Investing in innovation together

Companisto is the investment platform for startups and growth companies. Business angels and investors participate in groundbreaking innovations, promising companies, and ideas that write history through venture capital. As a fintech company, we stand for lean processes, specialized knowledge, and efficient solutions. We are the driver of innovation in the field of professional online corporate finance. In a diverse society, we assume responsibility for the founding culture in Germany and Europe.

Pioneering Spirit

Pioneering spirit as we understand it is the uncompromising urge and determination to explore new paths to success. Pioneers take risks. Not everyone achieves their goal. But those who succeed have the potential to create great things.

Pioneering spirit develops in outstanding teams and through special personalities. Promising business ideas arise from creativity, assertiveness, and initiative. The ability to turn these ideas into product or process innovations makes it possible to open up new markets. This is the cornerstone for the successful companies of tomorrow.

Companisto is the partner of pioneers.
