Best tech conferences in Europe for 2027: the complete guide for professionals and founders

Europe hosts some of the most important technology events in the world. From 70,000-person gatherings in Lisbon to intimate founder-investor matchmaking in Helsinki, the continent's conference calendar covers every corner of the tech ecosystem, including mobile, AI, startups, consumer electronics, cloud, and digital marketing.

This guide breaks down the best European tech conferences for 2027 by focus area, with verified dates, real ticket prices, venue details, and practical tips for making the most of each event.

For mobile and connectivity professionals

Mobile World Congress (MWC Barcelona)

When: March 1-4, 2027 Where: Fira Gran Via, Av. Joan Carles I 64, L'Hospitalet de Llobregat, Barcelona, Spain Attendance: 105,000+ from 207 countries and territories Organized by: GSMA

MWC is the world's largest trade show for the mobile communications industry and has been running since 1987. The 2026 edition marked the event's 20th anniversary in Barcelona, and MWC27 builds on it with six programme themes: Networks Reinvented, AI in Action, Autonomous Enterprise, AI of Tomorrow, Trust at Scale, and The Next Era. Expect AI-native network infrastructure, telco-grade AI, 5G completion, and early 6G work to dominate the agenda.

The event isn't just about phones anymore. For 2027 the GSMA is adding dedicated zones for automotive, health, and aviation, built around live connectivity demonstrations rather than booth displays. A new Connect Health programme, run with Mobile World Capital, brings healthcare and med-tech leaders into the main event. Around 2,900 exhibitors, sponsors and partners take part, and 60% of attendees now come from industries adjacent to telecoms rather than from operators themselves.

First confirmed keynote speakers include Mati Staniszewski (co-founder and CEO of ElevenLabs), futurist Amy Webb of Future Today Strategy Group, Yoon Young Park (CEO of KT Corporation), Caltech professor Anima Anandkumar, and digital forensics expert Dr Hany Farid of GetReal Security. Two satellite events run alongside the main show at Fira Montjuïc: 4YFN for startups and Talent Arena for the developer community.

Best for: Telecom engineers, product managers in mobile technology, IoT developers, and enterprise mobility strategists. If your work touches wireless infrastructure, connectivity, or device ecosystems, MWC is the single most important event on the calendar.

Travel tip: Barcelona hotels near Fira Gran Via sell out months in advance and prices spike during MWC week. MWC26 generated €588 million for the local economy, and accommodation pricing reflects that demand. Booking early through the event's official hotel partners or a dedicated booking platform saves both money and last-minute stress. GSMA members also get 30% off MWC passes, which is worth checking before you buy.

For startup founders and entrepreneurs

VivaTech (Paris)

When: June 16-19, 2027 Where: Paris Expo Porte de Versailles, 1 place de la Porte de Versailles, 75015 Paris, France Attendance: 165,000-180,000 expected Tickets: 2027 pricing not yet published; 2026 passes ran from roughly €180 to €830

VivaTech is Europe's largest technology and startup event, co-organised by Publicis Groupe and Les Echos. The 2027 edition is the eleventh, following the 10th-anniversary show in June 2026 that drew around 2,800 exhibitors, 4,000 investors, and hundreds of conference sessions across 91,000 m² of floor space. The format stays the same: four days of startups, corporates, investors and researchers in one hall, with one day opened to the general public, teachers and students.

What sets VivaTech apart is the direct collaboration between startups and large corporations. The event is structured around open innovation challenges where established companies pose real business problems and startups pitch solutions on the spot. For founders looking for corporate partnerships, not just VC funding, this format is uniquely valuable.

Best for: Startup founders seeking corporate partnerships or investment, innovation leads at large companies, and anyone working at the intersection of deep tech and business transformation.

Travel tip: VivaTech ticket prices rise in tiers as the event approaches, and Paris hotel rates near Porte de Versailles follow the same curve. Porte de Versailles sits on metro line 12, so staying anywhere along that line keeps the commute short without paying venue-adjacent rates.

