Unfortunately this is not possible.

I already have another company but want to create a new one. Can I apply with my new company?

Yes, but you have to liquidate or sell your old company in order to fully focus on your new one.

I have been a long term CEO (or similar) within another company. Can I apply?

No, this program is for entrepreneurs with no pre-existing knowledge about entrepreneurship.

Only if there is a legal document as proof that you have full power over the rights of the idea/prototype/technology.

I am employed but would get (unpaid) vacation for the time of the program. Can I participate?

No, you must leave your employment.

I am a student but finishing my thesis right now (within this semester). Can I participate?

Yes, this is possible, but only if you can prove that there are no open seminars from the curriculum that you have to finish.

I have submitted my application. What are the next steps in the selection process?

By submitting your application you should receive a confirmation email. If you haven’t received a confirmation, please contact us: impactincubator@impacthub.net.

The selection team of Impact Hub Berlin will screen all of the applications. In that phase you might be contacted by Impact Hub Berlin, if any questions should come up.

After screening all applications, the selection team will choose up to 15 teams that will be invited for personal interviews.

In the next step, Impact Hub Berlin will invite teams for the Pitch Day, where our external Advisory Committee composed of experts in the fields of greentech & climate tech, sustainability and business management will finally decide on the admission into the program.

What does the Selection process involve? How will the teams be appointed to Impact Incubator?

In choosing the participants, we’ll take into account the entrepreneurial skills of the team, the potential for scaling and the positive impact of your solution. We’ll also take into consideration how persuasive you are in your pitch / application.

Applications will be assessed on:

  • Social and ecological impact
  • Business model and feasibility
  • Potential to scale
  • Team

The diversity of the team also plays a key role and we aim to have an equal gender split within the cohort.

How many team members can apply?

Our focus is on collaboration – to be selected for the programme you must have a team of at least two founders and up to a maximum of 5 founders.  Please note that every participant has to be a shareholder/co-founder of the company that is to be founded. If you have a great product and are currently seeking co-founders, reach out to our team who may be able to advise or connect you to potential co-founders.

Do I have to attend all events?

Impact Incubator will combine input from experts as well as highly individualized business coaching. As such we will cater to the specific needs of our start-ups and deem them highly relevant. We would expect that you attend all of the events and engage full-time.

Language of the program

The programme will be conducted in English. Please submit your documents and materials in English to attract the broadest range of potential partners and investors.

Who’s behind the Impact Incubator programme?

The Impact Hub Berlin designed the programme, implements all measures and ensures a smooth transition. We belong to a global network focused on building communities for impact at scale. With 100+ communities of almost 24,000 change-driven entrepreneurs in more than 50 countries across five continents, Impact Hub is one of the world’s largest communities and accelerators for positive change. The programme is supported and funded by the European Union (European Social Fund) and the Senate of Berlin. 

How is Impact Incubator affected by Covid?

We take the Covid-19 situation very seriously and follow a safety-first policy. Through the use of technology, we’ve been able to maintain and in certain aspects even strengthen our programme delivery. We carefully align our policies with current developments and will do our best to support you whatever these may be.

Will my costs for travel and accommodation be reimbursed if I travel from outside Germany to Berlin?

All participants of the programme receive a stipend of EUR 2,200 per month, which should cover all costs incurred. In addition – but only for those startups that qualify and show high potential – we may also fund an ‘exposure trip’ to another Impact Hub outside of Germany for the purposes of implementing pilot projects or for traveling to conferences. 

Do I have to pay tax on the scholarship?

Yes, generally the scholarship falls under the “Einkommensteuer” (income tax) and is “Sozialversicherungspflichtig” (subject to social insurance contribution). Whether and how much tax you have to pay for the scholarship depends on your personal situation. Please contact your tax department and/or consultant.

Can I receive other benefits besides the scholarship such as Arbeitslosengeld, Elterngeld, Mutterschaftsgeld, BAföG?

No, your other benefits will be affected by this income.
