Arnaud mournetas, Cofondateur et Managing Director de Lise

Arnaud Mournetas

Co-founder and Managing Director of Lise

Arnaud Mournetas is Managing Director and Cofounder of Lise, the French regulated stock exchange dedicated to SMEs and mid-sized companies and the first licensed tokenised stock exchange in Europe. At the head of Lise, he champions a clear conviction: reconnecting savings with the productive economy and making the stock market a driver of reindustrialisation and sovereignty.

An engineer who graduated from Arts et Métiers ParisTech and holds a master’s degree in entrepreneurship, he began his career as a consultant in organisational transformation in the aerospace, industrial and financial sectors. He founded Redstart, an entrepreneurs’ collective and early-stage incubator that has supported around a dozen entrepreneurial projects, and co-founded Kriptown in 2018, one of the first European companies specialising in the tokenisation of financial assets.

This dual background as an engineer and entrepreneur has given him first-hand knowledge of the financing needs of SMEs and mid-sized companies and of their roots in local economies, as well as expertise in tokenisation for capital markets.

    Retail Investment Strategy: a strengthened framework for individuals

    On 18 December 2025, after several years of negotiations, the Council of the EU and the European Parliament reached a political agreement on the Retail Investment Strategy. A reform designed to better protect retail investors against high fees, conflicts of interest in financial advice, and a lack of transparency in investment products.
