UnternehmerTUM in Munich calls its programme an incubator. It runs for 10 to 12 weeks, starts twice a year in March and September, and takes no equity (UnternehmerTUM, 2026). By the most cited academic definition, a fixed-term programme that admits founders in cohorts is an accelerator (Cohen and Hochberg, 2014). Nothing is wrong with the Munich label. It simply shows how little the label tells you.
For programme managers, those differences matter when explaining the offer to founders, sponsors or university leadership. A clear account of the support, timetable and expected outcomes is more useful than the programme name alone.
This guide compares the three models and the events each typically runs. After the definitions, we look at who meets whom, how often they meet and what the organising team needs to prepare. The calendar is a useful way to see how the programme works in practice.
What is the difference between an incubator, an accelerator and a venture studio?
The three models differ in when they start working with a company, how long they stay and who brings the idea. In short:
- An incubator supports early ventures over an open period, often with space, advice and a community. Companies stay as long as they need, often one to five years, and admission is less selective (Cohen and Hochberg, 2014).
- An accelerator is “a fixed-term, cohort-based program, including mentorship and educational components, that culminates in a public pitch event or demo-day” (Cohen and Hochberg, 2014). It usually invests a small amount for equity.
- A venture studio creates startups itself, acting as founder or co-founder, and runs several new ventures in parallel through a standard process (Viglialoro et al., Technovation, 2026). In German-speaking markets, the same model is often called a company builder.
The table compares the three from the organiser’s point of view.
| Incubator | Accelerator | Venture studio | |
|---|---|---|---|
| Who brings the idea | The founders | The founders | The studio, then recruits founders |
| When it starts | Idea or very early stage | Early product or first traction | Before the company exists |
| Length | Open, often 1 to 5 years | Fixed, typically 3 months | Until the venture can stand alone |
| Selection | Rolling, often less selective | Competitive, once per cohort | The studio picks ideas and founders |
| Money | Rent or public funding, rarely equity | Seed money for equity | Studio capital and team, larger stake |
| Typical events | Workshops, office hours, community evenings | Selection day, mentor sprint, demo day | Founder recruitment, validation sprints, investor days |

The money row is where most founder guides stop. Y Combinator, for example, invests 500,000 US dollars: 125,000 for 7 per cent of the company and 375,000 on an uncapped SAFE (Y Combinator, 2026). Techstars has offered 220,000 US dollars since April 2025, with a minimum stake of 5 per cent (Techstars, 2025). These are the providers’ own terms and change regularly. For you as an organiser, the last row of the table matters more.
Why the calendar says more than the name
The last row matters because the events are not decoration around the programme. They are the programme. A study of early US accelerators found that some, but not all, of them substantially accelerated the development of their startups (Hallen, Cohen and Bingham, Organization Science, 2020). The authors traced the effect to what they called “broad, intensive, and paced consultation”: founders meet many advisers, often, and in a planned rhythm.
Read that phrase as an organiser and it describes a calendar. Broad means many different mentors and investors. Intensive means many meetings in a short time. Paced means the meetings follow a sequence with deadlines. A programme that calls itself an accelerator but offers one workshop a month and an open demo evening does not deliver this. A programme that calls itself an incubator and runs a twelve week cohort with weekly mentor slots probably does.
So when your sponsor asks what the programme is, show them the calendar. The rhythm is the model.
The incubator calendar: a steady rhythm with an open door
Incubators usually offer an ongoing programme: teams join at different points, stay for months or years and draw on support as they need it. Their calendars therefore tend to follow a recurring rhythm of workshops, advice sessions and community events.
Typical formats are weekly or monthly workshops on topics such as funding or first customers, expert office hours that teams book when a question comes up, peer sessions and community evenings. Many incubators also host a demo day, but often as a community event for several programmes rather than as the end of one cohort.
The organiser’s problem here is distribution, not intensity. Picture an incubator with forty teams and twelve experts. The two experts everyone has heard of are fully booked within a day, while the patent lawyer waits with an empty calendar. Our guide to mentor office hours shows how to cap and spread that demand so the quieter experts get the teams that need them.
The second problem is return visits. An open calendar only works if teams come back. Regular participation helps turn individual events into a lasting support network. If your incubator also serves founders who are not enrolled, the formats overlap with community building; our article on ecosystem builder events covers the open formats between the big conferences.
The accelerator calendar: a compressed sequence with fixed milestones
Where the incubator repeats, the accelerator builds towards one date. Y Combinator describes its batch as a three month programme that takes place in person in San Francisco (Y Combinator, 2026). Techstars calls its accelerator a three month, mentorship driven programme (Techstars, 2025). Within those weeks, the events follow a fixed order, and each one depends on the one before.
Accelerator calendar
Six events from application to follow-up
- Before week 1 Selection day Shortlisted teams pitch and are interviewed. The panel decides who joins the cohort.
- Weeks 1 to 3 Mentor sprint Many short meetings with many mentors, ending with one or two lead mentors per team.
- Weekly Office hours and peer sessions Fixed slots with partners and mentors, plus a regular round in which teams report progress.
- Weeks 8 to 11 Investor preparation Pitch rehearsals, feedback rounds and the first one-to-one introductions to investors.
- Final week Demo day Every team pitches to a curated audience of investors, partners and press.
- After Investor follow-up Pre-booked meetings and tracked next steps in the weeks after the stage.
The first and the last step get the most attention, and both deserve it. How to run a fair selection day with parallel panels and calibrated scores is the subject of our guide to the accelerator selection day. What the closing event should achieve, and why the follow-up matters more than the stage, we explain in what a demo day is.
