Building Internal Products Inside a Marketing Agency

The Accidental Product Builder

I didn't set out to build software products. I set out to run a marketing agency. But after a few years of managing enterprise clients at Grow Wild Agency, I kept running into the same problem: the tools we needed didn't exist, and the ones that came close were either overbuilt, underbuilt, or built for someone else's workflow.

So we started building our own.

The first tool was an internal dashboard for managing multi-location client data. Then it was an automation layer for review management. Then a reporting framework that actually showed the metrics our clients cared about. Each tool started as a solution to a specific pain point in our daily work. None of them started as a "product idea."

Why Agencies Are Uniquely Positioned to Build Tools

There's a common narrative in the startup world that you should build a product first and find customers second. The agency model inverts that completely. You have customers first. You're embedded in their operations, facing their problems every day, and building solutions in real time.

That proximity to the customer creates three distinct advantages:

1. You Understand the Problem Deeply

When you're managing marketing for a 21-location enterprise client, you don't need to conduct customer discovery interviews to understand the pain points. You're living them. You know that the operator doesn't want a generic dashboard. They want to know which locations are underperforming, which listings have inconsistencies, and what automated touchpoints will move the needle.

That depth of understanding is almost impossible to replicate from outside. Most product builders spend months trying to achieve the level of customer empathy that agency operators develop naturally through daily work.

2. You Have a Built-In Testing Environment

Every tool we build at Grow Wild gets tested on real clients with real data before we ever consider packaging it more broadly. SiteScore ran as an internal audit tool for months before we formalized it. By the time we had a polished version, we'd already worked through the edge cases, refined the UX based on actual usage, and validated that it delivered measurable results.

3. Revenue Funds Development

Agency revenue pays the bills. Tool development doesn't need to justify itself against a venture capital timeline. We can take the time to build things correctly, iterate based on real usage, and launch when the product is genuinely ready.

What We've Built

Several proprietary tools have emerged from this process:

SiteScore — Our automated website audit tool that generates comprehensive scores across performance, SEO, accessibility, and content quality. We were doing manual site audits for every prospect, and it was taking hours. Now it takes seconds.

AdPulse — Campaign monitoring and anomaly detection. When you're managing ad spend across multiple clients and dozens of campaigns, you need early warning systems. AdPulse watches for budget pacing issues, performance drops, and optimization opportunities.

BrandMap — Multi-location brand consistency tracking. When a client has 21 locations, keeping NAP data consistent across hundreds of directories is a nightmare. BrandMap automates the monitoring and flags inconsistencies before they hurt rankings.

n8n Content Pipeline — An automated content operations system that handles research, drafting, editing, and publishing. This is what allowed us to produce 40+ long-form blog posts without burning out the team.

Each of these started the same way: we hit a pain point, built a solution, and then realized the solution had standalone value.

The Tension: Agency vs. Product

Building tools inside an agency creates real tension. Agency work is service-based — you're selling time and expertise. Product work is leverage-based — you're building something that scales without proportional effort.

Managing this tension is the hardest part. Here's what I've learned:

Don't starve the agency. The agency funds development and provides the feedback loop. If you redirect too many resources to product work, you'll lose the clients that make the tools viable.

Build tools that serve your agency work first. Every tool we've built makes our delivery better. SiteScore makes us faster at prospecting. BrandMap makes our SEO work more efficient. The tools aren't competing with the agency — they're amplifying it.

Ship early, iterate with clients. We don't wait for perfection before deploying a tool internally. We ship the minimum viable version, use it in real engagements, and iterate based on actual usage.

What I'd Tell Other Agency Owners

If you're running an agency and you keep building the same custom solutions for different clients, you're sitting on something. Here's my advice:

1. Document the pattern. When you solve the same problem three times, write down exactly what the common elements are.

1. Build for one client first. Don't try to build something generic from the start. Build for your best client in that vertical, then generalize.

1. Keep the agency and product work close. The agency work informs the tool roadmap, and the tools expand what the agency can offer. That flywheel is the whole point.

The Long Game

The long-term vision is clear: Grow Wild Agency becomes more effective over time because we keep building tools that compound our capabilities. Every engagement teaches us something new about what to build next.

I'm particularly interested in the intersection of AI and the operational tools we build. There's an enormous opportunity to bring intelligent automation to industries that have been underserved by technology — industries where the operators are too busy running their businesses to evaluate and implement complex software.

The agency gives us the customer relationships and domain expertise. The tools give us leverage and efficiency. Together, they form a flywheel that I think is one of the most underrated models in the space.
