Plug & play systems for people who run paid ads with other people's money.
Tools and trainings built by a media buyer from over £2.2mil in real client ad spend. Ready-to-use assets you can deploy once and use forever. No theory, no 14-module course you'll never finish.

>Why this exists
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. I build these tools because I was sick of refreshing the glitchy app on my phone at 10:03pm on a Thursday, checking nothing had run away. The things that save me from sleepless nights (and hours dicking around in Ads Manager) 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.
>What we make
Every product here is one thing, done properly. Not a library you'll start and never finish.
Client-ready reports - spend, leads, sales, CPL, CPA and ROAS - emailed to each client, daily or weekly, automatically.
See it→An AI safety net for your Meta accounts. Pauses any ad, ad set or campaign that breaks your rules - even while you sleep.
Get >kill_switch→A flag, sent directly to you - the second an account pauses an ad or a CPL spikes, plus a one-line daily health check on each account.
See it→More on the way
New systems drop regularly - each one built on real accounts and handed over ready to use.
>You'll know before they do
The second something moves on a client account, a message lands. Not a 9am scramble - a heads up, like this:
That's >alert_pack. A flag, sent directly to you.
>Who it's for
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.
>Who's behind this
First, who I actually am - you shouldn't take advice on other people's money from a stranger on the internet (no matter how handsome they are). I'm a uni dropout who went into marketing instead and never left - 13 years now. Two daughters (6 and 7), a Goldendoodle the size of a small horse, and a coffee habit I'm not getting help for. Then again, I'd sooner go without than drink a Costa.
What I'm not is a guru. I'm a media buyer, in live accounts every day, and I started building these tools for the most selfish reason going: I was sick of doing the nervy, fiddly parts of the job by hand. Or more simply, for my own sanity.
My parents called me Nick, but everyone else knows me as Fish. I run Test Tube Marketing, a UK marketing agency. We've managed £2.2m+ in client ad spend and just picked up Marketing & Advertising StartUp of the Year at the 2026 Midlands StartUp Awards. 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 I don't use it to save myself time, money, and headaches, 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.
