy is lost.

The logo is that drivetrain, with both centres on one line. Every project here aims for the same: a straight line from idea to launch.

Four rules for every project

Small and focused

A few projects at a time, each with full attention.

Show, then build

You click through a prototype before any code.

Built to last

Clean code and documented choices.

Measured after launch

The next step is based on real numbers.
