Learn about how organisations are becoming more experimental
Despite the importance of innovation and high-growth entrepreneurship for economic growth, there is still little evidence on how best to create impactful support. We believe that we need a more experimental approach to innovation and growth policy, trialling new instruments but also evaluating them more rigorously. Browse our Trials Database to see what organisations are learning from experimentation!

Our Partners

Innovation Growth Lab is an international initiative led by Nesta in partnership with several public and private organisations around the world.

Our research network

The IGL Research Network includes over 85 researchers from around the world working on randomised controlled trials related to innovation, high-growth entrepreneurship and growth.
