Innovation conferences are large-scale storytelling systems: they gather people around emerging technologies, give organizations a stage, and turn demonstrations into conversations. Recent event figures show the scale of that activity, from CES 2025’s 142,465 attendees to VivaTech 2024’s 165,000 visitors and the more focused 2,400-person LOPEC 2025 audience.

How large are innovation conferences?
The available event reports describe a wide range of conference formats. VivaTech 2024 reported 165,000 attendees, while CES 2025 recorded 142,465. CEATEC 2025 welcomed 98,884, and Web Summit 2024 drew 71,528. These totals describe different events and measurement periods, so they are useful for scale comparisons rather than a single industry average.
Web Summit’s regional Rio edition was smaller but still substantial: Web Summit Rio 2025 drew 34,552 attendees, compared with 34,397 attendees from 102 countries at Web Summit Rio 2024. Collision 2024 reported 1,623 startups, 570 speakers, and 739 investors, but the supplied event facts do not include a total attendance figure for Collision.
At the specialist end of the range, LOPEC 2025 had about 2,400 visitors and around 170 exhibitors. Its conference featured around 150 presentations and speakers from 23 countries. These figures illustrate how an event can be highly concentrated while still presenting an international program.
| Event and edition | Reported attendance | Reported exhibitors or startups |
|---|---|---|
| VivaTech 2024 | 165,000 | 3,500 exhibitors |
| CES 2025 | 142,465 | 4,500+ exhibitors |
| CEATEC 2025 | 98,884 | 810 companies and organizations |
| Web Summit 2024 | 71,528 | 1,261 women-founded startups |
| Web Summit Rio 2025 | 34,552 | 1,397 startups |
| LOPEC 2025 | About 2,400 | Around 170 exhibitors |
The comparison also shows why attendance alone does not define an innovation conference. Exhibitor counts, startup participation, conference sessions, investment funds, and audience composition reveal how an event functions as a marketplace, showcase, or knowledge forum.
Who attends and who exhibits?
CES 2025 provides the most detailed audience breakdown in the supplied figures. Its 142,465 attendees included 81,621 industry professionals, 6,582 media attendees, 54,262 exhibitor personnel, and 158 government guests. The event reported 85,064 domestic attendees and 57,401 international visitors. International attendees represented 40.2% of total attendance, and visitors came from 158 countries, regions, and territories.
The seniority profile at CES was also extensive. The event counted 72,296 senior-level executives, including 16,764 presidents and founders, 13,675 C-level executives, 17,939 vice presidents, senior vice presidents, and executive vice presidents, and 23,918 directors, senior managers, and general managers. CES also attracted representatives from 305 of the 2024 Fortune 500 companies.
CES’s exhibitor ecosystem included more than 4,500 exhibitors and more than 1,400 startups at Eureka Park. It received more than 3,400 Innovation Award submissions, featured 1,100 speakers, and offered more than 300 conference sessions. Those figures connect the physical scale of the show with a substantial program of ideas, demonstrations, and public recognition.
CEATEC 2025 reported 810 exhibiting companies and organizations, including 318 new exhibitors. Its 232 startups, universities, and research institutions formed a substantial part of the event’s innovation-focused presence. The event also included 156 international exhibitors from 29 countries and regions.
VivaTech 2024 reported 3,500 exhibitors and 350+ innovations. The event included 800 investment funds, 47 international ministers and ambassadors, and 40 country pavilions. Its report also recorded 160 nationalities represented, suggesting a broad mix of commercial, public-sector, and international participation.
Where do startups and investors meet?
Startup participation is a recurring measure across the event reports. Web Summit 2024 had 1,261 women-founded startups, equal to 44.5% of its startups. Web Summit Rio 2025 reported 1,397 startups from 43 countries. Collision 2024 hosted 1,623 startups from 57 countries and 739 investors.
Collision also reported 1,762 investor-to-startup meeting requests. This is a more specific measure than attendance: it records an intended connection between capital and companies. It helps show how conference design can support interactions, not only visibility.
VivaTech 2024 reported 450k+ online business interactions and 800 investment funds. Its 3,200 investors and 350+ innovations place investment and product discovery alongside the event’s larger public audience. The same report recorded 88% visitor satisfaction with innovation, a quantified measure of how visitors evaluated the event’s innovation offer.
