TL;DR — Marseille's tech calendar centres on two September blockbusters: AIM (AI conference, Sep 24–25 at the Orange Vélodrome, ~5k attendees[1]) and Le Grand Bain (French Tech annual gathering, Sep 14 at Palais du Pharo, ~1,800 attendees[2]). For year-round access, the Tech Mixer runs free every Friday evening at LOCHNESS — no registration needed.[3] The city punches modestly relative to Paris or Lyon on pure conference volume, but its September window is genuinely strong.

Flagship Conferences

AIM – Artificial Intelligence Marseille[1]

Sep 24–25, 2026 · Orange Vélodrome · ~5,000 attendees · Paid

Marseille's biggest tech event, now in its 4th edition. AIM fills the Vélodrome stadium for a deliberately immersive format: keynotes are delivered from the pitch itself. Theme for 2026: "THE BIG SHIFT — The Great Acceleration", addressing AI's economic and geopolitical implications — chip races, data sovereignty, energy costs of compute. Organised by La Tribune, BFM TV, and CMA CGM Media; the 2025 edition drew 100+ speakers and 500+ structured business meetings.[1] Tickets: aim.vimeet.events/fr/tickets.[11]

Community Gatherings

Sep 14, 2026 · Palais du Pharo · ~1,800 attendees

La French Tech Aix-Marseille's flagship annual gathering, staged at the Palais du Pharo with panoramic views over the Vieux-Port.

The 7th edition drew 1,800+ participants across the startup ecosystem, banks, and training organisations.[2]

DevFest Marseille 2026: Workshop Edition[9]

Nov 12, 2026 (evening) · GDG Marseille · Free

Part of the global DevFest network[12] of community-run Google Developer Group events. The 2026 Marseille edition is a focused "Workshop Edition" — an evening of hands-on coding, structured to simultaneously launch the newly independent GDG Marseille chapter (previously operating as GDG Aix-Marseille).[9] Expect a smaller, high-participation format rather than a full-day conference.

Developer Meetups

Every Friday, 6 PM · LOCHNESS (2 Cours Jean Ballard, 13001) · Free

Weekly afterwork for Marseille's tech workers — devs, data scientists, product managers, students, and career changers. Casual format: drinks at the bar, no agenda, no speakers. Best entry point for a visitor who wants to plug into the local scene without committing to a full event day.[3]

Deep Tech & Specialized
