By invitation. 

You’ll be guided through the festival, and will get to explore the festival campus, with climate-tech product demonstrations, future-food tastings, bespoke networking opportunities, and more. Full details to follow in the coming weeks. 

A lively, informed, engaging and tightly curated session of 10-minute keynote talks, from key figures in climate-tech. Full details to follow in the coming weeks on our Speakers page. 

Your ticket will include a lunch voucher, for a nutritious and tasty vegetarian picnic lunch. But we want you to make new friends, so we’ll redeem vouchers only when presented in groups of at least 4 (which means you’ll get to meet fellow THE HEAT participants!)

THE HEAT’s “unconference” sessions are driven entirely by you: over two hours, participants run sessions that they’ve proposed, including workshops, discussions, talks, science demos, or whatever you’re excited by. This is our “open-source” part of the day, tapping into the knowledge, creativity and thoughtfulness of the crowd. In the morning, you can propose your session with a marker pen on a whiteboard which is divided into 50-minute slots in 8 locations on the festival site. You can then pitch for an audience from the main stage before lunch. Surprise us!
