Thomas Doeuff

Thomas Le Doeuff is a Paris-based capital-markets specialist and the Co-Founder and Managing Partner of Aldebaran Global Advisors, an international strategic advisory firm that supports companies, entrepreneurs, and private-equity funds on listing and post-listing strategy. He is an accredited Listing Sponsor on Euronext Paris and, in that capacity, guides SMEs and mid-cap companies through the full IPO journey while also advising founders on seed, Series A, and Series B fundraising strategy.

Before founding Aldebaran, Le Doeuff built his career inside the exchanges themselves — at Euronext and the New York Stock Exchange (NYSE). At NYSE he covered European tech and conducted 8 new US listings of EMEA companies, raising roughly $881m and adding $10bn+ in market capitalization. At Euronext he managed some 15 foreign listings and led tech/digital-sector initiatives, maintaining relationships with 60+ clients. Across his career he has been involved in the listing process for more than 40 companies on Euronext, Euronext Growth, Euronext Access, NYSE, and Nasdaq. Named transactions include La Française de l'Énergie (energy, France, Euronext), Aroundtown (real estate, Luxembourg, Alternext), Luxoft (tech, NYSE), and Eros International (media, NYSE).

On education, Le Doeuff holds a Master's in Management from ICN Business School (also cited as Clermont Business School / a master's from the University of Birmingham in some profiles) and completed an MBA at London Business School (2016–2018).

Note on framing: while the stub lists him under "Angel Investors / Seed Round," his verifiable public footprint is primarily as a founder/fundraising and IPO advisor and Listing Sponsor rather than a prolific check-writing angel. Founders should treat him as a capital-markets and fundraising partner who works at the seed-to-listing continuum.

• Works with founders "at seed stage or through Series A and B rounds" to shape and execute fundraising strategy (per the firm's stated services).
• As a Euronext-accredited Listing Sponsor, specializes in taking SMEs and mid-caps public — IPO preparation, listing-venue selection, and post-listing strategy on Euronext Growth/Access, Euronext, NYSE, and Nasdaq.
• Sector-agnostic in practice, with demonstrated comfort across energy, real estate, tech/digital, media, pet services, and mining.
• Value-add is exchange-side expertise: he has sat inside NYSE and Euronext and knows what listing/investor-relations readiness actually requires — a differentiator versus generalist advisors.
• Aldebaran also advises the firm's partner Sébastien, a venture-capital expert (10+ years, consumer/sports/media/entertainment/gaming/healthcare), giving the practice added early-stage VC bench strength.
