Now in its third edition, the HackSummit has become an annual highlight for Europe’s impact-driven founders and funders.

In just 4 month’s time, 1500 of the brightest minds in Climate will head to the lakeside city of Lausanne, Switzerland for a full week of jam-packed action, deal-making and events centered around the HackSummit on June 13-14th.

The expectations are high. The 2024 edition has already been tipped by Sifted as a top tech event and by Climate Insiders as a must-attend Climate event.

So to deliver a world-leading Summit, we’re scouring the globe to curate a speaker line up of the most cutting-edge founders, active investors and seasoned experts to join us for panel debates, intimate fireside chats and inspiring keynotes.

Without further ado, it’s time to meet the first confirmed speakers taking to the stage:
