Roadmap to spin-off

We develop a roadmap that leads us step by step to the new company in the market-or, true to the motto "fail fast, fail cheap", to an early termination.

Validated business model

By testing the central assumptions behind your business model, we find out whether we are on the right track even before market entry.

Marketable prototype

As a first milestone in implementation, we build the smallest product that can survive on the market with minimal effort. This allows you to validate your sales and learn from real customer feedback.

Strong brand and inspiring user experience

Whether B2C or B2B, trust comes from strong brands. We design an appearance that promises a lot and a user experience that delivers on its promises.

Targeted market launch

We develop the market launch strategy with you and implement it via social media and advertising campaigns. We enable or support your team in community management and support.

Strategic support for the founding team

As a sparring partner, we support you in strategic issues, set up KPIs to measure success and share our experience in start-up financing, organizational structures, recruiting and HR.
