European AI leadership spans foundation models, research, developer infrastructure, translation, speech and industrial applications. This is a selected directory, ordered by company name, rather than a measured ranking of influence. Inclusion does not imply that someone spoke at AISB or endorses its programmes.
Which leaders are included?
Use the company sources to check each person's role before outreach. Each row carries its own verification date; company changes are tied to the relevant announcement date. The structured person selection covers the three company roles rechecked on 31 October 2026.
| Leader | Company | Role and field | Company source | Verification |
|---|---|---|---|---|
| Jaroslaw Kutylowski | DeepL | Founder and CEO; language AI | DeepL and publisher | Last verified |
| Mati Staniszewski | ElevenLabs | Co-founder and CEO; speech and audio AI | ElevenLabs | Last verified |
| Demis Hassabis | Google DeepMind | Co-founder and CEO; AI research | Google DeepMind | Last verified |
| Torsten Reil | Helsing | Co-founder and co-CEO; defence AI | Helsing announcement | Last verified |
| Clément Delangue | Hugging Face | Co-founder and CEO; open AI infrastructure | Hugging Face | Last verified |
| Arthur Mensch | Mistral AI | Co-founder and CEO; foundation models | Mistral AI | Last verified |
| Victor Riparbelli | Synthesia | Co-founder and CEO; AI video | Synthesia | Last verified |
This selection covers European origins or substantial European operations. It does not rank companies by revenue, valuation or product quality. Explore the European company directory for the related fields.
How should company updates be checked?
Use dated company announcements for leadership and corporate changes. Mistral AI published an updated company announcement in September 2026. Helsing's July 2026 release identifies Torsten Reil as co-founder and co-CEO. This directory does not publish funding, valuation or revenue figures.
What is the confirmed Aleph Alpha update?
On 16 September 2026, Cohere and Aleph Alpha announced a signed business-combination agreement in an Aleph Alpha company release. This page describes the agreement at the announcement date and does not turn a signing into an unsupported claim that every closing condition has been met.
Use primary company announcements for changes in leadership or corporate structure. Unconfirmed revenue estimates and valuations have been removed from this directory.
Where can I learn from these perspectives?
Match the person or company to the question you need to answer: a research result, a procurement choice and a deployment lesson require different evidence. Compare the conference formats and the European conference shortlist before choosing an event.
For AISB's published 2026 speaker context, see Luc Julia's profile and the speaker directory. For future attendance updates, join the 2027 waitlist. For a company audience, explore a private executive briefing.
