About the event
After four successful editions in 2024—where 19 portfolio companies pitched to more than 150 investors—the o2h ChaiTime Portfolio Pitch Day has firmly established itself as a key platform for early-stage biotechs to connect with strategic investors and partners.
On April 2025, we kicked off the new season of ChaiTime at our Cambridge HQ with another exciting afternoon of science, pitching, and networking. This invite-only event combined five dynamic 10-minute pitches from pioneering biotech companies, a keynote session, and plenty of time to spark conversations over Friday drinks. Our global investor community also joined live via Zoom, keeping the energy international.
The April edition continued the ChaiTime tradition of showcasing breakthroughs, creating connections, and shaping the future of healthcare through collaboration and investment.
This edition’s line-up included:
-
Chris Ullman, CEO at Stratosvir
-
Ciara Doran, CEO at Sansanima
-
Mark Treherne, CEO at Revolver Tx
- Adam Collier, CBO at Spirea
-
Dr Nataly Hastings, CEO at Cellestial Bio
