UK & Europe Program

Scaling impact across the UK & Europe

Launched in 2016, we are now in our 8th year of supporting growth-stage ventures operating at the nexus of advanced technology, profit and impact.

To date, alongside our partners at Barclays, we have supported 87 ventures headquartered across the UK & Europe that are uniquely positioned to create the jobs of tomorrow, while solving our most pressing societal and environmental challenges. The UK & Europe programme is part of Unreasonable Impact's broader global initiative that is actively supporting 310+ ventures.

Meet our UK & Europe Cohorts

Each year we identify and privately invite a select portfolio of growth-stage ventures to join the Unreasonable Impact UK & Europe program.

This cohort is supported by a curated community of Unreasonable mentors, investors, and Barclays' colleagues. Together this community of support is dedicated to championing the growth and impact of the ventures now and into the future.
