I run a HubSpot agency. You have every right to expect a post with this title, written by an agency owner, to conclude that you should hire the agency.
This one won't.
About half the companies I walk through this framework end up deciding that an in-house hire is the right call for where they are. That's fine. The wrong call costs people money and wastes a year of their lives, and I'd rather hand you the honest framework than the convenient one.
So here's what's actually at stake, and how to think through it without the pressure of a vendor on the other end of a phone call.
Someone in leadership decides the company needs to take HubSpot more seriously. Marketing is lagging, reporting is thin, automation never really got built out, and the person currently "managing HubSpot" is doing it as 15% of a job that's actually three other things.
A HubSpot admin job description gets drafted. Salary gets benchmarked. Someone looks up a few agency retainers, does quick math against that salary, and reaches a conclusion in the next 48 hours.
Six months in, whichever path got chosen isn't working, and nobody can quite say why.
The reason it isn't working is almost never the person or the agency. It's that the decision was made against the wrong math. Salary against retainer is a comparison you can do in a spreadsheet. It's also a comparison that gets most of this decision wrong.
Most companies don't walk into this decision asking "should we hire in-house or work with an agency?" They walk in asking more basic questions.
"We have someone already. Can they just do this?"
Maybe your marketing coordinator has been running HubSpot as 20% of their job. They know the company, the products, the customers. They're not new. But they're not a HubSpot specialist either, and the platform has grown faster than their familiarity with it. The real question is whether the gap between where they are and where you need them to be is a training gap, a time gap, or a skill gap. Training gaps close. Time gaps mean you need more capacity, whether internal or external. Skill gaps require a different kind of talent than the person sitting in the chair.
"We're bringing HubSpot on for the first time. Do we need help setting it up and running it?"
HubSpot sells itself on ease of use. It is, broadly, easier than the enterprise alternatives. But "easier than Salesforce" and "easy for your team to implement well while also doing their regular jobs" are different claims. A HubSpot implementation done poorly sets you back six months to a year, because you end up rebuilding things that were configured on bad assumptions. The question isn't whether your team can figure it out. It's whether figuring it out is the best use of their time during a period when you actually need them doing their actual jobs.
"How much staff does HubSpot actually require?"
This is the question that most deserves an honest answer: it depends on how much of HubSpot you're using. A company using HubSpot for marketing email and a basic CRM needs less than a company using Marketing Hub Pro, Sales Hub Pro, Service Hub, Content Hub, Breeze AI, and custom integrations. The scope of your HubSpot usage drives the staffing question, not the platform's existence.
All three of those questions eventually land you at the same decision point: how do I resource this well? The three paths below are how that decision usually gets resolved.
In-house hire. Makes sense when HubSpot work is predictable, your processes are stable, the workload fills a full-time role, and you need someone who lives inside your business context every day. A good in-house admin builds institutional knowledge that compounds over years.
Agency or partner. Makes sense when you need expertise across multiple specialties (content, automation, reporting, integrations, custom development) that no single hire can deliver, or when your workload is project-shaped rather than steady-state, or when you're in a transition period where flexible capacity matters more than internal ownership.
Hybrid. Makes sense when the workload supports a full-time person but the skill mix required exceeds what one person can cover. The in-house role handles day-to-day ownership and institutional continuity; the external partner brings specialized depth on whatever's beyond the individual's scope.
Each of these paths works. Each of these paths fails. What determines success isn't which one you pick — it's whether the path you pick matches the actual shape of the work you need done.
Honest inventory: if most of these describe your situation, you're probably looking at an in-house hire.
Your HubSpot workload is steady and predictable. Not project-spiky, not seasonal, not "we'll need a lot of help during the relaunch and then less after." Every week looks roughly like every other week, and the volume of work genuinely fills 40 hours.
Your processes are stable. The marketing playbook isn't changing quarter to quarter. The sales motion has been roughly the same for two years. The reason HubSpot needs more attention isn't that everything is in flux — it's that execution on a settled playbook has gaps.
The work is primarily day-to-day operational, not strategic or specialized. Daily dashboard maintenance, list management, workflow tweaks, sales enablement support, data hygiene. The kind of work that rewards someone knowing your specific portal, your specific data model, your specific sales reps by name.
You have the internal bandwidth to manage a hire well. Hiring isn't free. Onboarding, mentoring, performance management, and career development are real costs that fall on whoever that person reports to. If your marketing leader is already at capacity, adding a direct report is adding work, not reducing it.
You're committed to keeping this person for at least two to three years. HubSpot admins are actively recruited. If your comp philosophy or culture makes retention a challenge, the math on in-house gets worse quickly. A hire who leaves at 18 months has usually cost more than they returned.
