The Paris data and AI trade show created in 2012 and run by RX since 2023, which ends free entry in 2026 to court large-company data leaders.
An annual two-day trade show and conference on data and artificial intelligence, aimed at the people who buy and run data and AI platforms in large French organisations, held in Paris and organised by RX France. It started in 2012 as Big Data Paris, later absorbed the AI Paris show to become Big Data & AI Paris, and passed to RX in 2023 when RX bought its founder, Corp Events. The 2026 edition was the 15th and the 2027 edition is the 16th. The organiser describes it as the meeting place for IT and data decision-makers who are industrialising AI, it runs under the high patronage of the President of the French Republic, and for the first time every visitor badge is paid. Events Index files it under Big Data, Artificial Intelligence & Machine Learning, and AI, with a national rather than international audience base.
29–30 September 2027. Opening hours for 2027 had not been published as of 26 October 2026; the 2026 edition ran from 9:00 to 18:00 on both days, with exhibitors admitted from 8:00. Paris Expo Porte de Versailles, 1 place de la Porte de Versailles, 75015 Paris. The 2027 hall had not been confirmed as of 26 October 2026; the 2026 edition, on 15 and 16 September 2026, was in Hall 7.2, a change from earlier years: the 2025 edition ran on 1 and 2 October 2025 in Pavilion 3 of the same exhibition centre, the 2024 edition on 15 and 16 October 2024, also in Pavilion 3, and the 2023 edition on 25 and 26 September 2023 at the Palais des Congrès de Paris. Anyone working from an older calendar entry should check the hall number before arriving.
RX France, the French subsidiary of RX (the former Reed Exhibitions), itself part of the RELX group. RX France also runs MIPIM, MIPCOM, Batimat, Pollutec, EquipHotel and Paris Photo. Big Data & AI Paris was created in 2012 by Corp Events, the Paris company led by Olivier Cadi, which also ran Big Data & AI Toronto, the World AI Cannes Festival and Quantum Business Europe; RX announced the purchase of Corp Events on 26 July 2023. The show director is Émilie Pierre-Desmonde. The official site's footer names the operating entity as RX (Reed Exhibitions Limited), while ticket sales are governed by the terms of RX France SAS.
The organiser targeted 15,000 participants for 2026, alongside 200 exhibitors and sponsors; these were forward-looking organiser targets, not counted attendance. No target had been published for 2027 as of 26 October 2026. The audience the show is built for is IT directors, CDOs, CIOs, CTOs, heads of data, data platform managers, governance leads, innovation and business-line directors and transformation managers in large French companies and mid-caps, with data scientists, data engineers, architects and AI and machine learning leads beside them, and on the exhibitor side the data, AI and cloud vendors, consultancies, integrators, training providers and startups selling to them. For 2026 the organiser says it is targeting France's 400 largest companies, wants to double the number of qualified visitors from large organisations and to multiply the size of large-account delegations by two to three, with delegations of 10 to 30 people. Visitors may be asked to prove professional activity when registering. No breakdown of the audience by job title, company size or country is published.
No speakers had been announced for 2027 as of 26 October 2026. For 2026, the organiser announced 300 speakers, but the official speakers page did not render a readable roster, so the list below is limited to names the organiser published in its press releases for that edition.
Advisory board (published roster):
First speakers announced (press release of 6 May 2026):
The organiser's 3 June 2026 release adds organisations expected on stage without naming individuals: Crédit Agricole, Bouygues Telecom, Crédit Mutuel Arkéa, Groupe Etam, H Company, Inria, Caisse des Dépôts, URSSAF, Linxens, CEA, Airbus, Accor, Suez, Thales, SNCF, AXA France, the DATAIA Institute and Coface. Speakers reported for the 2025 edition, including Cédric Villani, are not confirmed for 2026.
