Boomerang Ideas is a Swiss tech start-up, founded in 2019 by Raphael Ueberwasser in Zürich. As an IT specialist and innovation consultant, Raphael observed a common pain amongst his clients: uncertainty in the decision-making process regarding their new business ideas and prototypes, with a ceaseless fear of wasting time, money by failing to meet the market’s needs.
This dilemma inspired his vision to help companies and innovators get instant answers and make risk-free data-based decisions with confidence. Using the power of AI, social media and wisdom-of-crowds combined with micro-targeting, Boomerang Ideas was born.