Web Summit (Lisbon)

When: November 2027, exact dates to be confirmed (the 2026 edition runs November 9-12, and Web Summit typically announces the following year's dates around the close of the current one) Where: MEO Arena and the Lisbon Exhibition & Congress Centre, Parque das Nações, Lisbon, Portugal Attendance: 70,000+ from 160+ countries Tickets: General attendee passes have recently started around €630-€895 in early-bird tiers and risen steeply closer to the event; premium passes run past €4,000

Web Summit is widely regarded as the most important technology gathering in Europe. Founded in Dublin in 2009 and based in Lisbon since 2016, it draws over 1,000 speakers, 2,000+ startups, and more than 1,000 investors across 25+ content tracks covering AI, fintech, climate tech, healthtech, SaaS, media, and developer tools. Recent editions have leaned heavily into AI and robotics, with speakers from Replit, Xiaomi, Unitree, MiniMax and Pony.ai alongside the usual big-tech and VC names.

The programme is structured around themed sub-summits: ContentSummit for media, PandaConf for marketing, SaaS Monster for enterprise software, and FullSTK for developers. Centre Stage keynotes anchor each day, while Night Summit, the official after-hours programme, extends networking into Lisbon's bars and restaurants each evening.

The scale of Web Summit is both its greatest strength and its biggest challenge. With 70,000 people, you need a strategy. Use the Web Summit networking app to schedule meetings at least a week before the event, because popular attendees' calendars fill up fast. Skip the main stage keynotes (you can watch them online later) and focus on the topic-specific stages and roundtables where real conversations happen.

Best for: Founders looking for investment or media coverage, executives tracking the next wave of innovation, and professionals building a global network in tech. Web Summit is the single most efficient place to do all three at once.

Travel tip: Web Summit takes over Lisbon for an entire week, and hotel prices in Parque das Nações and central Lisbon reflect that. The venue is about ten minutes from the airport by metro, so staying slightly further out is practical. Book your hotel near the venue early to lock in a reasonable rate, and check whether the event organizer offers a dedicated hotel booking page with negotiated group rates.

For the London tech ecosystem

London Tech Week

When: June 7-11, 2027 (expo and content stages June 7-9) Where: Olympia London, Hammersmith Road, London, UK, with fringe events across the city Attendance: 30,000+ at the 2026 edition; organisers expect growth in 2027 Tickets: Not on sale yet. The organiser is taking pre-registrations and has not published 2027 prices

London Tech Week is the UK's largest technology festival: three days of expo and stages at Olympia, wrapped in a five-day fringe programme spread across the city's tech hubs and coworking spaces. The 2026 edition introduced the Enterprise World and Start-up World split, six stages, an AI Arena and a VIP Village, and that structure carries into 2027.

The published 2027 content themes are applied AI, AI infrastructure and sovereign compute, enterprise transformation, data and AI excellence, AI safety and ethics, quantum computing, deep tech, space tech and robotics, and tech investment and growth capital. Sector tracks cover AI in retail, AI in finance, and AI in critical infrastructure. The AI Summit London continues as a co-located sub-event focused on commercial AI and enterprise adoption. The 2027 speaker line-up has not been published yet.

London Tech Week works especially well as a multi-event experience. The core conference at Olympia provides structured content and exhibitions, while the week-long fringe programme creates opportunities for more intimate networking and sector-specific deep dives.

Best for: Enterprise tech leaders, AI strategists, fintech professionals, and anyone plugged into the UK and European tech ecosystem. If you're evaluating London as a market, a hiring base, or an investment destination, this is the week to be there.

Travel tip: Olympia sits in the Congestion Charge and ULEZ zones, so driving in is expensive. Kensington (Olympia) station is served by the District line and London Overground, which makes West London and anywhere on the District line a sensible base.

