On 1 January 2022, the four of us (Rutger, Quirijn, Stephan and Mark) started Huygens Quantitative Tax Consulting B.V. It was a true adventure for all of us to set up this beautiful niche firm, focusing on transfer pricing and international tax. On 1 November 2023, our partner Rutger Hafkenscheid will leave Huygens to pursue his career elsewhere. We want to thank him very much for all the efforts he made for the successful start of Huygens. We will greatly miss Rutgerās analytical and academical contributions and wish him all the best in his future endeavours.
