Sir, The proposal is based on the creation of a regulatory sandbox that would allow companies to develop and test new technologies and innovative business models with global potential. Companies would be allowed to operate in the sandbox without regulatory barriers for a limited period of time (2 or 3 years) and within certain financial frameworks (up to €10 million). At the end of the timeframe, an evaluation would follow and adjustments to legislation/procedures would be made to allow the company to operate outside the sandbox. Similar models exist in England, the so-called Sandbox.
