Big Data & AI Paris · 2027

Agoris analysis · updated June 2026

Key takeaways

• Big Data & AI Paris is the gathering for IT & Data decision-makers who are industrialising AI, the longest-running data/AI trade show in France in terms of seniority (founded in 2012) and reputation, organised under the high patronage of the President of the Republic, Emmanuel Macron.
• Next edition on Wednesday 29 and Thursday 30 September 2027 at Paris Expo Porte de Versailles, Hall 4. To date, the official website only announces these dates, the venue and the hall for 2027: no edition number, no programme, no announced targets, no rate card.
• Shift confirmed in 2026: visitor access became paid-for, for the first time in the trade show's history, as part of a drive to qualify a large-account decision-maker audience. The 2026 rate card, for reference: Full Pass €1,050 HT as an early bird rate, then €1,150 HT, Basic Pass €40 HT. Target announced by the organiser for 2026: to double the number of qualified visitors from large organisations and to multiply the size of large-account delegations by 2 to 3.
• 3 editorial themes structured the 2026 conferences: Modern Data Architecture, Governance & Regulation, Data & AI for Business, paired with 3 new spaces (Village Advanced Computing, Talent Hub, SME Zone). The 2027 editorial line has not been published.
• Organiser: RX France (Reed Exhibitions) since the acquisition of the assets of Corp Agency in 2023, the agency that created the event in 2012. Year the "& AI" element was added to the trade show's name: 2023, alongside the change of organiser.

Who exhibits

Typical profile

Big Data & AI Paris addresses the entire data and AI value chain within the enterprise:

• Hyperscalers and cloud: AWS, Microsoft Azure, Google Cloud, OVHcloud (French sovereign cloud).
• Data & AI platforms: Snowflake, Databricks, Qlik, Dataiku, Mistral AI (French AI champions showcased in the digital sovereignty strand).
• IT services firms and data consulting: Capgemini, Sopra Steria, Talan, Smile, CGI, MeltOne, alter way.
• CRM and data-driven SaaS: Salesforce and the connected ecosystem.
• Governance, security, MLOps: vendors specialising in data quality, observability and model monitoring.
• Advanced computing: new for the 2026 edition, with a village dedicated to HPC, quantum computing, semiconductors and photonics, whose programme of talks is co-developed with Systematic Paris-Region and Hello Tomorrow.

A deliberate refocusing in 2026: 200 exhibitors and sponsors targeted, compared with 220 brands present in 2025. A logic of curation rather than volume, consistent with the shift to paid visitor access.

Notable exhibitors and recent award winners

The Big Data & AI Innovation Awards are split into 3 categories: Startup, SME / Large Enterprise, Big Data & AI for Good (jury prize, projects serving the public interest).

Recent winners identified:

• 2024: Deema, winner of the Techno Award, an AI platform applied to medical imaging.
• 2023: Iktos Robotics, in the Big Data & AI for Good category.
• 2022 (11th edition): NamR (Startup, geolocated data for real estate), La Javaness (SME / Large Enterprise for the C-in.City project), Holis (Jury Prize).

Visitor quality

The visitor base has historically been highly decision-oriented: CIOs, CDOs, Chief Data Officers, Head of AI roles, and business functions (marketing data, finance data, supply data) from major French and European companies. 2025 edition (1 and 2 October, 14th edition, Hall 3.2): 17,000 attendees announced, 220 exhibitors, 300 conference sessions, focused on digital sovereignty, frugal and responsible AI, and emerging open-source technologies. This figure is a pre-event organiser announcement, not an audited review.

The 2026 Advisory Board, still displayed on the official website, anchored the large-account decision-maker positioning: Chafika Chettaoui (AXA France), Caroline Chopinaud (Hub France IA), Isabel Gomez Garcia de Soria (L'Oréal), Christophe Grosbost (IMA), Claire Mathieu (Suez), Frédéric Pascal (Institut DataIA, Université Paris-Saclay), Aldrick Zappellini (Crédit Agricole group). Organisations announced among the 2026 speakers: Airbus, Accor, Thales, Coface, Bouygues Telecom. No 2027 Advisory Board has been published to date.

Activities & community

The 2026 conference format

The 2026 programme was structured across 3 rooms aligned with the 3 editorial themes:

1. Modern Data Architecture: data platforms, lakehouse, streaming, MLOps, GenAI in production.
2. Governance & Regulation: AI Act, GDPR, data governance, AI ethics, digital sovereignty.
3. Data & AI for Business: business use cases, ROI, the transformation of data-driven organisations.

A mix of formats: plenary conferences, workshops, startup pitches, demo sessions and tech sessions, with an overall target of 350+ speaking slots across 2 days. The trade show's general presentation still promises these three rooms (tech, governance, business), with no detail published for 2027.

Spaces launched in 2026

• Village Advanced Computing: HPC, quantum computing, semiconductors, photonics. Programme of talks co-developed with Systematic Paris-Region and Hello Tomorrow, a strong signal regarding the sovereignty positioning.
• Talent Hub: recruiters, specialist HR platforms and experts on the data / AI skills shortage. A direct response to the bottleneck in the tech jobs market.
• SME Zone: a support space run under the Osez l'IA scheme, with institutional partners, IT services firms, vendors and training providers, addressing SMEs and mid-sized companies at the AI industrialisation stage.

