The Emily Tout Story | Mighty Slice


Listen Later

I found today's founder the way I hope more founders find each other... completely by accident. Alice Bugeja, the founder of mileoff, was out on a run when she spotted a woman wearing her gear, ran up to introduce herself, and discovered she was talking to a founder. That founder was Emily Tout, co-founder and CEO of Mighty Slice. Alice even posted a reel about it. And I went down a rabbit hole immediately.

Emily's story is one of the most honest ones I've told on this show. She wanted to be a lawyer since she was eight years old. She went to the London School of Economics, pursued space law, got the career — and then realized it felt completely wrong. What followed was an identity crisis, a brother who was obsessed with entrepreneurship podcasts, a powerlifting habit that rewired how she thought, and a very simple question she couldn't stop asking: why do protein products taste so terrible? Mighty Slice started in her kitchen in 2021. In January 2023 the team was still hand-making every single cheesecake themselves. By the end of that year revenue had grown 1,900%. They're now in Asda, Sainsbury's and Ocado. She's still in it. Still building. And what she said about risk is something I haven't been able to stop thinking about.