For web, digital culture, and product builders

What happened to TNW Conference

If you attended TNW at NDSM Wharf in Amsterdam, plan differently for 2027. TNW announced in September 2025 that it was winding down its events and media operations, and the June 2025 edition was the last one in Amsterdam. The brand was then bought by the Romanian SaaS company Tekpon, and in January 2026 TNW announced that its flagship conference is relocating to London, alongside a new invite-only format called TNW Gathering held in a handful of international cities. TNW Conference London will sell public tickets, but at the time of writing no date or price has been published. Treat it as unconfirmed until the organiser puts a date on it.

SXSW London

When: May 2027, exact dates to be confirmed by the organiser Where: 20+ venues across Shoreditch, East London, including the Old Truman Brewery and Shoreditch Town Hall Attendance: 40,000+ across the first two editions Tickets: Pass prices vary by tier; early-bird rates open well ahead of the festival

SXSW London is the European edition of the Austin festival and has filled much of the gap TNW left: the same mix of technology, culture, screen and music, in a city campus rather than a convention centre. It launched in June 2025, ran again in June 2026, and the organiser has confirmed a return to Shoreditch in May 2027. The conference, music showcases and screen festival run simultaneously rather than in sequence, so a single pass gets you across tracks in one week.

The appeal is the scale and the setting. It is large enough for serious programming but spread across grassroots venues, which produces a very different experience from a hall at Porte de Versailles or Fira Gran Via. If you work where technology meets creative industries, this is the European event that takes that intersection seriously.

Best for: Product managers, UX designers, founders in media and creative tech, and developers who care about the intersection of technology and culture. If you find Web Summit overwhelming, SXSW London is the right scale.

Travel tip: Shoreditch accommodation is limited and books out, but the festival is walkable from Liverpool Street and Old Street, so anywhere on the Central, Northern or Elizabeth lines works. Check the official dates before booking: the May 2027 window has been announced, but the exact days had not been published as of October 2026.

For consumer electronics and hardware

IFA Berlin

When: September 3-7, 2027 (Friday to Tuesday) Where: Messe Berlin, Messedamm 22, 14055 Berlin, Germany Attendance: Around 220,000 visitors from 140+ countries Exhibitors: 2,000+ from roughly 50 countries across 190,000 m² Tickets: 2027 pricing and opening hours not yet published

IFA is the world's leading consumer electronics and home appliances trade show, running since 1924. Every September, Berlin becomes the global stage for product launches from Samsung, LG, Sony, Bosch, and hundreds of other brands. The 2027 edition will showcase smart home technology, wearables, audio equipment, display technology, mobility, and AI-powered consumer devices.

Unlike software-focused conferences, IFA is a hands-on, product-first event. You walk the exhibition floor and physically interact with prototypes and upcoming devices months before they hit retail. Two sub-events are worth planning around: IFA Next, which showcases startups and research projects, and IFA Global Markets, the B2B sourcing and supplier side of the show.

Best for: Consumer electronics professionals, product designers, retail buyers, hardware engineers, and tech journalists covering the gadget and appliance space.

Travel tip: IFA 2027 runs Friday to Tuesday, which means it straddles a weekend and competes with ordinary city tourism for rooms. Messe Berlin is on the S-Bahn ring at Messe Nord/ICC, so Charlottenburg and the western districts are the practical places to stay.

For AI and data professionals

AI & Big Data Expo Europe

When: 2027 dates not yet announced. The 2026 edition ran October 20-21; recent editions have landed in late September or October Where: RAI Amsterdam, Europaplein 24, Amsterdam, Netherlands Attendance: Around 8,000 over two days, with roughly 300 exhibitors Organized by: Encore Media Group, as part of TechEx Europe

AI & Big Data Expo brings together senior decision-makers, data scientists, and AI engineers to explore real-world applications of artificial intelligence and big data. Sessions cover machine learning deployment, natural language processing, computer vision, predictive analytics, data platforms, and the ethical challenges of AI adoption at scale.

