Product Readiness. Market Readiness. Investment Readiness. People Readiness.


Our program will empower you with the knowledge and skills you need in your entrepreneurial journey. With our intensive 8-month cohort program, we offer a transformative experience that will equip you with the essential tools to take your startup to the next level.

Through a carefully crafted curriculum including expert-led Masterclasses, Workshops, and Coaching, we cover everything from customer discovery and product development to growth strategies and investor pitching. You'll gain invaluable insights from industry experts, successful entrepreneurs, and seasoned mentors who will guide you every step of the way.


As a participant in our program, you'll receive €2.2K per person per month (allowing up to 5 founders per team) - up to €88k, giving you the runway to validate your ideas and execute your business plans.

In addition to the funding, we offer a range of perks and benefits that will help your daily operations, including access to exclusive resources, discounted services, and strategic partnerships.


Location matters when it comes to building a successful startup, and we've got you covered. As a participant in our program, you'll gain access to one of Berlin's best co-working hubs. This means you'll be surrounded by like-minded individuals and innovative companies.

Immerse yourself in a collaborative environment where ideas flow freely, and connections are made effortlessly. The infrastructure we provide goes beyond physical space; it's a supportive community that fosters creativity, growth, and meaningful relationships.
