Climate X Deep Tech
May 15-16, Lausanne
At HackSummit, we bet on the bold.
That’s why we’re doubling down on Climate Deep Tech at this year’s summit—supporting companies at the cutting edge of hardware and science-driven solutions.
Meet the Next Generation of Scientist-Leaders: CSOs and CTOs are the new rockstars, leading the charge in developing transformative technologies for climate solutions.
Explore the Climate Science Fair: Where early-to-growth-stage climate deep tech startups showcase their frontier technologies and connect with investors and industry leaders.
Make Real-World Impact: Engage with pioneers who are turning ambitious ideas—like fuels from CO2 and cloud seeding—into tangible solutions.
