I use just one system.

Most founders overcomplicate content.

They think they need 100 ideas a week to win on LinkedIn.

BS.

I use just one system.
I call it: The Content Waterfall Systemℱ

Here’s how it works 👇

→ Record a short Loom video (2–5 mins)
→ Transcribe it with ChatGPT
→ Turn it into a newsletter + 3 LinkedIn posts

That’s 1 idea → 4 assets.
All in under 30 mins.

Now do that 3x a week and you’ll build a content machine.

Not a hamster wheel.

I’ve recorded 250+ Looms this way.
Each one feeds my daily newsletter, LinkedIn, and GrowthKit library.

If you’ve got thoughts in your head, you’ve got content.

You just need a system to extract it.

I teach this inside GrowthKit.
It’s all inside the Content module of The 4 Cs Flywheelℱ.

Success

Success isn’t just revenue.
It’s time.

Time to spend time with my fam.
Time to make lunch at home.
Time to sit in the garden with a coffee (and my cat).
Time to choose when to work — and when to shut the laptop.

In my agency days, I chased numbers.
$60k MRR. Big clients. Bigger team.
But I was always on. Always stressed.

Now?

→ I run GrowthKit solo from home.
→ I work smart, not long.
→ I prioritise freedom over fluff.

The photo attached isn’t some “look at me” post.
It’s a reminder of why I built this life.

Every system I teach inside GrowthKit?
It’s built to buy back time.
To help other founders choose freedom over burnout.

Because what’s the point of scaling if you’re miserable while doing it?

COVID

MailNinja lost a chunk of its revenue overnight when COVID hit.

Campaign work dried up.

So I did what most founders avoid


I productised everything in sight.

→ Turned my services into flat-fee packages
→ Swapped bespoke for standardised
→ Moved from client chaos to controlled systems

Within months, I launched training, coaching, and eventually
 GrowthKit.

And here’s what I realised:

đŸš« Productising doesn’t mean less value
✅ It means more clarity for your buyer
đŸ”„ It means building once and selling 100x

Most agency owners stay stuck because they won’t let go of their custom service mindset.

I was one of them.

But once I made the shift, I scaled fast — and finally got my time back.

Inside GrowthKit, I show you how to do this too.

There’s an entire course called The ‘SCALE’ Setup Plan that walks you through the exact steps I used.

If you’re tired of repeating yourself, quoting custom work, or relying on feast-and-famine sales cycles


It’s time to productise.

Took me 15 years to figure it out.

Don’t wait that long.
