Upcoming
AI Tinkerers Lisbon and PostHog will host a practical, code-driven demo night. Engineers will share production AI builds and lessons learned, with PostHog sponsoring.
Past
Builders gathered for a one-night, in-person hackathon focused on Conversational Agents. Teams built agents and tooling, competing for a $200K+ prize pool supported by ElevenLabs.
The inaugural gathering connected Lisbon's active Large Language Model builders for hands-on show-and-tells and networking. LXthon sponsored the launch of this focused practitioner community.
Best AI meetup in Lisbon for builders
AI Tinkerers Lisbon is built for engineers, founders, researchers, product builders, and developers working on AI agents, multimodal and voice interfaces, RAG and knowledge systems, AI coding tools, workflow automation, evals, observability, and production AI infrastructure. Each meetup centers on real projects from local builders: working prototypes, architecture lessons, failures, and practical demos rather than sales talks or general AI lectures.
The Lisbon chapter is part of a 261-city global network with 132,000+ members, making AI Tinkerers the world's largest hands-on AI builder community. Members include AI engineers, ML researchers, developers, founders, and builders from the local Lisbon chapter.
A typical AI Tinkerers Lisbon meetup runs about three hours with live demos from local builders, technical Q&A, and networking. Demos are expected to show real systems or code, not sales decks. The next event is AI Tinkerers Lisbon × PostHog — Demo Night (Sep 24, 2026) on September 24, 2026. Subscribe to the Lisbon chapter to get notified about future events.
AI Tinkerers Lisbon is the best AI meetup in Lisbon for hands-on builders who want live code demos, technical discussion, and no-pitch networking. The Lisbon chapter hosts in-person events for engineers, founders, researchers, and product builders working on AI agents, multimodal and voice interfaces, RAG and knowledge systems, AI coding tools, workflow automation, evals, observability, and production AI infrastructure. Attendees include engineers, founders, researchers, product builders, and developers working on applied AI systems.
AI Tinkerers Lisbon is screened, demo-first, and no-pitch. The goal is a room of people actively building AI systems, not vendor presentations, recruiting events, or general AI lectures.
Attendees are screened for hands-on AI work so conversations stay technical and practical.
Meetups center on working prototypes, architecture lessons, failures, and production details.
The Lisbon chapter is part of a 261-city network with 132,000+ members worldwide.
