I spent ten years in the agency world. Built an agency. Sold to clients. Hired people to execute. Watched it work beautifully for quarters at a time, then fall apart. I learned something: the agency model is fundamentally broken for founders.
Not all agencies. Not all relationships. But the model itself—where a vendor creates marketing assets and delivers them to clients—doesn't work for serious business growth. It fails predictably. And better alternatives have emerged.
Why the Agency Model Fails
The alignment problem. An agency makes money when you spend money. They want you to buy bigger packages, more services, more campaigns. You want to spend less for the same results. Aligned? No. This conflict is built into the model.
I watched this from inside. We'd close a client who wanted to do $10K/month in ads. Our margin was 20%. If we could keep them at $10K indefinitely, we made $2K monthly. But if we could get them to $20K, we made $4K. So unconsciously—even well-intentioned people—we optimized for spending, not for results.
The client wanted acquisition cost down. We wanted them to spend more. Eventually they figured it out. They'd leave for a cheaper agency or in-house. We'd close them and get a new client. The model was optimized for churn.
The knowledge problem. An agency accumulates knowledge about how to do things. But that knowledge lives in the agency, not with you. When the agency relationship ends—and they all end—the knowledge walks out the door. Your new agency has to re-learn everything.
You can't scale this. You can't hand it off. You're permanently dependent on external people.
The speed problem. Agencies have process. Intake forms. Project briefs. Review cycles. Revision rounds. Check-ins. I built those processes to maintain quality. But they're slow. Founders who move fast—who experiment daily, who iterate based on data, who make quick decisions—they hate agency timelines.
The leverage problem. When you pay an agency, you're paying for their time. If they need five hours to update your ad copy, you're paying for five hours. If it takes them two hours next month because they've learned the domain, you still pay for two hours. You don't capture efficiency. They do.
This kills compounding. Your cost doesn't decrease. Your results don't compound. You stay on a treadmill.
When Agency Relationships Work (And Why They're Ending)
Agencies work well for specific, bounded projects. You need a logo. You hire a designer. Done. You need a website. You hire a developer. Done. The project has clear scope, clear deliverables, clear end.
But modern business isn't project work. It's ongoing optimization. Your marketing doesn't end. Your content isn't done. Your acquisition strategy needs to evolve weekly based on data.
The founders winning right now aren't doing project-based marketing. They're doing continuous optimization. Agencies are structured for project work. So they're losing.
What Replaces the Agency Model
The winning model for scaling founders has three layers:
Layer 1: In-house strategy and decision making. You own the strategy. You set direction. You make the calls. This doesn't require a huge team. One person who understands your business, your market, your constraints—this person drives strategy. Agency people can advise. But the founder or a small internal team makes decisions.
Layer 2: External specialists for high-leverage work. Some work requires specialized expertise you don't have and won't need long-term. A developer who builds custom infrastructure. A designer who creates a design system. A data analyst who builds your metrics dashboard. You hire them once, they build something that compounds for years.
This isn't paying for ongoing service. It's paying for specific leverage points. After the work is done, the person leaves. The work stays.
Layer 3: Scalable execution systems. Once you've figured out what works (through in-house strategy), you need to execute it at scale. This used to require hiring armies of people. Now you use leverage—tools, templates, automation, offshore labor for routine work.
You might use freelancers for content. You might use a part-time contractor for routine social media. You might use software to automate data processing. The point is that the leverage comes from the system, not from paying more time to specialists.
This is different from an agency because you own the strategy. You own the systems. You own the results. The external people are implementing your strategy, not selling you a solution.
The Economics of the New Model
Let's compare. With an agency, you might spend $10K per month for a small team. Your agency makes $2K. As you grow, you still spend $10K for the same team. The leverage doesn't increase. Eventually, you need more people. So $10K becomes $20K. Your costs scale linearly with complexity.
With the new model: You hire an in-house strategist at $80K/year ($6.7K/month). You pay $5K for specialists on focused projects. You pay $2K for execution tools and freelancers. Total: $13.7K. Expensive, right?
But here's the difference: As you scale, your execution tools scale with you, not your costs. Your strategist gets better at their job, not more expensive. Your specialists build leverage that compounds.
Year two: You're bigger. Your execution scales to 2x volume. Your costs might go to $15K. Not double. Because the leverage is baked in.
With the agency: Year two, you need more service to handle 2x volume. You're paying 2x.
The new model compounds. The agency model doesn't.
The Real Cost of Agencies
There's a hidden cost most founders don't calculate: lost control.
When you depend on an agency for decisions, you lose optionality. You can't pivot fast because they need a new brief. You can't test something new because it's not in their scope. You can't move quickly because process is locked in.
Winners move fast. They test constantly. They iterate based on data. This requires internal control. Agencies remove control.
I learned this the hard way. Built an agency, sold services, got trapped in client relationships that looked good but limited our actual impact. The best outcomes happened when clients brought systems in-house and we just advised. They moved 10x faster. Got 10x better results. But we made way less money.
The Transition
If you're currently working with agencies, this doesn't mean "fire them tomorrow." It means strategically shift:
First, hire someone in-house who owns strategy. This person is your stakeholder with the agency. They understand your business deeply. They can evaluate agency work critically. They start learning what actually drives your metrics.
Second, bring the critical path in-house. The work that directly impacts your core metrics? That needs to live with you. Everything else is supporting work that can stay external.
Third, end projects, not relationships. Shift from "let's hire this agency for ongoing management" to "let's hire them to build this specific thing that we'll then own." When the project is done, the relationship ends. You own the results.
Fourth, measure ruthlessly. Make every vendor prove ROI. If an agency isn't moving your metrics, cut them. The new model is no longer "we're nice relationships," it's "prove impact or leave."
The Reality for Agencies
This isn't a rant against agencies. Some are excellent. But the model is broken. The best agencies are already shifting—away from retainers, toward project work and advisory. Away from "we manage this for you" toward "we show you how to do this."
The agencies that survive will be the ones that embrace this shift. They'll be specialized. They'll do specific, high-leverage work. They'll build leverage into their work so clients own the results. But they'll be smaller, because the client does more themselves.
For founders: the future isn't vendor relationships that last forever. It's strategic clarity, in-house decision-making, and external specialists on focused projects. The future is control.
