DON'T MISS OUT!

Why should you attend Lambda Days? (a.k.a. "why can’t I just watch the talk videos online for free instead…?")

Firstly, the videos will be kept exclusive to the attendees for some time.

But mostly: because of the people! The greatest asset of any conference is the community behind it. The Lambda Days crowd is inquisitive, open-minded, friendly and known to motivate each other to learn and innovate.

They ask the right questions, recommend the best talks, point to concepts to explore, inspire and challenge preconceptions at every turn.

Want to make the most of the content our speakers prepare? Experience it live with a crowd of people as excited about it as you are!