The expo runs as part of TechEx Europe, which co-locates tracks on cloud, edge computing, IoT, cybersecurity and data centres under one roof and one pass. That makes it unusually efficient if your remit spans more than AI alone. The format combines keynotes, panels, and an exhibition floor where vendors demonstrate tools and platforms. It is more commercially oriented than academic AI conferences, which makes it a good fit if you're evaluating tools for your organization rather than publishing research.

Best for: CTOs, data science leads, ML engineers, and enterprise decision-makers evaluating AI adoption. If you're looking for academic AI research, NeurIPS or ICML are better fits; if you're looking for enterprise AI solutions, this expo delivers.

Travel tip: RAI Amsterdam has its own metro and tram stop, and Schiphol is 15 minutes away by direct train. Because the dates move year to year, set a reminder to check the official site in the first half of 2027 rather than assuming a repeat of the October slot.

For the Nordic startup ecosystem

Slush (Helsinki)

When: 2027 dates not yet announced. Slush runs two days in mid-to-late November; 2026 falls on November 18-19 Where: Messukeskus, Helsinki Expo and Convention Centre, Messuaukio 1, Helsinki, Finland Attendance: 13,000+, including roughly 5,500 founders and operators, 3,300 investors, and 250 media Tickets: Recent editions have run from about €595 to €1,195, with tiers rising as the event approaches

Slush is the world's most founder-focused startup event, and it feels nothing like a traditional conference. The signature dark-stage production, concert-like atmosphere, and curated matchmaking create an environment built for one thing: connecting founders with investors.

Every aspect of Slush is designed around quality over quantity. All attending companies must apply and be personally reviewed by the Slush team. The matchmaking platform enables hundreds of structured meetings across 400+ meeting tables at the heart of the venue. More than 500 side events spread across Helsinki during Slush Week, extending networking well beyond the main two days.

Slush is industry-agnostic and early-stage focused. Attending startups span 50+ sectors, with SaaS, healthtech, fintech, AI, gaming, deeptech, medtech, energy, edtech, and manufacturing leading the pack. The Nordic deep tech scene, including the LUMI supercomputer ecosystem, gives the AI and hardware programming real substance.

Best for: Early-stage founders actively fundraising, VCs scouting deal flow, and operators looking to join high-growth startups. If you're a later-stage enterprise or a non-startup professional, Web Summit or VivaTech will be more relevant.

Travel tip: Helsinki in November is dark and cold (think 6 hours of daylight and temperatures near freezing), which is part of the Slush experience. Book accommodation early since the city has fewer hotel rooms than Lisbon or Barcelona, and the conference fills them up quickly. Messukeskus sits next to Pasila railway station, so anywhere on the commuter rail line works. Sort your hotel as soon as your ticket is confirmed.

For the Irish tech scene

Dublin Tech Summit

When: May 26-27, 2027 Where: RDS, Royal Dublin Society, Merrion Road, Ballsbridge, Dublin 4, Ireland Attendance: Around 8,000 from 70+ countries, with 200+ speakers and roughly 160 exhibitors Tickets: Regular passes listed at €245 + VAT for the 2027 edition

Dublin Tech Summit is a high-energy, two-day B2B event mixing founders, investors, and global tech leaders across keynotes, panels, and workshops. Ireland's position as the European headquarters for many of the world's largest tech companies (Google, Meta, Apple, Microsoft, Salesforce) means the local ecosystem punches well above its weight, and DTS reflects that concentration of talent and capital. The 2026 edition marked the summit's 10th anniversary.

The event is more intimate than Web Summit or VivaTech, which makes it easier to have substantive conversations with speakers and attendees. Meetings are booked through the DTS app in 30-minute slots in a dedicated Meeting Zone, and the summit hosts a regional heat of the Startup World Cup pitch competition. The 2027 speaker line-up has not been published yet.

