Dom is one of two co-founders behind Runna, the world’s top-rated personalized running coaching app. Launched in 2021, the app is now used by hundreds of thousands of runners from more than 180 countries. Runna incorporates advanced technology combined with real-world running and strength and conditioning plans and workouts from top running coaches to personalize each user’s experience based on their ability, goals and schedule.

"Honestly, making the Forbes 30 Under 30 list has been a dream for as long as I can remember,” Dom says. “When I left McKinsey to start Runna three years ago, I had no idea we'd ever make it to market, let alone reach this point. We definitely couldn't have done it without our first team members who also quit their jobs and took big pay cuts to join us from the start.”

Dom says he has three goals for the next year: “Continuing to work with and grow our incredible team in London; continuing to build the world's #1 running training app – we have so many features that we'll be releasing this year! – and expanding to the U.S."

Heiner is the co-founder of Throne, a leading gifting platform for creators. More than 500,000 creators from nearly 90 countries use Throne's all-in-one wishlist builder to let their fans support them in a way that protects their privacy.

“To be featured on the Forbes 30 under 30 list is definitively a great recognition for the last ten years of work,” Heiner says. “I am deeply grateful for everyone who helped me along the way.”
