Agency, in-house team or hybrid model? An honest comparison
Every growing company reaches this decision: hire an agency, build an in-house marketing team or combine the two. The choice is usually made on the visible monthly cost — and that’s where the mistake lies. Salary is only part of what a team costs; the retainer is only part of what an agency is worth.
The three models
Strengths: deep knowledge of the product and customer, exclusive dedication, fast communication with sales and leadership.
Watch-outs: it’s hard to have specialists in media, SEO, data, CRM and development all at once; hiring, tools, training and replacement costs when someone leaves.
Fits: companies with the volume and budget for a multidisciplinary team, or with marketing closely tied to the product.
Strengths: access to specialists across areas, a method tested with other clients, tools already paid for, speed to get started.
Watch-outs: needs time to learn the business and an internal owner to make decisions and provide information.
Fits: companies that want to professionalize growth without building a whole structure.
Strengths: someone inside owns strategy, brand and alignment with sales; the agency runs the technical fronts with specialists.
Watch-outs: requires clear roles to avoid duplicated work or gaps.
Fits: companies in acceleration that already have marketing leadership, but not a full team.
| Criterion | In-house team | Agency | Hybrid |
|---|---|---|---|
| Business knowledge | High | Grows over time | High |
| Range of specialists | Limited to team size | High | High |
| Speed to start | Slow: hiring and training | Fast | Medium |
| Costs beyond the visible | Payroll taxes, tools, replacement | Time managing the contract | Coordination between the parties |
| Dependency risk | Knowledge concentrated in people | Accounts and data in the agency’s name | Lower, if roles are clear |

What to protect in any model
Whatever you choose, ad accounts, GA4, Search Console, domain and CRM should belong to the company, with access granted to whoever runs them. That’s what guarantees the history and data stay yours if the team changes or the contract ends.
The costs that don’t show up in the first calculation
Comparing one professional’s salary with an agency’s retainer is the most common mistake in this decision. A full in-house growth team spans several specialties — paid media, SEO, content, design, development, data and CRM — and each brings costs beyond salary:
- Payroll taxes and benefits, which significantly raise the cost of each hire;
- Tools for media, SEO, automation, design and analytics, each with its own subscription;
- Hiring and onboarding time, when the cost exists but the result doesn’t yet;
- Training and upskilling on platforms that change all the time;
- Replacement when someone leaves, taking their knowledge with them.
On the agency side, the invisible costs are different: the time of whoever manages the contract, the learning curve on the business and the risk of a partnership that doesn’t deliver. Neither side is free — the question is which cost makes more sense right now.

How the hybrid model works in practice
In the hybrid model, the company keeps in-house whoever knows the business deeply — usually a marketing lead — and the agency runs the fronts that need specialization and tools. The most common split:
| Responsibility | In-house team | Agency |
|---|---|---|
| Strategy and priorities | Decides | Recommends based on data |
| Brand and positioning | Owns and approves | Applies it in campaigns and content |
| Media, SEO and automation | Follows along | Runs and optimizes |
| Data and reports | Uses them to decide | Implements and maintains |
| Alignment with sales | Leads it | Provides the lead readout |
It’s the format Manáry works in most: an owner on the client side, a success manager on ours and the technical fronts run by specialists, with the approvals described in each solution.
Frequently asked questions
Is an agency or an in-house team cheaper?
It depends on scope. To cover several specialties, an agency usually costs less than hiring each professional, once you add taxes and tools. For a single high-volume front, an in-house team can pay off.
Can I switch agencies without losing history?
Yes, as long as the ad accounts, GA4, Search Console, domain and CRM are in your company’s name. It’s something to require from the start of any contract.
How long does an agency take to deliver results?
It depends on the channel and starting point. Paid media usually shows early signs within weeks; SEO takes months. A good agency lays out that horizon before starting.
Does the hybrid model work for a small company?
It works when there’s someone inside with the time and autonomy to decide. Without that person, the agency ends up making business decisions that should be the company’s.