If most of those describe you, hire someone. Don't let anyone — including me — talk you out of it.
External help doesn't have to mean an agency. HubSpot's own onboarding services are often the right call for straightforward first-time deployments. If most of the following describe you, outside expertise of some form — agency, partner, or HubSpot's own team — is probably the right direction.
You need multiple specialties at once. Content, automation, reporting infrastructure, integrations, Content Hub development, Breeze AI implementation, custom modules. These are genuinely different skill sets. A single hire who's competent in all of them costs well into six figures and is very hard to find. An agency brings the specialties already assembled.
Your workload is uneven. Some months are heavy, some are light. Project-shaped work — migrations, relaunches, campaign builds, integration projects — doesn't fit a full-time hire well. You end up either overpaying during light periods or burning out the person during heavy ones.
You're in a transition period. New leadership, new product direction, pending pivot, new market expansion. When the business itself is moving, what you need from HubSpot is moving too. A hire who's been optimized for the current state may need to rebuild against the next state. Agency work during transitions is usually more flexible than internal restructuring.
Your internal marketing leader needs strategic capacity more than execution capacity. If the person running marketing is spending their time managing a HubSpot admin instead of thinking about go-to-market, you've inverted the value of the role. Sometimes an agency keeps your marketing leader operating at the altitude they were hired for.
You've done in-house before and it didn't stick. This is the signal most companies miss. If you've hired two HubSpot admins in three years and neither lasted, the failure isn't with the people. It's with the fit between the job as defined and what the business actually needs. An agency can often diagnose that gap and help you rebuild the role correctly — or conclude that there isn't a full-time role to be had.
If three or four of those describe you, you're not trying to avoid an agency — you're trying to decide which kind of outside help fits. Different question, different answer.
Most companies compare salary to retainer and stop there. Both numbers are incomplete.
What the in-house number actually includes:
What the agency number actually includes:
An $8,000 per month retainer is $96,000 per year.
The comparison isn't $90,000 salary vs. $96,000 retainer. It's $115,000 to $135,000 fully loaded in-house vs. $96,000 total agency cost.
That's before you count the value of what each path delivers differently. An agency brings cross-client pattern recognition you'll never get from a single hire. A hire brings institutional depth no agency can match. Neither is strictly better. They're different investments.
HubSpot expertise is one of the most actively recruited skill sets in B2B marketing. Demand significantly outpaces supply, and the gap is growing as HubSpot's AI capabilities make platform knowledge more valuable.
Which means the person you hire, train, and build your marketing operation around is walking around with a skill set other companies will pay a premium for.
This isn't theoretical. It plays out in the market every month. Short tenures are common in HubSpot admin roles — someone comes in green, gets trained up enough to be genuinely useful, and gets recruited away before they've built real depth. And whoever's leaving takes institutional knowledge with them that nobody documented — the custom workflow logic, the data model decisions, the integration quirks, the reasons certain things are set up the way they are.
The question isn't whether this will happen. For a large fraction of admin hires, it will. The question is whether you've planned for it.
Companies that hire in-house successfully usually do three things:
If you can commit to all three of those, the retention risk is manageable. If you can't, it's significant.
After all of the above, the real pivot is a question nobody asks early enough:
Is the work I need done actually one job, or has the job description quietly become three?
Content creation. Marketing automation. AI implementation. CRM management. Strategic thinking. Reporting infrastructure. Custom development.
Those are seven distinct skill sets. A capable HubSpot admin can do some of them well. No single hire can do all of them well.
If the scope you've written for the role requires three of those skill sets, a good hire is a reasonable bet. If it requires five, you're probably looking at a role no single person will succeed in. You're either going to hire someone who disappoints you or overpay for a unicorn.
That's the moment hybrid or agency becomes the right answer — not because agencies are better, but because the scope has exceeded what a single hire can deliver.
The companies I watch get this wrong aren't the ones who hire the wrong person. They're the ones who wrote a job description that couldn't be filled by any person.
If you're mid-decision on this, the most useful thing you can do is spend fifteen minutes pressure-testing your thinking against a structured framework.
I built a diagnostic called the HubSpot Staffing Reality Check. It walks through the questions above and generates a personalized analysis based on your specific situation. Sometimes it recommends in-house. Sometimes agency. Sometimes hybrid. I built it that way on purpose. Getting the right answer matters more to both of us than getting the convenient one.
It's free, and no email required to see your results. The full analysis lands in your inbox if you want it.

Whichever path ends up being right for you, the important thing is that you made the call against the real math, not against the easy one.
