Startup studio vs incubator vs agency: what each offers and what it costs you in equity
Three models that look alike from a distance and ask for very different things, mostly in equity.
What is the difference between a startup studio, an incubator and an agency?
The difference is who owns the idea, who makes decisions and what you pay with: shares, cash or both. The table summarises it before we look at each model.
| Startup studio | Incubator or accelerator | Development agency | |
|---|---|---|---|
| Whose idea | Often the studio's | The founder's | The founder's |
| What it provides | Shared team, capital, playbook | Mentoring, network, space, sometimes capital | Product design and engineering |
| What it takes | A significant equity stake | Equity, fees or both, depending on the programme | Cash, per quote |
| Who decides | Shared with the studio | The founder, with advice | The founder |
| Time frame | Years | Months, per programme | The project, plus any maintenance |
| Best for | Founders who want to co-found with an institution | Founders with a team and early traction | Founders who know what to build and have budget |
What is a startup studio, or venture builder?
A startup studio, also called a venture studio or venture builder, is an organisation that launches companies in series, often from its own ideas, giving each one a shared team across product, engineering, design and marketing plus early capital. In return the studio becomes one of the main shareholders.
It is the closest thing to an institutional co-founder. You get experienced people from day one and a tested process, sometimes an idea that is already validated. You also give up a substantial share of the company and some say over decisions. There is no reliable public benchmark for studio terms, because each studio sets its own: get the offer in writing and compare it with what you would give a technical co-founder.
How do incubators and accelerators differ?
Incubators support very early companies over a longer period, typically with space, services and mentoring; accelerators run short, intensive programmes for startups that are already moving, often ending with an investor demo day. Techstars, for instance, describes its accelerators as three months of intensive, mentorship-driven support.

YC is a useful reference point because its terms are public and identical for every company, and it states that it charges no fees to take part. Other programmes work differently, and terms can change between cohorts, so always read the current official terms of the programme you are considering.
If you are a foreign founder setting up in Italy, you will also meet the certified incubator (incubatore certificato), a status defined in Italian law. According to the Ministry of Enterprises, it is an Italian-resident company that supports innovative startups and must show suitable facilities, experienced management, regular ties with universities and research centres, and a track record; it self-certifies in a special section of the Business Register and reconfirms every year. Certification describes the organisation, not the deal it offers you.
What does a development agency do, and not do?
An agency designs and builds the product you ask for, ships it and often maintains it, for a fee. It does not give you capital, does not necessarily introduce you to investors and does not share the business risk: product and market decisions stay with you. In exchange it takes no equity, so the cap table stays with you and your co-founders.
With an agency the sensitive issue is not equity but control: code, repository and accounts must belong to your company. If that is your route, see how to choose a software development company and how it compares in agency vs freelancer vs in-house.
How much equity does each model take?
An agency takes none, an accelerator usually a smaller stake, a studio the largest, because it co-founds the company. Every point given away early compounds through later rounds: Carta reported in 2026 that by the seed round the median founding team owns 55.8% of the company, and by Series A just 36.2%.
Four questions to choose
Do you already have a validated idea and a team?
If yes, an accelerator or an agency fits better than a studio, which makes most sense when the team is what you lack.
What is really missing: people, capital or network?
People and capital together: a studio. Network and method: an incubator or accelerator. Build capacity: an agency.
How much control do you want to keep?
The more structure you receive, the more decisions you share. Put it in writing before signing.
Who will own the code and the accounts?
Under every model the answer should be the company. Check the contract, as explained in who owns the code in a software contract.
What should you ask before joining a studio or programme?
Ask everything about equity, decisions and exit, in writing, before you sign. This is our minimum list:
- What stake do you take, through which instrument and at what point?
- What do I get in return, concretely: people, hours, capital, services?
- Who decides on product, hiring and investors, and how are disagreements resolved?
- Is your stake subject to vesting or milestones, like the founders'?
- Can I speak to founders of companies that have been through your programme?
- What happens if either of us wants to end the relationship?
Can you combine these models?
Yes, and many startups do. You might join an accelerator and have an agency build the product, or validate with a visual builder before moving to custom code, as discussed in no-code vs custom development. What matters is knowing who does what and who owns what at each stage.
Frequently asked questions
Is a venture builder the same as a startup studio?
In practice, yes: both describe organisations that create startups in series with their own team and capital. The differences lie in each studio's model, not in the label.
Do all accelerators take equity?
No. Some take equity, some charge fees, some do both. Read the current terms of each programme rather than assuming.
Accelerator or agency to build my MVP?
They do different jobs. An accelerator helps with method, network and sometimes capital but usually does not build the product; an agency builds it but does not invest. Many startups use both at different moments.
Will an agency work for equity?
Some do, wholly or partly. The agency then becomes a shareholder and the relationship changes, so take legal and tax advice and agree what happens if the collaboration ends.
Should I join a startup studio if I already have an idea?
Possibly, if the studio accepts external founders and brings skills you cannot hire. Weigh the equity it asks against the cost and time of building a founding team yourself.
