About

I'm James.

I build every system Roost Labs delivers, and I work with air conditioning businesses only.

01 — Why air conditioning

The install is the part that already works.

I narrowed down to this trade because of what I kept seeing inside these businesses. The fitting runs well — that part is skilled and it's handled. It's everything wrapped around it that leaks: enquiries landing at nine at night in the middle of a heatwave, a survey done on Tuesday and quoted at the kitchen table on Thursday, a job living across a notebook, a WhatsApp thread and an inbox at the same time.

The run from enquiry to install has enough of its own quirks in this trade — survey lead times, supplier waits, F-gas paperwork, grant eligibility — that general tools never quite fit it. You end up bending the business around the software.

So I build for one trade only. It means the systems already understand what a multi-split job looks like, why August runs differently from February, and what F-gas paperwork has to capture.

02 — What I'm building now

What I'm building now

I build enquiry handling, quoting and job tracking systems for UK air conditioning businesses. Four are in build right now — each scoped to a different bottleneck, because no two of these firms lose their time in quite the same place.

03 — How I work

You deal with me.

Not an account manager, not a support queue, and not a reseller of someone else's platform. The person who hears what you need on the call is the person who scopes it, builds it, puts it live and fixes it when something's off.

I take a small number of builds at a time so each one gets built properly. You'll know on the call exactly what I'd build for you and what it would cost.

Talk to the person who builds it.

Thirty minutes, no obligation. Worst case, you come away with a clear picture of where your week actually goes.
