Amsterdam — Week of 8 Jun 2026

Forrester's CX Summit EMEA is the annual gathering for customer experience, B2C marketing and digital leaders who need more than a conference — they need a change of direction. Three days at Beurs van Berlage, backed by Forrester's research, designed to help leaders turn customer insights into measurable business outcomes. The 2026 summit addresses the real tensions in enterprise CX: fragmented customer journeys, proving ROI to leadership, and aligning CX, digital and marketing teams around a shared direction. Sessions move from strategic frameworks to practical frameworks, with Forrester analysts providing direct guidance rather than vendor pitches. Particularly relevant for heads of digital, CX directors, and CMOs at organisations where customer experience is a board-level priority.

The Amsterdam edition of the world's leading API conference returns to Tolhuistuin for two days on the theme of APIs as the connective tissue between AI, regulation and real services. With 100+ speakers across tracks on API design, security, monetisation, AI-driven automation and the EU AI Act in practice, apidays is essential for engineers, platform teams, architects and product leaders building or governing API-first products. Expect deep technical sessions alongside the kind of cross-company hallway conversations that make this series a fixture of the European developer calendar.

Green IO is the conference for technology leaders who are serious about making IT sustainable — not as a PR exercise, but as an engineering and operational discipline. The 2026 Amsterdam edition arrives at a pivotal moment: generative AI is exploding energy demand across data centres, while European climate policy faces headwinds and tech giants tighten their grip on infrastructure. Green IO responds with high-quality technical sessions — latest research, real-world case studies, deep dives into responsible AI, green software engineering, carbon-aware stacks, green cloud architecture and sustainable hardware. The 150+ attendees are practitioners: engineers, architects, sustainability leads and executives genuinely trying to reconcile performance with planetary cost. Part of the Future of Software Technology conference at Tolhuistuin.

GreenTech Amsterdam is the world's #1 horticulture technology event — the place where robotics in greenhouses, precision growing, climate-control AI, vertical farming, water and energy systems, and ag-data platforms come together. Three days of exhibitions, knowledge sessions and structured matchmaking with market leaders, scale-ups and researchers from across the global horticulture-tech sector. If you work in agritech, foodtech, robotics, sensors/IoT, climatetech or data platforms applied to food production, this is a key event in the European calendar.

PROVADA is the largest real estate fair in the Netherlands and a major meeting place for real estate professionals — but it is also where proptech, smart-building tech, real estate data platforms and digital construction tools find their audience. In 2025 the fair attracted over 27,000 visitors. Worth attending if you build, market, sell or invest in technology applied to real estate, construction or the built environment, or if you work in proptech-adjacent fields (smart buildings, IoT, location data, ESG/energy software).

The day before Hello Tomorrow Summit — Europe's premier deep tech event — lands in Amsterdam for the first time, the city makes its own statement. Amsterdam Deep Tech Showcase is a city-organised day at CRCL Park, Marineterrein, designed to show exactly where Amsterdam has earned the right to play in the global deep tech conversation. Three focus areas: Future of Compute (AI and quantum algorithms); Future of Sustainable Systems (climate tech and green chemistry); Future of Life Sciences & Health (biotech and medtech). Speakers include Mayor Femke Halsema, Guido van Rossum (creator of Python), Kiki Lauwers (CEO, Thorizon), Jelle Prins (co-founder, Cradle) and Sander van Deventer (co-founder, VectorY Therapeutics). An Innovation Market and 10 breakout sessions complete the programme. Brought to you by the City of Amsterdam, with Amsterdam University, VU, Amsterdam UMC and Amsterdam Science Park. Registrations are curated — apply early.

The Benelux Regional final of the Startup World Cup — a global pitch competition with regional rounds in 100+ countries feeding into a Silicon Valley grand finale with a $1M investment prize. Selected Benelux startups pitch to a panel of investors at AI House Amsterdam (powered by Prosus), with the regional winner advancing to the global final in San Francisco later in 2026. A high-quality evening for founders, investors and operators interested in the strongest deep-tech and AI-driven companies coming out of the Netherlands, Belgium and Luxembourg.