Best for: Founders, investors, and tech professionals with an interest in the Irish and broader European tech ecosystem. Also a good entry point if you're new to the conference circuit and want something less overwhelming than the 70,000-person events.

Travel tip: At €245 + VAT, DTS is the cheapest ticket on this list by a wide margin, so the trip cost is mostly flights and hotel. The RDS is in Ballsbridge, a short DART ride or a 30-minute walk from the city centre, and late May is peak season in Dublin, so book early.

Other notable European tech events in 2027

Latitude59, Tallinn. May 19-21, 2027 at Kultuurikatel. For Baltic and Nordic founders: roughly 3,500 attendees and 800+ investors from 70 countries, one of the strongest investor-to-founder ratios in Europe, plus 40+ official side events.

South Summit Madrid, Madrid. Early June 2027, dates to be confirmed (2026 ran June 3-5), at La Nave in the Madrid Innovation District. For growth-stage founders and corporates: seven thematic stages, a Startup Competition drawing 4,500+ applications, and strong Latin American links.

gamescom, Cologne. August 23-29, 2027 at Koelnmesse. For game developers, publishers and esports: the world's largest gaming event, with gamescom dev on August 23-24, Opening Night Live on August 24, trade and media days from August 25, and public days from August 26.

DMEXCO, Cologne. September 22-23, 2027 at Koelnmesse. For marketing technologists and AdTech: Europe's leading digital marketing conference, with 40,000+ attendees and 700+ partners at the 2026 edition, across Agencies, Commerce, Media and Tech tracks.

Wolves Summit, Warsaw. 2027 dates not yet announced; 2026 ran April 21-22. For CEE founders and early-stage investors: heavy 1:1 matchmaking, pitch sessions, and the European Startup Ecosystem Awards. 2026 passes ran €198-€1,680.

Latitude59 and Wolves Summit are the two to watch if you're a founder looking beyond Western European markets: both sit in ecosystems where capital is less crowded and introductions are easier to get than at a 70,000-person event.

Planning your European conference trip

Attending a conference in another country takes preparation beyond buying a ticket. A few things that experienced conference-goers prioritize:

Book flights and hotels together. European conference cities see massive hotel demand during major events. MWC in Barcelona, Web Summit in Lisbon, and IFA in Berlin all cause hotel prices to double or triple near the venue. MWC alone generated €588 million for Barcelona in 2026, and accommodation is a large share of that. Booking through a dedicated event accommodation platform often gives you access to negotiated group rates and guaranteed proximity to the venue.

Check the dates before you book anything. Several events on this list have not published 2027 dates yet, and one, TNW, has changed cities entirely. Verify on the organiser's own site rather than on a listing aggregator, and watch for format changes: IFA 2027 runs Friday to Tuesday, and London Tech Week splits its expo days from its fringe week.

Buy early, because tickets are tiered. VivaTech, Web Summit, Slush and SXSW London all price in rising tiers, and the gap between the first tier and the door price can be several hundred euros. If you know you're going, the cheapest decision is the early one.

Arrive the evening before. Jet lag from transatlantic flights, delayed connections, and unfamiliar transit systems are all reasons to give yourself a buffer. Reserve your hotel for the night before, get a full night's sleep, and walk into the opening keynote fresh.

Use the event's own booking tools. Many conferences now offer a single platform where you can purchase event tickets and book accommodation in one place. It simplifies expense reports, guarantees proximity to the venue, and often comes with better rates than booking separately on public OTAs.

Plan your meetings before you arrive. Most major conferences (Web Summit, Slush, VivaTech, Dublin Tech Summit) offer matchmaking platforms that let you request meetings weeks ahead. Popular attendees' schedules fill up fast, so waiting until you arrive means missing the people you came to see.

Find your next event

Whether you're a founder chasing investment, an engineer exploring the frontier, or a product leader scouting what's next, Europe's tech conference calendar has something for every stage of your career.
