Proof of Concept

TEST YOUR PRODUCT IN FRONT OF MORE THAN 1000 CUSTOMERS

Ten start-up teams will launch their products live at the summit. They will present their ideas to over 1,000 potential customers with their pitches. This will give them initial feedback from the market and enable them to take the next step with their start-ups.

You too can launch your start-up live at the Entrepreneurship Summit, pitch your product and receive valuable feedback.

Please note: The Proof of Concept will take place offline and in German, so we can only consider submissions that can participate in person and German language.

The application period is now closed.

Good entrepreneurial designs always involve a lot of work. It often takes years to develop a business concept.

At some point, the time comes when you have to test the basic assumptions of your business model. At the Entrepreneurship Summit 2025, you have the opportunity to carry out the first market test for your entrepreneurial design - your business idea - under very real conditions with over 1000 Summit participants as part of the Proof of Concept format.

The Proof of Concept will take place during the Entrepreneurship Summit weekend from 11-12 October 2025. The aim is to receive as many binding orders as possible within this time and generate the highest possible turnover.

Become a fairHANDLER

Do you know that feeling during negotiations when you think: There could have been so much more to gain?

Your counterpart uses tricks, puts pressure on you – and in the end, you've paid too much

or sold yourself short.

This is exactly where fairHANDLER comes in.

Our mission is to support solopreneurs, founders and digital nomads in conducting negotiations successfully and fairly.

Fair in the outcome. Fair for you. Fair for your negotiating partner. And fair to the environment and resources. Because if you want to build good long-term relationships, you don't need a battle strategy – you need clarity, attitude and practice. That's why we're creating a training space for fair negotiators:

At the fairHANDLER Campus, you'll combine structured know-how with practical experience and personal growth.

Our approach is unique:

- The Harvard principle for objective, solution-focused negotiation

- Improvisation techniques from the theatre for spontaneity, responsiveness and authentic behaviour

- NLP-based self-work to remove blockages, develop attitude and make your communication effective

- and over 20 years of sales experience that you won't find in any book.

You don't just learn the theory – you put it into practice. In live role-plays, with honest feedback and in a community that strengthens each other.

Learn. Implement. Exchange. That is our fair UNDERSTANDING.

Become part of fairHANDLER and discover how negotiating works your way – confidently, clearly and humanely.

Let's make fair the new strong.

MyCreativeSpark

Unleash your creative voice

I want to see a world full of creativity, where we allow ourselves to express even the craziest ideas. Why? Because it is precisely these crazy or unthinkable ideas that can form the basis for something truly new.

This is exactly where MyCreativeSpark comes in. The app gives you small, unconventional impulses – not as a course, but as a playful nudge to spark your creative energy. All you need is a notebook or sketchbook... and your curiosity.

Because creativity is not a talent that you either have or don't have. It is an attitude, a source of vitality, meaning and freedom – in everyday life, at work and, of course, in art.

What you can expect:

Daily sparks for your thinking
Short, poetic suggestions from art therapy, humour and agile methods – light, surprising and inspiring.
Playful tools & challenges
From the wheel of fortune to the poetic rondo. Sometimes playful, sometimes profound – always an invitation to rediscover yourself. Short reflection questions help you to derive meaning from the game.
Resonance space in the community
In our Telegram group, you will find like-minded people who appreciate depth and humour just as much as you do.

What inspires you?

Because we all feel differently, you will receive impulses that match your inner mood. A short test will show you which key feeling guides you to freedom: clarity, joy, wonder or closeness – each mood opens up a different access to your creative power.

MyCreativeSpark accompanies you back to a time when you did not yet evaluate your creativity – but simply allowed it to flow.

Spenden & Sparen

Do good. Enjoy benefits. Strengthen community.

Many people want to help – but often lack the direct incentive or confidence that their help will actually make a difference. At the same time, small shops, social enterprises and local suppliers struggle for visibility.

Donate & Save combines all these challenges into one solution: a digital voucher book that rewards social assistance with real benefits. Anyone who donates – online or directly to a street vendor – gains access to exclusive offers, discounts and vouchers from committed partner companies.

🔁 £5 donation = £100 voucher value

📱 Conveniently select and redeem vouchers

❤️ Support people & projects that make a difference

The idea came from a personal observation in the Berlin underground: as an introvert, I was deeply moved by the strength of homeless vendors who muster the courage to approach strangers every day. Their energy should be more visible, their impact more rewarded.

With the Proof of Concept of the Entrepreneurship Summit, we want to find out how this idea is received by users and partners – directly, honestly and from real life.

WISSENsREBELL – Learning without yawning.

We come from Karlsruhe (yes, exactly, where Germany's shortest underground railway is located) and we have a mission: to dust off continuing education. No more scripts that look like package inserts and PowerPoint slides that put you in a coma.

Our app is for all continuing education enthusiasts, world changers and exam heroes who are fed up with run-of-the-mill learning stuff. We bring structure to your mind – and wit to your grey cells. You prepare for your advanced qualification (technical specialist, business economist, etc.) and we deliver: practical relevance, charm and a little kick in the butt when Netflix beckons again.

And because we can't get enough of lateral thinking, we've invented our Summit Berlin 2025 Special Product:‘Business Administration in Sexy’. Yes, you read that right. We transform dry business knowledge into material that you not only understand, but actually pass on – without anyone falling asleep. Finally, business administration without the aftertaste of tax forms.

Wissensrebell is not just an app, but your learning partner with a sense of humour. Sometimes cheeky, sometimes charming, sometimes lovingly crazy – but always on your side. We don't take ourselves too seriously, but we take your exam preparation very seriously

In short: if learning were a concert, we wouldn't be the boring recorder club, but the rock band that provides the beat for your career. Ready for a little rebellion in your head? Then grab the app – and finally make further education sexy.
