About / the founder

I am Dean. I build the thing you were promised in the demo.

I spent twenty years building the funnels, stacks and teams that took SaaS businesses from £3M to £15M ARR. Then I watched company after company pay for AI that never made it past the demo. Operosus is me fixing that.

Not a strategy practice. Not a roadmap shop. I build working systems, wire them into your business and run them until they earn their keep. I am not a corporate guy and I do not use corporate words. I get shit done.

The first twenty years

Operator, not adviser

I built the funnels, the stacks and the teams that took SaaS businesses from £3M to £15M ARR. Quarter after quarter, with whatever tools existed at the time. I was the one accountable for the number, not the one presenting about it.

Then AI turned up

The demo problem

I watched company after company pay for AI that never made it past the demo. Impressive pilot, signed contract, six months later nothing in production. The money went to presentations about AI, not AI.

Now

Operosus is me fixing that

One founder, no account managers, no junior bench. I scope the system, I build the system, I run the system until it proves itself with output you can point at. And if your project should not exist, I will tell you that on the first call.

How I work

Four things I will not budge on

No AI hype

I do not sell the future. I build what works today, say plainly what does not, and never dress a demo up as a system.

Earned opinions

Twenty years of running marketing with real budgets and real targets. My advice comes from having done it, not from having read about it.

I do the work

The person you talk to is the person who builds. Your project never gets handed to a slide deck or a bench of juniors, because there is neither.

UK plain speaking

UK businesses, UK buyers, no waffle. I sell into the same market you do, so I will not dress a quote up in language neither of us uses.

The flywheel

How this business runs itself

Plenty of agencies recommend systems they have never run in anger. This is the wheel Operosus turns on, and every page, lead and case study on this site comes out of it.

Publish something useful. Search engines and AI assistants pick it up. Leads arrive, the work becomes systems, the systems throw off results and data, and the data tells me what to publish next. Round it goes, a little faster every lap. Contentwell does the publishing, Funnelwell tracks the leads, Emailwell works them. When I say a system will compound in your business, it is because this one is compounding in mine.

The loop this business runs on. Each lap is a touch faster than the last.
