Every growing company hits this question at almost the exact same spot
It happens somewhere between $3M and $8M in revenue, close enough to a pattern that you could set a watch by it. Marketing has outgrown whoever's been handling it on the side, usually a founder, an ops person, or an agency that was hired for one campaign and quietly became the whole department. Leadership starts asking the question in a conference room: do we build a real internal team, or do we go find a real agency partner. Both options feel like a leap, and most companies frame it as a permanent, either-or decision when it isn't one.
The real math on building in-house
A functional four-person internal marketing team, someone owning strategy, someone on content, someone on paid and analytics, someone on design or production, runs $300,000 to $450,000 a year once you add salary, benefits, software subscriptions, and basic equipment. And that number doesn't include video production or web development, both of which usually get bolted on as separate line items or separate hires.
The cost that doesn't show up on the org chart is your own time. Hiring in-house makes you a manager, whether you meant to sign up for that or not. Reviewing work, giving feedback, running one-on-ones, handling a bad hire or a departure, that's real hours every week that didn't exist before. If your own time is worth anything close to what you bill or generate elsewhere in the business, that management overhead is a genuine cost, even if it never appears on an invoice.
The real math on an agency
For a company in the $3M to $10M range, a full-service agency engagement, strategy, content, paid media management, and reporting, typically runs $3,000 to $8,000 a month, with ad spend billed separately straight to the platforms. That buys access to a full bench of specialists you'd otherwise have to hire one at a time, without the fixed overhead of salaries and benefits sitting on your books whether business is up or down that quarter.
The tradeoff is real too. An agency isn't in the building. It doesn't absorb your culture by osmosis, and it works best when someone internal owns the relationship, sets priorities, and keeps the agency pointed at what actually matters instead of whatever's loudest that week. An agency without an internal owner tends to drift toward busywork that's easy to report on rather than the work that actually moves revenue.
| Revenue range | What tends to work |
|---|---|
| Under $2M | Agency for everything, no internal hire yet |
| $2M to $5M | Hybrid: one internal strategist, agency for execution |
| $5M to $15M | Small in-house core, agency for specialized work |
| $15M+ | In-house scales further, with stable process and budget |
The honest answer is hybrid, and here's where the line actually sits
Almost every credible framework on this question lands in the same place once you strip out the sales pitch: most companies between $1M and $25M in revenue do best with one senior internal person who owns strategy, brand, and vendor management, paired with an agency or a set of specialists for the execution that requires depth, video production, paid media, SEO and AI search work, content at volume. That internal person is the throughline. The agency is the bench.
Where this shifts is capacity and specialization. A company doing $500,000 in revenue almost never needs a hire yet, an agency or a done-for-you setup covers it. Somewhere around $2M to $5M, the volume and complexity usually justify one strong internal strategist, with an agency still doing the heavy execution. Past roughly $15M, the math starts to favor bringing more in-house, because you can finally afford senior talent and still have budget left for real execution capacity.
The question almost nobody asks first
Most of this decision gets framed around a single number: what percentage of revenue should go to marketing. That's the wrong starting point. The better question is what specific outcome you're trying to buy, qualified leads, brand awareness in a category, a faster sales cycle, and what it actually costs to produce that outcome given your real conversion rates and deal economics. A company with a six-figure average deal size and a twelve-month sales cycle should be spending very differently than one selling a $500 product with a same-week close, even at identical revenue.
Every marketing dollar, regardless of company size, ultimately lands in one of three buckets: people, whether internal headcount or agency fees, technology, the martech stack running underneath everything, and media, the paid spend and content distribution actually reaching buyers. Getting the sequencing right across those three matters more than hitting some industry-average percentage of revenue.
What this actually looks like in practice
We've watched companies like RGC Marine and Stride Aquatics work through exactly this decision as they grew past the point where one person could quietly own marketing on the side. In both cases, the fix wasn't picking a side. It was getting clear on which parts of the work needed a permanent internal owner, brand voice, vendor relationships, overall strategy, and which parts genuinely benefited from an outside team that does this full-time across multiple industries and has already made the expensive mistakes elsewhere.
That's the same principle underneath our own model. We're not trying to replace an internal marketing hire, and we're not trying to be your only marketing function forever. We're the specialized execution arm, the video production, the demand research, the content built at real depth, that most companies in this revenue range can't yet justify building and staffing internally, and honestly, in most cases, shouldn't.
