Most companies compare these four models on price and timeline, which is the one comparison that tells you nothing. They are built for different jobs. A consultancy sells an answer, an agency sells delivery, an in-house team sells continuity, and a studio takes a position in what gets built.
What are you actually choosing between?
Three questions separate the four models cleanly.
Who carries the risk if the thing does not work? Who owns what gets built when the engagement ends? And does the arrangement end at a document, at a launch, or at an operating asset?
What is a consultancy good at?
Framing a decision you cannot frame internally. Independent analysis, a defensible recommendation, and a document that survives a board meeting.
The limit is the handover. The recommendation lands with the people who were already too busy to make it, and the risk stays entirely with you.
What is an agency good at?
Building the thing that has already been specified. Clear scope, known output, predictable cost.
The limit is that an agency is paid to deliver the brief rather than to question it. If the specification embeds the wrong assumption, you get a well-built version of the wrong thing.
When does an in-house team make sense?
When the work is continuous, close to the core, and needs the context your people already carry. Nothing beats it for maintaining something that matters every day.
The limit is the starting cost. Hiring a product, design and engineering group takes months before the first decision gets made, and the first attempt is the most expensive one to get wrong.
What does a venture studio do differently?
It validates before it builds, builds with your experts rather than around them, and stays in for the outcome. At Mayfly that includes investing in what we build, which changes the conversation about what is worth building at all.
The limit is fit. A studio is the wrong choice for a defined piece of delivery work with a fixed brief. Use an agency for that.
How do the four compare?
| Consultancy | Agency | In-house | Venture studio | |
|---|---|---|---|---|
| Sells | An answer | Delivery of a brief | Continuity | An operating asset |
| Ends at | A document | A launch | Never | A business that runs |
| Risk sits with | You | You | You | Shared |
| Best when | The decision is unclear | The scope is clear | The work is continuous | The constraint is structural |
| Watch for | No handover | Unquestioned brief | Slow start | Wrong fit for small scopes |
Which one fits your constraint?
If you cannot name the problem, buy analysis. If you can name it and specify the answer, buy delivery. If it is permanent and central, hire.
If the constraint is structural, meaning your growth depends on hiring or on judgement held by a few people, none of the first three removes it on their own. That is the case a studio is built for.

When judgement lives in five heads
In most expertise-led companies the hardest decisions queue behind two or three people. What that costs, how to see it early, and how to move it.