Changes for the 2027 edition had not been announced as of 26 October 2026. For reference, the 2026 edition brought five changes against 2025. First, access: the free Pass Salon of 2025 was gone, and every visitor had to buy either a Basic Pass or a Full Pass. Second, the calendar and the floor: mid-September instead of early October, and Hall 7.2 instead of Pavilion 3. Third, the conference programme is regrouped into three editorial tracks and steered by a six-member advisory board of enterprise data leaders. Fourth, a new matchmaking platform lets visitors identify, qualify and book one-to-one meetings with exhibitors before the show, with dedicated help for Full Pass holders. Fifth, two new areas: the Advanced Computing Village, for high-performance computing, quantum, semiconductors and photonics, and the Talent Hub, for recruiters, HR systems vendors and data and AI team building. The SME zone, launched in 2025 and tied to the government's Osez l'IA programme, returns. The headline targets also shrink: 15,000 participants expected for 2026, against more than 17,000 announced for 2025.
The 2027 programme had not been published as of 26 October 2026. The 2026 paid conference programme ran in three editorial tracks: Modern Data Architecture (building a modern, scalable, governed data architecture), Governance and Regulation (data and AI governance aligned with regulatory compliance), and Data and AI for Business (practice and case studies with measurable business results). The organiser's announced themes for 2026 were agentic AI and autonomous agents under control, conversational systems at scale, AI at scale and moving from proof of concept to production, data governance and data quality, regulatory compliance and security, sovereignty from data down to chips (dependence on hyperscalers, cloud architecture, European open source, compute and hardware), real-time data platforms at industrial scale, infrastructure costs and ROI, MLOps, and the organisation of data offices. Around the conferences sit more than 200 workshop sessions in five rooms, 50 startup pitch sessions, the Advanced Computing Village programme co-developed with Systematic Paris-Region and Hello Tomorrow, and tech sessions. The organiser's total is 350 conferences, workshops, demonstrations and pitches. A session-by-session agenda was not readable on the official site on 10 September 2026.
Six formats. Strategic conferences, including keynotes, round tables and case studies, reserved for Full Pass and VIP badge holders, with no pre-registration: the badge is the ticket. Workshops, more than 200 sessions in five rooms where vendors show solutions, open to every pass. Startup pitches, 50 short sessions, open to every pass. Tech sessions and the Advanced Computing Village talks. Pre-booked one-to-one business meetings through the matchmaking platform, available to both paid passes. And the exhibition floor itself, with the SME zone and the Talent Hub. The call for speakers states that conference slots cannot be commercial presentations and favours case studies already deployed and industrialised.
No official side events, evening receptions or satellite meetings were published for 2026, and none had been published for 2027 as of 26 October 2026. The details below describe the 2026 edition. Everything the organiser lists sits inside Hall 7.2 and inside the ticket: the Advanced Computing Village, the Talent Hub, the SME zone, the workshops and the startup pitches are open to Basic Pass and Full Pass holders alike, while the strategic conferences and premium lounges need a Full Pass. The show is not part of a multi-show RX week: no other RX France event shares its dates, and no Big Data & AI Paris badge admits to another show. The event sharing the exhibition centre that week is NRF Retail's Big Show Europe, from 15 to 17 September 2026, which is run by Comexposium and the US National Retail Federation, sold separately and unrelated to Big Data & AI Paris. The next RX France show at the same site, Paris Builders Show, a construction trade fair spread over several halls including Hall 7.2, opens twelve days later, from 28 September to 1 October 2026, and is equally unrelated. The organiser also publishes The Big Data & AI Insiders, a free downloadable magazine, which is content rather than an event.
Prices for 2027 had not been published as of 26 October 2026. The 2026 edition had two paid visitor passes, prices excluding VAT. Full Pass: 1,150 EUR excl. VAT, the Full Price tier running until 14 September 2026, shown on the site against a struck-through 1,250 EUR; it includes all strategic conferences, access to speakers and decision-makers, the exhibition, the five workshop and startup pitch rooms, personal help to organise business meetings on the matchmaking platform, and premium areas with meeting space and catering. An early bird Full Pass at 1,050 EUR excl. VAT closed on 12 July 2026 and is no longer available. Basic Pass: 40 EUR excl. VAT, covering the exhibition, the five workshop and startup pitch rooms and the matchmaking platform, but not the conferences. The registration page lists an on-site price tier for 15 and 16 September without stating the amount. A VIP Pass is mentioned in the FAQ as giving conference access, with no public price or sale route. Press passes are free on accreditation. Group and enterprise delegation rates are negotiated: contact Sarah Testevuide at RX France, whose rxglobal.com email address is given on the registration page. For comparison, 2025 visitors could enter the exhibition free with a Pass Salon and paid only for conference passes.
