About Lisbon · September 2026
September brings Lisbon's best AI builder stretch before Web Summit swallows the city in November. Cerebras hosts a Cafe Compute session on Sep 10, Lenny's Newsletter meets Sep 14, and Lisbon AI Week opens Sep 21 for a week of AI-track content. Web Summit arrives Nov 9, 70,000 attendees and a concentration of VC capital that makes most other conferences look sparse. Portugal Tech Week and a Female Founders Breakfast both run that same week.