The mentor sprint in between is the step programmes underestimate. Techstars made the format famous as Mentor Madness: at the start of a 2016 corporate programme, startups spent three weeks meeting a dozen mentors for 20 minutes each, in four hour stretches, before each team was matched with one lead mentor (Target, 2016). Ten teams and thirty mentors produce hundreds of slots. At that scale, changes and scheduling conflicts need a reliable process.
Funding outcomes provide another reason to look closely at how the programme supports investor relationships.
What accelerators change
Funding one year after applying
Participants raised more than twice as much new funding as rejected applicants, and almost three times as much equity. The averages hide a wide spread between programmes, and a ten year review of the same data adds the explanation. Founders who did not credit the programme for their success most often cited a lack of meaningful connections with investors (Porticus, 2024). For you, that turns investor preparation and demo day follow-up into the part of the calendar your sponsor will judge.
The venture studio calendar: events before the company exists
Accelerators and incubators wait for founders to apply. A venture studio starts earlier. A case study of 14 Italian studios found that they generate business ideas themselves and then build and validate them together with outside entrepreneurs (Moiana, Ghezzi and Rangone, 2024). The studio, not the founder, is where the idea starts.
That reverses the purpose of the events. The studio’s calendar is less about advising existing teams and more about assembling new ones. In practice, three formats tend to appear:
- Founder recruitment: information evenings, founder or entrepreneur in residence programmes and interview days, at which the studio meets people who could lead one of its ideas.
- Validation sprints: short, intensive rounds of interviews with potential customers, often with corporate partners, before the studio decides to spin out a company.
- Investor days: closed sessions at which the studio presents several ventures at once to the investors who might fund them after the studio phase.
Founder recruitment is a matching problem. The studio has an idea that needs a technical lead with sector experience, and twenty applicants who are interesting for different reasons. Treat the evening as the first of several meetings, and match on role and commitment before anyone arrives. Our guide to co-founder matching events describes the formats that work. The studio is simply one side of the match.
One programme, several calendars
The three models rarely appear in pure form. A university may run an open incubator, a twelve week accelerator track and a spin-off programme that works much like a studio. A corporate programme may combine an accelerator cohort with a venture clienting track in which business units buy pilots rather than shares. Techstars itself now runs a 10 week, part-time and mostly virtual pre-accelerator without equity, for founders who have raised less than 400,000 US dollars (Techstars, 2026).
Mixing models is fine. Mixing their calendars is where it goes wrong. The incubator team that joins the accelerator’s mentor sprint takes slots from the cohort. The investor who comes to the open demo evening expecting an accelerator demo day leaves with the wrong impression of both. Keep one calendar per model, decide which events are shared, and tell each group which of them it is invited to.
That is also the answer for your dean or sponsor. Show them which events serve which group, and what each event is supposed to produce. A label cannot do that.
Converve schedules the meetings inside these calendars with a rule-based meeting matrix that your team controls. You define the slots and which groups may meet: jurors and shortlisted startups on selection day, mentors and teams in the mentor sprint, investors and founders at demo day. Each person gets a capacity limit, participants request and confirm meetings within your rules, and every meeting is stored as a scheduled appointment, so you can show afterwards who met whom. You can see how this works for startup and investor events.
Frequently Asked Questions
What is the difference between an incubator and an accelerator?
An incubator supports early ventures over an open period, often one to five years, with space, advice and a community, and admits teams on a rolling basis. An accelerator runs a fixed-term programme, typically three months, for a selected cohort, usually invests seed money for equity and ends with a demo day (Cohen and Hochberg, 2014).
Is Y Combinator an incubator or an accelerator?
Y Combinator is an accelerator. It admits companies in batches, runs a three month programme in person in San Francisco, invests 500,000 US dollars on standard terms and ends each batch with a demo day (Y Combinator, 2026). People sometimes call it an incubator, but its fixed term and cohort model match the accelerator definition.
What is a venture studio?
A venture studio, also called a startup studio or company builder, creates startups itself. It develops the idea, provides an operating team and capital, recruits founders to lead each venture and holds a larger stake than an accelerator. Research describes studios as organisations that act as founders or co-founders and build several ventures in parallel (Viglialoro et al., Technovation, 2026).
What is the difference between incubation and acceleration?
Incubation protects a young venture while it develops, without a fixed end date. Acceleration speeds up a venture’s contact with the market through a short, intensive and scheduled programme. One study traced the effect of successful accelerators to “broad, intensive, and paced consultation” with many advisers (Hallen, Cohen and Bingham, Organization Science, 2020).
Do accelerators take equity?
Most do, but not all. Y Combinator takes 7 per cent for 125,000 US dollars plus a further uncapped SAFE, and Techstars takes at least 5 per cent as part of a 220,000 dollar investment (provider terms, 2025 and 2026). Many university and public programmes take no equity at all, such as the UnternehmerTUM incubator in Munich.
Which events does an accelerator run?
A typical accelerator runs a selection day before the cohort starts, a mentor sprint in the first weeks, weekly office hours and peer sessions, investor preparation in the final weeks, a demo day at the end and structured investor follow-up afterwards. Each event depends on the one before, which is why accelerators plan them as one sequence.
Making your programme clear through its calendar
Incubators, accelerators and venture studios offer different kinds of support. An incubator provides ongoing guidance, an accelerator brings a cohort through a defined programme, and a studio helps build new companies. Their activities can overlap, so explain your own model through its services, milestones and event calendar.
So plan your programme from the events backwards. Decide who must meet whom, when and with what result, and the model follows. If your next date is the end of a cohort, our demo day playbook covers the twelve weeks before it.
