Every app we make is its own world.
One founder. Many worlds. Commercium is an independent app studio in London.
We make apps. Each one gets its own look, its own voice and one clear job.

369 Zone
A daily 3-6-9 writing ritual that keeps one intention in front of you.
- Write one intention: three times in the morning, six at midday, nine at night.
- Streaks and a 21-day tracker turn the ritual into a habit.








- A breathing exercise to settle before every session.
- Home Screen widgets and reminders at the hours you choose.
- AI suggestions you can edit, refine or replace. The words stay yours.
How we work
Make what should not be possible for one person.
- 01
Start with the idea, not the team
We use technology to reduce the work it takes to turn an idea into a finished product. AI agents, coding assistants and automation handle what can be systematised; the founder stays responsible for the direction, the judgement and the final result.
- 02
Measure before we assume
We treat products as experiments. We build, observe, test and change them based on evidence rather than intuition alone. A release is not the end of the process; it is another source of information.
- 03
Use machines for leverage
AI is not the product philosophy. It is part of the infrastructure. We use capable tools to extend what one person can research, design, build, test and run, while responsibility for the work stays human.
Every app we make is its own world.
