Many successful businesspeople create one company and spend their lives scaling it, but for others, one just simply isn’t enough.

As these entrepreneurs progress through their careers, they spot new industries that are worth branching into, take time to pursue what they’re really passionate about, or sometimes, for whatever reason, they just don’t get it right the first time. For our latest top 32 list, we took a closer look at serial founders.

How was the top 32 chosen?

We asked our audience to suggest exceptional founders who have not only founded and scaled multiple companies but have left a mark on their respective industries. The founders included on this list are based in the UK and have either founded or co-founded at least two companies.

This list is in no particular order.
