Integrated Systems Europe (ISE) Exhibitor List

ISE is not a single-category trade show. Its exhibitor base in 2025 - 1,605 companies - spans manufacturers of audio and video hardware, signal distribution and control specialists, unified communications and collaboration vendors, digital signage and display companies, broadcast and live production suppliers, lighting manufacturers, and the residential and smart building automation brands whose technology now overlaps heavily with commercial integration work. Alongside them sit software developers, mounting and racking specialists, cabling and connectivity firms, and distributors using Barcelona as a European platform. For anyone building a shortlist for the 2026 edition, the practical question is sector adjacency. A control system brand exhibiting in Barcelona may share buyers with a digital signage CMS developer and a loudspeaker manufacturer, but they will not sit in the same hall or the same conversation. The exhibitor list lets you group companies by the technology they sell rather than by the stand number they occupy, so a meeting schedule can be built around a project - a UC rollout, a stadium audio upgrade, a transport digital signage deployment - rather than around a floorplan.

• Audio, video and signal distribution
• Control systems and AV-over-IP
• Unified communications and collaboration
• Digital signage and commercial displays
• Broadcast, live events and staging
• Residential and smart building automation

The most recent confirmed edition of ISE ran 4-7 February 2025 at Fira de Barcelona Gran Via: 1,605 exhibitors and 85,351 attendees. Those two figures are the honest baseline for the 2026 edition, because the organizer has not published equivalent post-show counts for 2026. What is on the record is Fira de Barcelona's own framing of the coming edition as record-breaking - a statement of intent from the venue operator rather than a confirmed number. That distinction matters if you are buying exhibitor data. A list assembled now reflects companies that exhibited in Barcelona in 2025 plus those confirmed for 2026 as the organizer publishes them; it should not be presented as a fixed 2026 count. Expect additions and withdrawals in the months before the doors open, particularly among smaller distributors and regional resellers whose stand decisions are made late. The safest way to use the numbers is directional: 1,605 exhibitors tells you the scale of the sourcing exercise, and 85,351 attendees tells you why exhibitors keep returning to L'Hospitalet de Llobregat.

• 1,605 exhibitors at ISE 2025
• 85,351 attendees across 4-7 February 2025
• 2026 counts not yet published by the organizer
• Fira de Barcelona has described ISE 2026 as record-breaking
• Expect late additions and withdrawals to the exhibitor base

ISE is held at the Gran Via venue of Fira de Barcelona, Av. Joan Carles I, 64, 08908 L'Hospitalet de Llobregat - a site outside the city centre proper, in the municipality that borders Barcelona. That geography is not a detail: the show's scale, at 1,605 exhibitors in 2025, means exhibitors are distributed across a large, multi-hall complex, and the distance between two meetings can be substantial. For anyone using the exhibitor list to plan a two- or three-day visit, venue structure is as important as company names. Companies cluster by technology family and by the sales channel they serve, so an audio brand, a control manufacturer and a display company chasing the same integrator audience may still be several halls apart. Practical consequences: keep meeting clusters geographically tight, leave buffer time between halls, and treat the Gran Via address as the fixed reference point for travel and accommodation rather than a Barcelona city-centre hotel. Hall-level allocations for 2026 are published by Integrated Systems Events as the floorplan is finalised.

• Venue address: Av. Joan Carles I, 64, L'Hospitalet de Llobregat
• Located outside central Barcelona, beside the city boundary
• Large multi-hall complex at 1,600-exhibitor scale
• Exhibitors cluster by technology family and sales channel
• Build buffer time between halls into any meeting schedule
• Hall allocations published by the organizer as the floorplan is confirmed

Buyers of a pro AV exhibitor list rarely want a directory. They want a filter. A systems integrator preparing for ISE 2026 usually starts with the manufacturers already in their portfolio, checks which of them are exhibiting in Barcelona, and then looks for gaps - a category currently sourced from a single vendor, or a technology they have been asked to quote but do not yet represent. AV consultants use the same list differently: they scan for companies whose product lines intersect with a client brief, then check whether a technical contact will be on the stand during the four days at Gran Via. Distributors and resellers use it to test whether a brand is investing in the European market at all, since appearing at ISE is a commitment signal that a catalogue entry is not. End users - retail groups, transport operators, universities, corporate real estate teams - use it to establish which suppliers exist before writing a requirement. In every case the value sits in grouping by sector, country and product category rather than alphabetically.

• Portfolio gap analysis before booking travel
• Vendor shortlisting against a live project brief
• Testing whether a brand is investing in the European market
• Scheduling stand meetings with technical staff
• Mapping competitors that share the same buyer base

ISE is the exhibition where the professional audiovisual and systems integration industry does its annual European business, and the 2026 edition at Fira de Barcelona Gran Via is the focal point of that cycle. The 2025 figures explain why: 1,605 exhibitors and 85,351 attendees in a single four-day window, covering audio, video, lighting, unified communications, digital signage, broadcast, residential and smart building technology in one location. For exhibitors, that concentration is the reason to commit booth space and staff time. For buyers, it is the reason a single trip can replace months of separate vendor visits. With Integrated Systems Events as organizer and an established base at the Gran Via venue, the structure repeats: sector clusters across the halls, conference programming running alongside the exhibition, and a buyer base that travels from across Europe and beyond. The practical consequence for exhibitor data is that ISE coverage has to be broad by necessity - a list capturing only display manufacturers or only audio brands misses the reason integrators attend at all.