Through the Call for Speakers form on the official site. The organiser wants a demanding programme centred on experience: conference talks can never be sales presentations or product showcases, the preferred format is a concrete case study already deployed and industrialised, and startups or vendors may submit a real use case only if it is co-presented with the client concerned. All proposals are reviewed and only candidates retained for the next selection step are contacted. Accepted speakers get a Full Pass Speaker, with access to conferences and networking areas, and promotion on the organiser's channels; travel and accommodation are at the speaker's expense. No submission deadline is published, and no 2027 programme timetable had been published as of 26 October 2026. Exhibitors reach the workshop and pitch rooms through their exhibitor package rather than this call.
Through the "become an exhibitor or sponsor" contact form on the official site, after which the sales team calls back; the organiser's customer line is +33 1 47 56 65 20, Monday to Friday, 9:00 to 18:00. Three routes are published: the standard exhibitor and sponsor offer, a startup programme with a startup zone and pitch slots, and the SME zone supported by Osez l'IA, aimed at vendors selling to SMEs and mid-caps. No stand prices, stand sizes, package names or booking deadlines are published. The organiser's pitch to exhibitors is audience quality: France's 400 largest companies, structured delegations of 10 to 30 people and pre-booked meetings. Existing exhibitors manage logistics through the Exhibitor Hub, and the 2026 on-site exhibitor welcome desk sat inside Hall 7.2 facing stand AC01.
No 2027 sponsor list had been published as of 26 October 2026. The official 2026 sponsor page listed 21 sponsors in five tiers:
Separate from sponsorship, the site lists editorial partners (the DATAIA Institute of Université Paris-Saclay, Hub France IA, IMA), institutional partners (the Ministry of the Economy through Osez l'IA, La French Fab, Bpifrance, Agora Managers, IMA, aivancity, Women in Big Data Paris, Femmes dans l'IA, Systematic Paris-Region, CPME, French Tech Corporate Community, Numeum, Welcome to the Jungle, Cabinet GTEC of Groupe Purpl, ESSEC Alumni, G9+) and 21 media partners, listed under press coverage below. The organiser targeted 200 exhibitors and sponsors in total for 2026; the exhibitor directory page did not render a readable list on 10 September 2026.
Not publicly disclosed: the organiser publishes no breakdown of exhibitors or visitors by company type, size or sector. The published material shows the mix. On the exhibitor side, global cloud and software groups (Google Cloud, Microsoft, Oracle, IBM, Orange Business, Informatica), data platform and database vendors (Dremio, Neo4j, Progress, Kong, Popsink, Safe, Suadeo, Digda, Blueway), consultancies and agencies (Square Management, Ekino), and startups in the pitch programme. On the visitor side, the stated targets are CAC 40 groups, large companies and scale-ups, and the speaker organisations named for 2026 come from aerospace, hospitality, environmental services, telecoms, banking, insurance, public administration, research and industry.
By emailing Joanna Kirk, the show's tech press relations manager, at joannakirkpr@gmail.com, giving your name, outlet and full contact details, or through the Press Pass request button on the registration page. The FAQ states that press badges are subject to moderation by the show. The Press Pass is described as reserved for journalists and content creators, and the organiser's June 2026 release says accredited journalists get full access to the conferences and every area of the show. No accreditation deadline is published. Two 2026 press releases, dated 6 May and 3 June 2026, and a photo gallery sit on the press page.
