Guillaume Aubineau is a co-founder of 373 Avocats & Associés SA.

Guillaume began his career in Paris in the direct taxation department of CMS Francis Lefebvre from 2006 to 2011. During this time, he also spent a seven-month secondment period at CMS Cameron McKenna in London. He then moved to Switzerland where he practised within the tax group of FBT Avocats in Geneva between 2011 and 2013 before co-founding Aubineau Avocats & Associés SA in Geneva in 2014, a firm specialising in French-Swiss taxation, which became 373 Avocats & Associés SA in 2020.
