Systems for people who run paid ads on other people's money.
Tools and training built by a media buyer who's doing the work on live client accounts right now. Build it once, run it forever. No theory, no 14-module course you'll never finish.
£2.2m+ in client ad spend managed · Marketing & Advertising StartUp of the Year 2026 · A working UK agency, not a course mill
Most of what gets sold to media buyers is strategy. Frameworks, mindset, the seventeen-step funnel. Some of it's even good. But none of it runs your accounts at 3am.
I run paid traffic on client budgets for a living. The things that actually save me time and money aren't courses - they're systems. Small, sharp tools I build once and let run.
So that's what this is. Media Buyer Systems is where I package up the systems I use myself and hand them over, ready to drop into your own accounts.
Every product here is one thing, done properly. Not a library you'll start and never finish.
An AI safety net for your Meta accounts. It watches every ad, ad set and campaign on the rules you set, and pauses anything that breaks them - on its own, around the clock. You build it once, inside your own account, in an afternoon.
The rest of the system
- Client Report Generator£247
Automatically emails each client a clean, client-ready report - daily or weekly - with their spend, leads, sales, CPL, CPA and ROAS. The reporting you dread, on autopilot.
- Email Alert Pack£47
A flag email the second an account pauses an ad or its CPL spikes, plus a one-line daily health check on each account. Never be the last to know.
Both available as add-ons when you get Kill Switch.
More on the way
New systems drop regularly - scaling next, then the other parts of the job you'd rather not do by hand. Same approach every time: built on real accounts, handed over ready to use.
This is for freelancers and agencies running paid traffic on other people's money, mostly for UK businesses. Live budgets, every day, where one runaway ad is a real problem and your reputation is part of the bill.
If you run your own ads for your own shop, plenty of it will still help. But it's built for the client-side grind.
I'm Nick 'Big Fish' Fisher. I run Test Tube Marketing, a UK paid traffic agency. We've managed £2.2m+ in client ad spend and just picked up Marketing & Advertising StartUp of the Year 2026. Mostly that means I've spent a long time running other people's money and learning exactly where it leaks.
Everything here is something I use on real accounts. If it didn't work, it wouldn't be for sale.
Start with Kill Switch.
It's the first thing to install - the safety net goes in before anything else. £27, one-time, running this afternoon.