Most of what is findable for 2026 either comes from the organiser's two press releases or runs in outlets on its media partner list, which reads: Alliancy (media partner), Archimag (media partner), Le Big Data (media partner), Business Times (media partner), Code Confiance (media partner), Décideurs Magazine (media partner), DevITjobs (media partner), EcoRéseau (media partner), FinanceX Magazine (media partner), Grand Prix ACF AutoTech (media partner), IT for Business (media partner), La Revue du Digital (media partner), Le Figaro (media partner), LeMagIT (media partner), Le Point (media partner), L'Informaticien (media partner), Maddyness (media partner), Silicon (media partner), Solutions Numériques (media partner), Stratégies (media partner) and L'Usine Digitale (media partner). The repositioning was reported by Pro Event Insight on 12 May 2026 and by IT Social, both closely following the 6 May release, and event listings ran in IT for Business (media partner), Solutions Numériques (media partner) and Archimag (media partner). In earlier years, IT for Business (media partner) broadcast live from the 2023 and 2024 shows, ActuIA published a pre-show interview with Émilie Pierre-Desmonde in 2025, and the 2023 RX acquisition was covered by Exhibition News, Exhibitor Online, Decideo and Le Big Data (media partner).
Weak as independent evidence. On the four levels used in this index: placed coverage is the bulk of it, since 21 outlets, including national titles Le Figaro (media partner) and Le Point (media partner), are listed as media partners and every mention there is part of a partnership; organiser-claimed material is the rest, since the scale figures, the targets and the speaker names all originate in RX's own releases, which trade outlets such as Pro Event Insight and IT Social restated rather than tested; predictable but unconfirmed coverage comes from journalists on free press passes, which commit no one to publish; genuinely independent reporting that questions the organiser's figures or the paid-access decision was not found for 2026. The consequence is that no number on this page has an outside check.
Because RX has decided that exhibitors will pay more for fewer, better-qualified visitors than for a crowd. The evidence is in the organiser's own numbers: the 2025 edition was sold on a free exhibition badge and announced more than 17,000 participants, while the 2026 target is 15,000, a smaller headline figure published alongside a goal to double qualified visitors from large organisations. The 40 EUR Basic Pass is too cheap to be a revenue line and works as a filter against casual walk-ins, and the 1,150 EUR Full Pass puts the conferences out of reach of anyone whose employer has not signed off. The gamble is visible on the sponsor wall, where Google Cloud, Microsoft, Oracle and IBM sit in the top tiers: they are buying access to CDOs from the 400 largest French companies, and the show will be judged on whether those delegations of 10 to 30 people actually arrive, a figure the organiser has not promised to publish.
Because every figure is a forecast written by the organiser, and the forecasts move from year to year without any published count behind them. For 2024 the show was announced at 20,000 visitors, more than 230 exhibitors and nearly 700 speakers. For 2025 the announcements said more than 17,000 participants, 220 exhibitors and 300 speakers, while the venue's own listing repeated nearly 700 speakers and more than 300 presentations. For 2026 the release says 15,000 participants, 200 exhibitors and sponsors, 300 speakers and 350 conferences, workshops, demonstrations and pitches, a total that includes more than 200 vendor workshop sessions and 50 startup pitches, so the conferences proper are a minority of it. No audited attendance figure for any edition was found in the sourced material, and a previous version of this page mistook a forecast for a closing result. Read the numbers as a statement of ambition, and the drop from 17,000 to 15,000 as the one signal that is deliberate.
Vendors hoping to pitch from a conference stage: the call for speakers bars commercial presentations and demands a client co-presenter. Speakers looking for a 2027 slot: no 2027 call for speakers timetable had been published as of 26 October 2026, so the programme cannot yet be assumed to be open. Visitors who only want the talks on a small budget: in 2026 conferences needed the Full Pass at 1,150 EUR excl. VAT, and the 40 EUR Basic Pass covered only the exhibition, vendor workshops and pitches; 2027 prices had not been published as of 26 October 2026. Buyers who need flexibility: RX France's badge terms make purchased badges non-refundable. International visitors who do not follow French: the programme material is published in French first and no interpretation is announced. Engineers after deep open-source or research content: the format is a vendor exhibition with enterprise case studies, not a developer or academic conference. And anyone hoping for a documented audience profile before committing a budget, since none is published.
