Lambda Days 2025

Lambda Days is an event like no other gathering people passionate about functional programming. The first year, in 2014, was an amazing surprise - an explosion of inspiration and positive energy generated by local communities of tech experts, students, specialists, leaders and innovators. Second edition of our conference exceeded all expectations - with almost 400 attendees, 47 speakers and 7 tracks over two days it was hard to decide which opportunity deserves most attention. Since then we're the biggest functional programming conference in Europe.
