''' Building an agency is mostly terrible.
There. I said it. It’s a thankless task of managing over-confident graduates, placating under-qualified clients, and constantly staring at a P&L that feels permanently on the brink of implosion. The entire model is a fallacy wrapped in a WeWork subscription.
You scale by hiring more people, which increases your single biggest cost base and, in turn, your operational fragility. Profitability rarely scales with headcount. More often, it’s the inverse. You win a big retainer, hire five people, the client churns six months later, and you’re left carrying the cost. It’s a miserable, high-stakes game of snakes and ladders.
I’ve spent years building Creative Marketing Group into the UK’s leading AI-first agency. We’ve been successful. But if I were to start a new agency from scratch, slated to launch in 2026, it would look absolutely nothing like the agency I run today. It wouldn’t look like any agency that exists right now.
It would be built on a single, brutal principle: zero-headcount delivery.
The Myth of Scale: Your Headcount is Your Biggest Liability
The traditional agency playbook is obsolete. It’s a relic of a pre-computational era. The model, preached by industry gurus and sold to aspiring founders, is to grow headcount as a proxy for success. A 100-person agency is seen as more successful than a 10-person one. It’s nonsense.
A 100-person agency is a 100-person cost liability. It’s 100 potential points of failure. It’s a machine built for inefficiency, where the core product (your team’s time) is sold in crude, unprofitable blocks called ‘retainers’.
Let’s be honest about the numbers. The average UK agency runs on a net profit margin of around 15%. Fifteen percent. You take all that risk, manage all those people, and endure all that client-induced stress for the same return you could get from a reasonably diversified stock portfolio. It’s a mug’s game.
The core flaw is the unbreakable link between work delivered and human hours spent. To do more work, you need more people. This linear relationship is a strategic dead end. The entire model is built on selling time, a resource that cannot be scaled efficiently.
In 2026, starting an agency that depends on a large, salaried workforce for delivery will be like launching a horse-and-cart business in 1920. You might find a few niche customers, but you are betting against the relentless, irreversible march of technology.
