About Lionel LE MAUX

Lionel Le Maux is one of the leading figures in French listed investment dedicated to the ecological transition. At Transition Evergreen, he serves as Chairman and Chief Executive Officer as well as a founder, while also holding a central role at Aqua Asset Management, the management company responsible for the fund’s assets. His career reflects a distinctive blend of asset management, growth investing, and industrial entrepreneurship. A graduate of KEDGE Business School, he began his career in 1996 at Oddo, where he managed French and European small- and mid-cap equity funds. He then moved into entrepreneurship by co-founding Flinvest, an investment management company focused on mid-cap equities, before increasingly shifting toward private markets. This path gave him hands-on experience across both listed markets and growth capital investing, building a profile that bridges portfolio management and company-building. He later co-founded Evergaz in 2008, which became one of Europe’s leading biogas companies. That step marked an important evolution in his career because it deepened his expertise in environmental businesses, energy infrastructure, and long-term platform development. Available sources point to strong operational scaling at Evergaz, reinforcing his reputation for supporting ambitious, complex businesses over time. In 2017, Le Maux founded Aqua Asset Management to invest in medium-sized companies engaged in the ecological transition. Through Transition Evergreen, he champions a long-term investment strategy focused on decarbonization, biogas, energy efficiency, and environmentally oriented businesses. The fund has received the Greenfin and Relance labels, underlining the alignment between its investment policy and ESG-oriented objectives. Transition Evergreen also highlights the entrepreneurial mindset and ecosystem vision that Le Maux brings to the platform. Today, his profile combines listed-company governance, fund management, and sector expertise in environmental investing. In France’s sustainable finance landscape, Lionel Le Maux stands out as an executive able to combine financial rigor, operational insight, and a strategic vision for ecological transition.
