Please join us from Friday, 14 March to Saturday, 15 March 2025 for the Unreasonable Impact UK & Europe Exclusive Forum, held at the beautiful Tewinbury Farm Hotel in Hertfordshire UK.

Throughout the event, you will meet leaders of growth-stage ventures that were handpicked for their promise of addressing key environmental issues while creating the jobs of tomorrow.

As a guest, you will have the opportunity to immerse yourself in our cohort of innovators of scalable and impactful businesses while experiencing the unique vibrance of an Unreasonable-run program. You will be amongst a group of leaders from top-tier venture funds, private equity institutions, family offices, and foundations who were selected to meet our entrepreneurs in an intimate and relaxed setting.

We invite you to join us on Friday, 14 March at 11:00am, providing you with time to settle in and connect with the entrepreneurs and other guests before official programming begins at noon.

The main gathering on Friday includes an afternoon of meeting and learning about our cohort of ventures and will continue through the evening with a drinks reception and dinner. We also invite you to stay the night at Tewinbury Farm Hotel (as our guest, including breakfast & lunch), giving you the opportunity to join Fireside Chats after dinner to hear the stories of our brilliant entrepreneurs and enjoy additional networking with the community. The event finishes on Saturday, 15 March at 2:00pm after lunch.

This event is by invitation only. Please see the FAQs below, and if you have any further questions, please email Muzna Khan at [email protected].