• Four-day window concentrating European pro AV business
• Exhibition running alongside conference programming
• Buyers travelling from across Europe and beyond
• Sector breadth rather than single-category focus
• Organized by Integrated Systems Events at Gran Via

ISE's host city is not incidental to its exhibitor base. Barcelona and the wider Catalonia region have built an institutional relationship with the show: the Ajuntament de Barcelona lists ISE in its economic and district agendas, Barcelona Activa has promoted the 2025 edition through its entrepreneurship programmes, and Catalonia Trade & Investment has used the exhibition as a marker of the region's technology economy. Fira de Barcelona, the venue operator, actively publicises the 2026 edition. For exhibitor research this matters in two ways. First, Spanish and Catalan AV companies - integrators, distributors, manufacturers and installation specialists - use ISE as their home-market showcase, which means the exhibitor list carries a regional layer a purely global directory would flatten. Second, the local ecosystem supplies the technical labour, installation crews and project management that international exhibitors and their customers draw on for Iberian deployments. If you are assessing which exhibitors serve Spanish and Portuguese projects specifically, the Barcelona location is a filter worth applying to the list rather than a piece of background colour.

• Ajuntament de Barcelona lists ISE in its city agendas
• Barcelona Activa promoted the 2025 edition
• Catalonia Trade & Investment treats ISE as a regional marker
• Fira de Barcelona publicises the 2026 edition
• Iberian integrators and distributors exhibit on home ground

Different buyer groups work the ISE floor for different reasons, and the exhibitor list is only useful if it can be filtered accordingly. Digital signage buyers in retail, transport and hospitality scan for display hardware, media players and content management software, and want to know which suppliers will show working installations rather than brochures. Unified communications buyers look for platform vendors, room systems, and the audio and camera peripherals that make hybrid meeting spaces function. Audio buyers in the live and installed sectors look for loudspeakers, amplifiers, DSP and networked audio. Broadcast and production buyers want switching, routing and camera technology. Smart building and residential buyers look for control, lighting and automation that increasingly share protocols with commercial AV. Because ISE 2025 carried 1,605 exhibitors across these categories, the filtering problem is real: a list organised only by company name is close to unusable at this scale. Sector, product category and country are the three cuts that turn a 1,600-company directory into a workable shortlist for 2026.

• Digital signage: displays, media players, CMS
• Unified communications: platforms, room systems, peripherals
• Installed and live audio: loudspeakers, DSP, networking
• Broadcast: switching, routing, camera technology
• Smart building: control, automation, lighting
• Residential systems sharing protocols with commercial AV

A useful exhibitor list for ISE 2026 should identify the companies exhibiting at Fira de Barcelona Gran Via, group them by the technology categories the show is built around, and give enough context - country of origin, website, product focus - for a buyer to decide whether a conversation is worth booking. Because ISE spans audio, video, lighting, unified communications, digital signage, broadcast, residential and smart building, the categorisation has to be multi-label: a company selling AV-over-IP endpoints can legitimately sit in video, networking and control at the same time. Two boundaries are worth stating plainly. Stand and hall allocations come from the organizer and are confirmed as the floorplan is finalised, so any location detail in an exhibitor list depends on what Integrated Systems Events has published at the time of compilation. And conference sessions, keynote speakers and feature zones sit outside the exhibitor directory - they are programme records, not company records. Scope the list to companies, and keep the programme separate.

• Named exhibiting companies at Fira de Barcelona Gran Via
• Sector and product category grouping
• Country and company website detail
• Stand and hall allocation where the organizer has published it
• Conference programme excluded from exhibitor records
• Multi-label categories for cross-disciplinary vendors

Start with what is fixed. ISE is held at Fira de Barcelona Gran Via on Av. Joan Carles I, 64, 08908 L'Hospitalet de Llobregat, organized by Integrated Systems Events, with the official site at iseurope.org. The most recent confirmed edition ran across four days, 4-7 February 2025, drawing 1,605 exhibitors and 85,351 attendees. Dates, opening hours and registration details for the 2026 edition are published by the organizer on iseurope.org. For exhibitor-list users, the practical sequence is straightforward: pull the list early to identify targets, revisit it as the organizer confirms more of the 2026 floorplan, and treat stand locations as provisional until published. The venue sits outside central Barcelona in L'Hospitalet de Llobregat, so plan accommodation and transport around Gran Via rather than the city centre, and allow travel time between halls given the scale of a 1,600-exhibitor show. Where a company's 2026 participation is not yet confirmed, the list should say so rather than presenting a 2025 appearance as a 2026 commitment.

• Venue: Fira de Barcelona Gran Via, L'Hospitalet de Llobregat
• Organizer: Integrated Systems Events; official site: iseurope.org
• 2025 edition ran 4-7 February with 1,605 exhibitors
• 2026 dates and opening hours published by the organizer
