A few of the things we've built. Some clients prefer to stay unnamed - we respect that, the work speaks anyway.

How we work
Clear phases, from first meeting to launch.
It starts with a free 30-minute call. Then, the timing of a typical first milestone: you always know what we're building and what comes next.
- Day 1
Plan
After the free call, we set goals, priorities and a fixed-price milestone plan together.
- Week 1
Prototype
A clickable prototype with your real data, to try right away with the people who'll use it.
- Weeks 2–3
Launch
We build the final version: tested, monitored and published on your servers or ones we pick together.
- Ongoing
Grow
Fine-tuning, performance and handover of the code with documentation - or we stay on by your side.
Senior by default. Predictable by design.
No junior hand-offs
Every line is written by senior engineers with years of production software behind them. The people you meet are the people who build.
Direct access to the builders
No account managers, no layers of bureaucracy, no playing telephone. You communicate directly with the senior engineers building your product via shared Slack or Teams channels.
Fixed scope, fixed price
Clear milestones and predictable budgets. No open-ended hourly billing or scope surprises.
Seamless handover or long-term partner
Walk away with a tested, well-documented codebase, or keep us on to grow alongside your team. You dictate the terms.
Let's ship something

Answer a 2-minute questionnaire, then we set up a 30-minute call: we talk through your project, scope a first milestone and tell you honestly if we're the right team.
