The most important tech events in Paris in 2026 are VivaTech, Paris Blockchain Week, SANTEXPO, Eurosatory, ChangeNOW Summit, Big Data & AI Paris, and Trustech. Each serves a different audience, ranging from startups and developers to enterprise buyers, public institutions, and regulated industries. The “best” event depends on whether your goal is visibility, sales, fundraising, technical learning, or long-term partnerships.
VivaTech is the top choice for startup visibility, partnerships, and corporate connections. Paris Blockchain Week is ideal for Web3 startups seeking investors and ecosystem access. ChangeNOW Summit is best for climate, sustainability, and impact-driven startups looking for mission-aligned partners and investors.
React Paris, dotJS, dotAI, NG Baguette, and API Days Paris are the most developer-focused events. They prioritize technical depth, real-world implementation, and peer learning over marketing or sales. These events are best if your goal is improving technical skills, learning from production teams, or staying current with modern development practices.
SANTEXPO, Eurosatory, Trustech, Big Data & AI Paris, and Tech Show Paris are the most procurement-driven events. They attract institutional buyers, CIOs, public-sector decision-makers, and enterprise clients. These events are ideal for companies with mature products, longer sales cycles, and the ability to navigate compliance and procurement processes.
It depends on the event. Developer conferences like React Paris, dotJS, and dotAI focus heavily on content and technical learning. Large expos such as VivaTech, Trustech, and Tech Show Paris generate most value through networking, meetings, and side events rather than stage sessions. Planning meetings in advance is critical.
Yes. During major events like VivaTech, Paris Blockchain Week, and ChangeNOW, the surrounding side events, private dinners, and meetups often generate more value than the main conference itself. Many high-quality conversations happen outside the official program, so attending side events is strongly recommended.
For large events, you should book flights and accommodation at least 4–6 months in advance. If you want to sponsor, speak, or exhibit, planning 6–9 months ahead is recommended. Meetings and side events are usually arranged 1–2 months before the conference.
Most large-scale tech events take place at Paris Expo Porte de Versailles or Paris Nord Villepinte. Developer and niche conferences are often hosted in central venues such as Folies Bergère, CNIT La Défense, or academic institutions like the Sorbonne. Travel time across Paris should be factored into your schedule.
Yes, but you should choose strategically. If you want broad exposure and ecosystem access, VivaTech is the best single choice. For developers, a focused event like React Paris or dotJS delivers higher ROI. For enterprise sales, SANTEXPO or Trustech are more effective than general tech conferences.
Paris hosts tech events throughout the year across different sectors. Attending multiple events makes sense if they serve different goals, such as one visibility-focused event and one highly targeted industry conference. Attending similar events with the same audience often leads to diminishing returns.
Yes. Most major tech events in Paris are international, with English as the primary language for talks and networking. Paris has excellent transport infrastructure, but accommodation fills quickly during major conferences, so early booking is essential for international visitors.