CES 2025’s 1,400+ Eureka Park startups provide another route into the startup landscape. The show’s industry attendees identified Startups 13,330 times among their interests. In the same audience survey, 41% of industry attendees were B2B buyers, 20.6% were B2C buyers, and 35.9% were both B2B and B2C. These categories describe reported attendee profiles; they should not be added together as mutually exclusive groups.
Which technologies attract attention?
CES 2025 recorded industry-attendee selections across technology and business topics. Artificial Intelligence led with 32,669 selections. IoT/Sensors followed with 17,642, then Vehicle Technology and Advanced Mobility with 16,535, Robotics with 15,565, and AR/VR/XR with 14,936.
Other selected topics included 5G Technologies at 14,340, Smart Home and Appliances at 13,968, Startups at 13,330, Marketing and Advertising at 12,213, and Digital Health at 11,986. These are selections rather than unique people, so they indicate the volume of interest recorded for each topic, not a ranking of exclusive attendee groups.
The event’s program measures add context. CES 2025 featured 1,100 speakers and more than 300 conference sessions, while CEATEC 2025 hosted 222 conference sessions. VivaTech 2024 reported 193 sessions and more than 400 international speakers. LOPEC 2025 reported around 150 presentations, with speakers from 23 countries. Across these events, the program itself is a major part of the innovation story: products and ideas are presented through repeated, structured encounters.
LOPEC’s industry figures require a different reading because they are projections. Its final report projected industry revenue growth of 9% for 2025 and 13% for 2026. These are forecasts for the industry, not measured conference outcomes, and should not be treated as realized growth.
How international are these events?
CES 2025’s 57,401 international visitors came from 158 countries, regions, and territories. Its 6,582 media, analysts, and content creators represented 84 countries, regions, and territories. The media breakdown included 1,044 attendees from Europe, 868 from South America, 381 from North America excluding the United States, 160 from the Middle East and Asia, 41 from Oceania, and 8 from Africa.
Web Summit 2024 reported 2,005 media members from 76 countries. Web Summit Rio 2024 reported 34,397 attendees from 102 countries, while Web Summit Rio 2025 reported 1,397 startups from 43 countries. The different denominators matter: one figure describes attendees, another media members, and another startups.
VivaTech 2024 reported 160 nationalities represented and 40 country pavilions. It identified France as the top visitor country, the United Kingdom as the second, Germany as the third, the United States as the fourth, and Japan as the fifth. CEATEC 2025 had 156 international exhibitors from 29 countries and regions, while LOPEC 2025 had around 170 exhibitors from 29 countries.
These numbers show international reach through several lenses: where visitors come from, where exhibitors are based, how many countries contribute startups, and how many national delegations organize dedicated spaces. They should be read as event-specific measures rather than interchangeable definitions of global participation.
What role do media and sessions play?
Innovation conferences extend beyond the venue through media and online activity. CES 2025 reported 466K social media mentions and a CES global reach on social media of 36B. Its 6,582 media attendees included analysts and content creators, giving the event a documented communications layer alongside its industry audience.
VivaTech 2024 reported 2,600+ accredited journalists, 20k+ press coverage items, and a reach of 2B online users. It also reported more than 450k online business interactions. Web Summit 2024 recorded 2,005 media members from 76 countries. These measures are not directly equivalent: media attendance, coverage items, online users, social mentions, and business interactions represent different kinds of reach.
The program scale is similarly varied. Web Summit 2024 featured 953 speakers. CES 2025 featured 1,100 speakers and more than 300 sessions. VivaTech 2024 had 193 sessions and more than 400 international speakers. CEATEC 2025 hosted 222 sessions, and LOPEC 2025 featured around 150 presentations. Together, these figures describe conferences as dense editorial environments where storytelling, technology demonstrations, and commercial conversations overlap.
CES 2025 also included 22 guests from the U.S. Department of Homeland Security, 7 from the Federal Communications Commission, 6 Nevada state guests, and 4 Washington state guests. Alongside the event’s 158 government guests overall, these figures show that innovation conferences can bring public institutions into the same communication space as companies, startups, investors, researchers, and media.
The result is a multi-layered event format: a physical gathering measured in attendees and exhibitors, a program measured in speakers and sessions, a commercial network measured in investors and meetings, and a media system measured in journalists, mentions, coverage, and online reach.