These three spaces were launched in 2026. Their return in 2027 has not been announced to date.

Innovation Awards

3 categories: Startup, SME / Large Enterprise, Big Data & AI for Good (jury prize, projects serving the public interest). The "for Good" category has existed since 2022 and embodies the editorial strand dedicated to frugal and responsible AI, which took shape in 2025. The official website does not publish a call for entries for 2027: in 2026, the formats featured on the programme were the Startup Pitches and the demo sessions.

Community & networks

A strong presence of French AI champions (Mistral AI, Dataiku, OVHcloud), consistent with the digital sovereignty strand. The partnership with Systematic Paris-Region on the Village Advanced Computing connects the trade show to the long-standing competitiveness cluster of the Île-de-France digital sector. The Hub France IA was represented through Caroline Chopinaud on the 2026 Advisory Board.

How much it costs to exhibit

Preparing your visit

For the exhibitor

• 9 months out: make contact with RX France, decide between a stand and conference sponsorship, and position yourself on the value chain (data foundations, AI and analytics solutions, integration).
• 6 months out: apply for the Startup Pitches and the demo sessions, a greater visibility lever than a stand alone for early-stage players. If the Innovation Awards are held again in 2027, the application follows the same timeline.
• 4 months out: align your messaging with the digital sovereignty and frugal AI strand, which the large-account decision-maker visitor base will expect, and with the ROI and production-deployment line pushed by the organiser.
• 3 months out: if you offer HPC, quantum, semiconductors or photonics, request placement in the Village Advanced Computing launched in 2026 with Systematic Paris-Region and Hello Tomorrow, subject to it being held again.
• 6 weeks out: brief the team, activate the matchmaking platform, and prepare live demos (the demo session and tech session format is highly valued).

For the decision-making visitor

• Online registration is mandatory, with a badge that has been paid-for since 2026; anticipate budget approval: the 2027 price has not been published, but the 2026 Full Pass was €1,050 HT as an early bird rate, then €1,150 HT, against €40 HT for the Basic Pass.
• Check what the pass covers: in 2026, only the Full Pass gave access to the conference sessions, with the Basic Pass giving access to the workshops and startup pitches.
• In 2026, the programme was split across 3 rooms (tech, governance, business); the 2027 structure has not yet been published, but targeting one theme rather than flitting around remains good practice.
• Schedule your meetings via the matchmaking platform in advance: with 15,000 attendees targeted in 2026 and 17,000 announced in 2025, walk-in remains inefficient.
• For HR and skills issues: head to the Talent Hub, a space launched in 2026. For SMEs industrialising AI: head to the SME Zone, also launched in 2026. Their return in 2027 has not been announced to date.

Policy & CSR initiatives

The trade show documents concrete commitments on its Our commitments page: 100% of furniture rented and reused, 90% of stand structures reusable, 20 water fountains to cut down on plastic bottles, selective sorting on site and exhibitor awareness of waste management with Re'Up, an ISO 20121-certified caterer sourcing seasonal, French-origin produce and redistributing surplus food to a food aid charity, FSC-certified recyclable kraft badge holders and a brochure printed on 100% PEFC paper. The Big Data and AI Guide moved to a fully digital format in 2025.

On the content side, frugal and responsible AI has been a structuring editorial theme since the 2025 edition, and the Big Data & AI for Good category has existed within the Innovation Awards since 2022. The trade show programmes sessions dedicated to measuring the environmental impact of models, algorithmic frugality, eco-design of code and infrastructure, and AI ethics. The 2026 edition's Governance & Regulation editorial theme extended this logic on the compliance side (the European AI Act, GDPR, data governance).

How the trade show has evolved

Trajectory analysis

Big Data & AI Paris is the longest-running French data/AI trade show: launched in 2012 by Corp Agency at the Cité Universitaire (600 attendees), settled at the Palais des Congrès Porte Maillot from 2013 to 2023, and moved to Paris Expo Porte de Versailles from 2024. The 2023 edition marked a triple shift: the addition of the "& AI" element to the name, the acquisition of the assets by RX France (Reed Exhibitions), and crossing the 16,000-attendee threshold. The 2025 edition structured its editorial focus around digital sovereignty, frugal and responsible AI, and emerging open-source technologies. The 2026 edition was the strategic shift: the move to paid visitor access, a refocusing to 200 exhibitors and sponsors (compared with 220), an Advisory Board weighted towards large accounts (AXA, L'Oréal, Crédit Agricole, Suez, IMA), and 3 new targeted spaces (Advanced Computing, Talent Hub, SME Zone). Reading: RX France is locking in the IT & Data decision-maker positioning during the AI industrialisation phase, against a market of competing trade shows (Tech Show Paris, Data & AI Leaders Summit) attempting to occupy the same niche. For 2027, the organiser has only communicated the framework: 29 and 30 September, Hall 4, marking a return to a late-September slot after the shift to mid-September in 2026. No figures for the 2026 edition have been published to date.
