Why"Scale"IsUsuallyCodefor"Waste"

"We want to scale."

This is what brands say when they're happy with current performance and want more of it.

The problem is that "more" rarely works the way people expect.

How scaling actually works:

At £10k/month spend, you're hitting 5x ROAS. Great.

You increase to £20k. ROAS drops to 4x. Still profitable, but less efficient.

You increase to £40k. ROAS drops to 2.5x. The marginal spend is break-even or worse.

You increase to £60k. ROAS drops to 2x. You're actively losing money on the extra spend.

But the agency reports blended 2x ROAS and everyone calls it "successful scaling."

The maths nobody shows:

At £10k with 5x ROAS: £50k revenue.
At £40k with 2.5x ROAS: £100k revenue.

Looks like scaling worked. You doubled revenue.

But the first £10k generated £50k at 5x. The additional £30k generated £50k at 1.67x.

If you need 3x to break even, that extra £30k lost money. You scaled into loss.

Why agencies push scaling:

• Percentage-of-spend fees increase with spend
• Bigger numbers look better in case studies
• "Growth" is easier to sell than "efficiency"
• Clients often demand it regardless of economics

What smart scaling looks like:

Understanding your marginal ROAS curve. Knowing exactly where efficiency drops below profitability. Spending to that point and not beyond.

Sometimes that means staying at £10k. Sometimes it means the opportunity is at £100k. The answer depends on your specific economics, not on the desire to "grow."

We'd rather manage a profitable £10k than an unprofitable £100k.

That's not exciting. It's just correct.
