What Devoxx UK does
Devoxx UK is an annual two-day software development conference held in London and organised by DMJE Limited, a privately held UK company (registered in England, company number 08481796). Originally rooted in the Java community, the event positions itself as the UK's premier Java developer conference and has progressively broadened its scope to cover wider software engineering topics. The 2026 edition delivered 100+ sessions, hands-on labs, and evening socials across eight core tracks: Development Practices, Java, Architecture, Build & Deploy, People & Culture, Data, Languages, and Mind the Geek, plus a dedicated DevNation Day track hosted by Red Hat Developer. Session formats include 50-minute talks, Byte Size (15-minute) presentations, Mini Labs, and Tools-in-Action sessions.
The conference is built on a community-driven operating model. The website (devoxx.co.uk) runs on WordPress; ticketing is delivered through direct website sales and third-party platforms including Eventbrite, Swicket, and Alf.io; newsletters are sent via Mailjet. Revenue is generated primarily through ticket sales (all subject to UK VAT at 20%) supplemented by a diversified sponsorship portfolio that in 2026 included Red Hat, JetBrains, Redis, Google Cloud, Elastic, Thoughtworks, Capital One, Revolut, TransFICC, Thales, Infobip, TuxCare, Vaadin, Crash Override, and Signify Technology. Strategic partnerships with the Voxxed/Devoxx international conference network and UK user groups (London Java Community, VirtualJUG, Women Coding Community, ArchitectHer, DevIt UK) underpin content sourcing and community reach.
Customer segments centre on software developers, software architects and tech leads, Java/JVM developers, and engineering managers. The go-to-market is event-driven: a single annual in-person gathering in London, augmented by year-round content distribution on YouTube, LinkedIn, Bluesky, Instagram, and Flickr. As of the most recent reporting, the 2026 edition had concluded and organisers were publicly gauging community demand for a possible 2027 edition, introducing material uncertainty about the cadence and continuity of the event series.
