Is an agency more expensive than a freelancer?

Per day, often yes. Over a complete project the gap narrows: the agency covers design, development, AI and going to production without you having to coordinate several people.

Can you start with an agency and then bring it in-house?

Yes, and it is a good path if planned from the start: code in your repository, documentation, accounts in your name, then a handover period with the person hired.

Which questions should you ask an AI provider?

Which projects are in production, how answers are verified, what the monthly running cost is, who owns the code and the accounts, and what happens if the model used is replaced.

AI agency, freelancer or in‑house team: how to choose

By the Banzai Labs teamUpdated on November 11, 20262 min read

Three options, three needs

	Freelancer	Agency	In-house team
Best for	A specific component	A complete product	A permanent need
Time to start	Short	Short	Long (hiring)
Range of skills	One or two	Design, dev, AI, hosting	Depends on hires
Continuity	Depends on one person	Carried by a team	Strong
Coordination	Yours	Included	Yours
Commitment	Low	Medium	High

When to choose a freelancer

The need is bounded: a connector, an automation, an audit.
You have someone in-house to scope and accept the work.
The project can wait if the person is unavailable.

The risk is dependence. Ask for documented code, in your repository, and access in your name.

When to choose an agency

The project needs several disciplines: design, web, mobile, AI, going to production.
You want one contact and one result, not a team to manage.
There is a date to meet.
You have no technical team.

Check that the agency builds the work itself. Some resell subcontractors’ work, others only consult. Our criteria are in AI digital agency: how to choose one.

When to hire

AI is at the core of your product, not one more tool.
The work is continuous, over several years.
You have what it takes to manage and retain these profiles.

Hiring too early is a common mistake: you recruit before knowing which use case pays off. A first project run with a provider gives the answer and sharpens the profile to look for.

The costs people forget

FreelancerYour coordination time, and the risk of interruption.
AgencyChanges outside the scope, to frame from the quote onwards.
In-houseRecruitment, payroll costs, management, tools, and the months before the first delivery.

In all three cases, the monthly running cost of models comes on top. See How much an AI project costs.

What must stay with you, whatever you choose

The code repository.
The accounts: domain, hosting, model providers, stores.
The data and the test sets.
The documentation of what each agent does.

A provider who keeps these makes you captive.

The mixed solution

It is often the best one. An agency builds and ships the first version. Someone on your side becomes responsible for it and learns along the way. Maintenance is then shared according to workload.

Local or remote

For a software project, distance changes nothing in the result if the method is in place. See the nomad agency.
