Owning the Full Stack: Why Agencies Must Become Product Companies
Most marketing agencies are already dead. They just haven't realised it.
They continue to sell time, trade hours for pounds, and celebrate retaining clients on bloated retainers for another year. They are polishing brass on a sinking ship, oblivious to the fact that the hull has been ripped open by a force they refuse to understand: the fundamental shift from service to product, driven by agentic AI.
The model is broken. Selling people's time is the least scalable business model ever conceived. It’s a linear equation: to earn more, you must hire more. More headcount, more management overhead, more office space, more problems. The maths is brutal, and it leads to a ceiling you will inevitably hit.
I’ve lived that reality. I’ve seen the P&L of countless agencies. After you’ve paid for the expensive office in Shoreditch, the legion of account managers, and the licence fees for a dozen SaaS tools that don't talk to each other, what’s left? If you’re lucky, a 15% net margin. For most, it's closer to single digits. All that stress for a return a passive index fund could beat.
To survive the next decade, agencies must stop thinking like agencies. They must start thinking like tech companies. They must evolve from pure service providers into product owners who own the full stack of value delivery. This isn't a controversial opinion; it's an economic inevitability. The agencies that build proprietary technology will build defensible, scalable, high-margin businesses. The rest will compete to be the cheapest, and race to the bottom until they disappear.
The fundamental flaw in the agency model is the incentive structure. You, the agency, are rewarded for inefficiency. A project that takes 100 hours generates more revenue than one that takes 10. A client who needs endless hand-holding is more profitable than one who is self-sufficient. Your business model is directly opposed to your client's best interests.
This creates a culture of ‘billable hours’ over tangible outcomes. It’s a hamster wheel. You hire bright graduates, burn them out tracking their time in 6-minute increments, and then watch them leave to go client-side where they can actually get things done. The entire system is designed to extract value, not create it.
Look at the collapse of a once-great UK retailer like Debenhams. For years, they were a high-street staple. But they were a service layer, a curated collection of other companies' products. They didn't own the stack. When nimble, product-first e-commerce brands like ASOS and Boohoo emerged, owning their own supply chain, logistics, and customer data, Debenhams couldn't compete. They were a middleman in a world that was rapidly disintermediating. Most agencies are the Debenhams of the marketing world.
You are a middleman, renting out the time of your employees. You don’t own the platforms your ads run on (Google, Meta), you don’t own the CRM your client uses (Salesforce, HubSpot), and you don’t own the IP of the strategies you create. When the client leaves, they take everything with them, and you are left with nothing but a line on your P&L.
The transition starts with a psychological shift. You must move from a mindset of 'doing tasks' to 'building systems'. Instead of asking, "How can my team execute this campaign?", you must ask, "How can I build a machine that executes this campaign automatically, repeatedly, and more effectively than any human team could?"
This is precisely how our journey at Creative Marketing Group started. We were running email campaigns for clients, and the process was painfully manual. Copywriting, list segmentation, A/B testing, deployment. It was a conveyor belt of human effort. So, we built a tool to automate it. That tool became Autoemails.