After more than a decade in Paris, Europe's leading deep tech summit moves to Amsterdam for the first time. Hello Tomorrow 2026 brings 3,000+ founders, investors, researchers, corporates and policymakers to NDSM Producties — Amsterdam's iconic waterfront industrial space — for two days of serious deep tech programming across 4 stages and 125 exhibitors. The summit focuses on the breakthroughs and strategic priorities that matter most to the deep tech sector right now: healthcare innovation, climate technology, advanced computing, food & agriculture systems, resilience and sovereignty. The Deep Tech Days programme (June 8–10) also runs across Amsterdam this week, offering additional side events for the global deep tech community arriving in the city. This is the flagship event for anyone investing in, building on, or partnering with Europe's most ambitious science-to-market ventures.

Two-day conference at De Kromhouthal in Amsterdam Noord for hands-on engineering leaders — VPs, CTOs, heads of platform, staff engineers — wrestling with how AI actually changes how teams ship software. Day one is talks, panels and case studies from startups through to scale-ups: rethinking engineering roles in an AI-disrupted org, measuring ROI on AI initiatives, managing AI-generated technical debt, developer experience, cognitive load and the supply-chain risk that comes with third-party AI dependencies. Day two flips to an Unconference — attendees set the agenda and bring the hard questions to open peer sessions. Speakers include Anna McDougall (engineering leader and author), Kevin Ball (VP Engineering, Mento), Maxim Salnikov (Senior UX Engineer, Microsoft) and Gregor (fractional CTO). Practical, peer-led, light on vendor pitches.

The main JavaScript conference of the year brings 1,500 developers to Kromhouthal, a former ship-engine factory on Amsterdam's IJ waterfront, for a hybrid in-person day on 11 June followed by an online day on 15 June. JSNation covers the full modern JS stack — frameworks, performance, tooling, AI in the browser and the future of the language — with talks from the engineers actually shaping it. For anyone building web products in JavaScript or TypeScript, this is the room (and the after-parties) to be in.

Two days dedicated to the cutting edge of CSS and front-end craft, held in the 17th-century Zuiderkerk in the heart of Amsterdam. CSS Day is where browser engineers, spec authors and the best front-end developers in Europe gather to go deep on what's newly possible on the web — layout, typography, colour, animation and the features landing in browsers right now. A must for designers and engineers who build for the web and want to stay genuinely ahead, in one of the most atmospheric conference venues in the city.

An unofficial Hello Tomorrow side event held at the STRAAT Museum, pulling in the international deep tech community arriving in Amsterdam that week. Curated showcase of ventures emerging from the DT Launch Pad — a year-long European programme that supports research-based teams from leading universities through training, mentoring and early commercialisation. Short pitches followed by structured networking. No Hello Tomorrow ticket required — this is an open evening for investors, founders and operators who want early visibility on the strongest research-driven deep tech companies in Europe.

Hello Tomorrow week side event at Amsterdam Science Park. Cuts past the AI hype to look at where AI is actually moving the needle on cleantech and sustainability — energy systems, materials, climate modelling. Practical sessions and networking with operators, researchers and climate-tech investors gathered in town for Hello Tomorrow.

The world's largest React conference returns to Amsterdam, drawing 1,500+ in-person attendees and 10,000+ online participants to Kromhouthal for a full day of technical sessions aimed squarely at senior and full-stack engineers. The 2026 edition goes deep on React Server Components in production, the newly released React Compiler and its performance implications, and the rapidly evolving space of AI integration in frontend workflows — prompt engineering for UI generation, LLM-powered product features, and architecting applications that leverage AI without sacrificing performance. Workshops, the legendary React Party, and the Open Source Awards round out the programme. This is not an introductory event: the talks assume production experience and reward engineers who want to work at the edge of what the React ecosystem can do.
