Technological independence, voice AI and deeptech entrepreneurship: a look back at the 3rd edition of the Visionaries Club at CentraleSupélec
On Thursday, January 15, the 3rd edition of the Visionaries Club was held at the CentraleSupélec Alumni premises, a now essential event dedicated to deeptech entrepreneurship.
The event brought together alumni entrepreneurs, mentors, leaders of scale-ups and startups supported by 21st by CentraleSupélec, around a common objective: to share concrete feedback on scaling up, technological sovereignty and the close links between research, innovation and entrepreneurship.
The discussions were enriched by leading speakers, offering direct insights into current technological and strategic challenges. Philippe Notton, founder and CEO of SiPearl, reiterated that technological sovereignty is a founding principle of the company, conceived from the outset as a European project supported by the European Union. Dhia Bouajina, Head of Strategy & Operations at GitGuardian, emphasized the pride of being a leading French player in a sector largely dominated by American and Israeli companies. Olivier Teboul, CTO and co-founder of Gradium, highlighted the opening of major new markets for voice AI, particularly in creative content, media, and video games—sectors with a strong demand for personalized interactions.
These discussions were moderated by Sophie Bénard, of ISALT Gestion, and Rodolphe Rosier, PhD, of 21st by CentraleSupélec, whose moderation contributed to the richness of the debates.
The evening also provided an opportunity for Stéphanie Hajjar, Director of Entrepreneurship & Innovation at CentraleSupélec, to thank the community of mentors and experts mobilized alongside the school, and to present a very positive assessment of 2025. More than 200 projects were supported by 21st by CentraleSupélec, including 50 startups in the acceleration phase. The supported startups raised a total of €121 million, illustrating the dynamism of CentraleSupélec's entrepreneurial ecosystem.
As in previous editions, the event concluded with action-oriented pitches from three startups in the accelerator, who came to share their business and strategic challenges with the community:
GoCanopy, specializing in AI for institutional real estate investors, has expressed its ambition to co-create new use cases with European real estate funds.
Letxbe, positioned in no-code automation of bancassurance workflows, seeks to deploy and test its solutions with operations and innovation departments.
Finally, Pipelex, an open-source project dedicated to reliable knowledge pipelines in AI, highlighted its main challenge: enabling virality among developers to accelerate adoption.
