About
A studio small enough to care, experienced enough to deliver.
Indigo 42 is a Lincoln-based studio built around two crafts, design and engineering. We’ve shipped work for global brands and local businesses alike, and the same care goes into both.

What we believe
The work is the pitch
No jargon, no theatre. We’d rather show you something working than talk about it.
Fast is a feature
Every second of load time costs you customers. We build for speed from day one.
Built to last
Not just launch day, but year three. Maintainable code, systems your team can run.
