Home / About
Sunfoxx was founded by people who grew up with unreliable power — where a working evening depended on whether the grid held. That's not a marketing line. It's why we build tools for the companies putting energy back in people's hands.
The company
Our core team has worked together since 2024, on one industry. In that time we've built roof-to-quote automation, geospatial pipelines, installer platforms and monitoring tools — the same problems, seen from enough angles to know where they hide.
We stay small and senior on purpose. Every person here has shipped solar software before, which is why scoping calls tend to be short and estimates tend to hold.
Where we work
Solar is a local business with global software problems. We're UK-based, work in English, invoice in GBP, EUR or USD, and schedule around your working day rather than ours.

How we behave
If a plan won't work, or a feature isn't worth building, you hear it in week one — not in the retrospective.
We turn down work outside solar and energy. Depth is the only reason to hire a specialist team.
Novel technology in the modelling layer. Proven, dull, well-understood technology everywhere else.
Everything in your repositories, documented well enough that another team could take over tomorrow.
Start a project
A 30-minute call is usually enough to tell whether we can help. If we can't, we'll say so and point you somewhere better.