It is the French national data and AI trade show of the autumn, and one of three data and AI events RX runs across Europe. In 2026 it opened the autumn season in Paris in mid-September, and the 2027 edition is set for the end of September. One week later in 2026, RX ran Big Data LDN at Olympia London, on 23 and 24 September 2026, a separate event with its own ticket that the Big Data & AI Paris site links as a sister show. RX France's other AI event is the World AI Cannes Festival, set for 10 and 11 February 2027 at the Palais des Festivals in Cannes, which is international where Paris is national. In Paris itself, the only large event sharing the exhibition centre on the same dates in 2026 was NRF Retail's Big Show Europe, a retail show from another organiser. Events Index tracks Big Data & AI Paris in its AI and data vertical.
No current one. The brand had a Canadian sibling, Big Data & AI Toronto, run by Corp Events and later described as organised by Corp, an RX company; no edition after its October 2023 show at the Metro Toronto Convention Centre was found in the sourced material, and its former website no longer resolves. The Big Data & AI Paris site links Big Data LDN, the RX show in London on 23 and 24 September 2026, which is a sister event under a different brand, not a London edition of the Paris show. Quantum Business Europe, also acquired with Corp Events, has no 2026 edition found.
Mainly French (unverifiable information): the organiser publishes no language policy for sessions, but the call for speakers, the FAQ, both 2026 press releases and the conference track descriptions are written in French, the site's French version is the primary one, and the named 2026 speakers and advisory board are almost all from French organisations. An English version of the official site exists, and no simultaneous interpretation is announced. International visitors should expect French on most stages.
Not publicly disclosed for 2026: no virtual ticket, livestream or replay policy appears on the official site, and every pass sold is an on-site badge. The show runs a YouTube channel under the name BiG DATA & Ai PARIS, and media partner IT for Business (media partner) published replays of its live broadcasts from the 2023 and 2024 editions, but neither is a commitment to record the 2026 conferences. The 2023 edition at the Palais des Congrès was also offered on a digital platform; no such platform is announced for 2026. RX's admission policy states that official photographers and film crews may record and stream at its shows, and that visitors may not record without written permission.
No refunds. RX France's general terms for badge sales, dated 6 February 2024 and not linked directly from the Big Data & AI Paris site, state that purchased badges cannot be returned, refunded or exchanged, even if lost or stolen; that online orders are firm and final; that the buyer gets no compensation if the show is changed, postponed or cancelled for any reason, and bears their own travel and hotel costs; and that the organiser may refuse any change to a badge. Resale is prohibited. The show's own pages add two points that do not fully agree: the FAQ says a badge is personal and cannot be transferred, while the registration page says a ticket can be reassigned to another person up to two weeks before the show by writing to Sarah Testevuide at RX France, whose rxglobal.com address is on that page. Two weeks before the show fell on 1 September 2026, so even that route has closed for this edition.
Partly documented. The FAQ states that Paris Expo Porte de Versailles facilitates access for people with reduced mobility and offers a downloadable access plan for Hall 7, and the practical information page links RATP's accessible routes and a reduced-mobility access guide. Nothing is published on sign language interpretation, live captioning, hearing loops, quiet rooms, assistance dogs or a named contact for access requests; the general customer line, +33 1 47 56 65 20, is the only route given. Under-18s are admitted only by exception with the organiser's prior written authorisation.
Big Data & AI Paris is held at Paris Expo Porte de Versailles, 1 place de la Porte de Versailles, 75015 Paris (the 2026 edition was in Hall 7.2; the 2027 hall had not been confirmed as of 26 October 2026), in the 15th arrondissement on the southern edge of the city. By metro, line 12 to Porte de Versailles or line 8 to Balard; by tram, T2 or T3a to Porte de Versailles; by bus, lines 80, 39 and PC1. From Charles de Gaulle airport the organiser gives RER B then tram T3a, about 40 minutes; from Orly, metro line 14 then tram T3a, about 55 minutes. Drivers can use car parks P1, P6 and P7. There is a cloakroom at the show entrance. The organiser's partner bnetwork offers preferential hotel rates and Air France KLM a promotion code of up to 10 percent. Badges must be printed: they become available 15 days before the show, and printing in advance avoids the on-site queue. A visa invitation letter can be downloaded from the registration confirmation email.
