Undaunted’s flagship accelerator programme
The Greenhouse
Demo Day is Undaunted’s flagship event. Our climate innovation community comes together to celebrate the latest cohort as they graduate from The Greenhouse accelerator, pouring what they’ve learnt over the past 12 months into impressive pitches to investors.
Watch each Cohort 7 Demo Day pitch
Our most recent Demo Day took place on 8 May 2025. Cohort 7 of The Greenhouse took to the historic stage at The Royal Institution to pitch to investors and Imperial’s climate innovation community. Each founder had just five minutes to pitch, and five minutes of Q&As, and it was afternoon jam packed with passionate presentations and intelligent solutions to tackle climate change.
