About Sandborn

We're a team of innovator's and change drivers that love hatching ideas and business to change our world for the better.


We validate and incubate business ideas



We bring validated ideas to market



We support to accelerate growth

Why Sandborn?

We want to hatch great business ideas as we often see that the struggle is not the idea but the execution of building the business. Having helped to build innovative projects and companies, we noticed that the process of ideation, foundation and growth can be learned and replicated and made more efficient by sharing know-how, methods and standardizing processes so that more focus and energy can be allocated toward the core business.

Why the Turtle?

Sandborn was hatched from the insight that like a turtle’s migration from birth to shore, an innovation project begins in hope for levering an opportunity despite facing many vigorous obstacles. A turtle’s strength and risk from the beginning of its life is representative of who we are as strong business builders in the Swiss and European markets. With our passion to cultivate, incubate and accelerate, we will continue to endure these hurdles with our businesses so that we do not only learn from them but maintain a relationship of longevity and achievement.
