[Web](https://www.wearedevelopers.com/world-congress) Technology & ITArtificial Intelligence Joaquín Montesinos • Published October 25, 2026 AI is reshaping how engineering teams design, ship and operate software. From 14 to 16 July 2027 Berlin hosts WeAreDevelopers - World Congress 2027, a large-scale event for developers, AI builders and tech leaders focused on practical adoption. ## Dates, venue and scale WeAreDevelopers - World Congress 2027 runs from 14 to 16 July 2027 at Messe Berlin. The format combines a sprawling tech expo with numerous stages dedicated to engineering, AI and security. Public figures for the event include 15,000+ builders, 8,000+ companies, 500+ speakers, 20+ stages and over 40,000 square metres of expo space. ## Key numbers to size the audience Official numbers highlight the mix of technical profiles and decision-makers: 15,000+ builders, 8,000+ companies and 2,000+ decision-makers. That scale means a high concentration of platform teams, ML engineers, SREs and product leads evaluating vendors and architectures. ## Program highlights The agenda emphasizes hands-on and operational topics. Published program elements cover tech talks, live coding, workshops and an extensive tech expo. Core themes include coding agents, agentic systems in production, latency and cost trade-offs, testing non-deterministic systems and observability for AI features. Previous editions have featured senior industry figures; the 2027 lineup will complete the speaker roster for this edition. ## Attendee profile and company types Expect a mix of backend and frontend engineers, ML and platform engineers, QA and security specialists, and engineering leaders assessing build versus buy decisions. Exhibitors range from AI tooling vendors and cloud providers to specialists in vector databases, observability and app security. ## Practical steps for B2B outreach at the congress Use the event app to prebook meetings and filter exhibitors by technical criteria. Prepare a short set of technical qualifiers for demos: API compatibility, latency targets, GPU requirements and integration constraints. For vendor comparisons, schedule 20 minute demos and request a minimal proof of concept against a representative dataset. Bring concrete evaluation metrics so technical and commercial stakeholders can align during follow-ups. ## Making the three days count Given the expo size and number of stages, split time between demos at the expo and targeted sessions that address your immediate operational issues. Workshops are the opportunity to validate a pattern in person; reserve capacity to follow up with a technical contact for testing after the event. ## Final note and official link WeAreDevelopers - World Congress 2027 frames operational questions that are already on many engineering roadmaps: how to govern agents, how to observe model-driven paths and how to test nondeterministic features. If your roadmap includes platform, security or data stack decisions, Berlin will provide a dense field of vendors and case studies to contrast.
