From startuppers for entrepreneurial minds.

Rubicon – a small river in the north of Italy, where Julius Caesar proclaimed: “alea iacta est” – the dice is cast –  before he crossed the river with his army and triggered the Roman civil war.

Statistically, entrepreneurs make more than five risky decisions every day. And these are real entrepreneurs. Entrepreneurs with experience who understand their work.

When we founded and built our companies, we were in our early twenties. We had no experience and we would not have called ourselves ‘entrepreneurs’. Over the years we’ve made many decisions – both good and bad ones and some that we would not repeat.

We want to help organizations – corporations, academic institutions, public institutions and young companies. We want to help them make the strategically correct decisions, advise on and navigate topics relevant to founding a company and to provide entrepreneurship with heart and mind. Because we have founded companies ourselves, are carved from the same wood and want to share our experience now.

Welcome to rubiconcepts!


We are entrepreneurs.

Everyone has their own story and their own priorities. We started in our early twenties, joining over 20 years of startup experience. In our work in and for start-ups, we were responsible for a combined annual revenue in the double-digit million range. Everyone has their own experiences and yet we have noticed that some patterns, some mistakes and some insights have repeated themselves for all of us. Whether in the consumer, tech or fashion industry.
