For window businesses turning £1M+

One integrated sales and marketing engine — built exclusively to generate revenue.

We build the end-to-end AI-powered growth system that puts more homeowners into your pipeline, converts more of the ones already there, and reactivates the ones you thought were gone — automatically and consistently.

At your scale, leads falling through is not a minor inconvenience.
It's a revenue problem.

We work with businesses that have the leads coming in. The problem is what happens next — no reliable response process, no consistent follow-up, and no visibility of what's actually working.

The "quiet month" shouldn't exist.

Summer fills itself. It's the rest of the year that shows you where your lead generation and retention systems are failing.

Multi-location complexity.

Managing lead flow, conversion rates and team performance across multiple showrooms and 10–50+ staff requires more than a spreadsheet.

Revenue leakage.

If you're not responding instantly and following up for 12+ months, you're leaving verified revenue on the table every single day.

Growth isn't an accident.
It's a system.

We don't sell leads. We build the infrastructure that makes growth inevitable. Verified results from real window businesses.

We work with a very specific
type of window business.

Not every business is ready for what we build. Here's how to know if you are.

This is for you if
  • You turn over £1M+ and have a multi-team sales operation
  • You know leads are slipping through — but you lack the visibility to fix it
  • You're willing to change how the business operates to achieve scaling
  • You want predictable revenue, not seasonal guesswork or luck
This is not for you if
  • You want cheap shared leads with no internal follow-up process
  • You expect marketing to fix deep-rooted operational problems
  • You're not prepared to track conversion data at a granular level
  • You want to hand it over and forget it — that's not growth, that's gambling
Jamie, Founder of Window Growth Co.
"We do not scale chaos.
We only scale systems."

Window Growth Co. didn't start with a grand plan. At the end of COVID, I lost my job. The first business that took a chance on working with me was a window company. We got serious results, quickly — and six years on, they're still a client.

That longevity taught me something more valuable than any campaign metric: when you stay close to one sector, everyone wins. The lessons learned with one client make the next one sharper. The patterns become clear. The system gets better. And the clients benefit from six years of accumulated knowledge that a generalist agency simply can't offer.

So I made a deliberate choice to go narrow rather than broad. Not because I have a lifelong passion for windows — but because I understood that depth beats breadth when it comes to building something that actually works.

Window Growth Co. now exists to do one thing: build the growth infrastructure that established window businesses are missing. Not leads. Not ads. The whole system — from how you generate enquiries digitally to how fast you quote, how consistently you follow up, and how clearly you can see what's working.

Six years in one sector. A Chartered Marketer. And a first client who's still here.

That's not luck. That's what a system does.
