XL Day 2026 is HighTechXL’s Demo Day, where our entire deep-tech community comes together. Founders, investors, industry leaders, and partners gather for an exclusive deep-tech showcase and a day of meaningful connections.

During the event, you’ll hear the latest updates from HighTechXL and meet the newest ventures in our program as they take the stage for the first time, sharing the technologies they are building and the impact they aim to create.

Alongside the main stage, breakout sessions will explore topics such as building a Startup Factory for the Netherlands and Europe, collaboration around security and defense, and an exciting Investor’s Arena, where several ventures will pitch to investors.

The full program will be announced soon. Register now to secure your spot and stay in the loop as we reveal more.

See you at XL Day 2026.
