Featured in Forbes 30 Under 30 in 2025

"Danish clothing brand Boom Butik was founded during Covid-19 lockdown by Viggo Ebbesen Rungø when the world was hungry for sweatpants for staying at home. He initially started delivering the clothes himself on his bike around Copenhagen. [...]

The company has expanded to brick and mortar with a store in Copenhagen and another opening in Stockholm. The brand brought in revenue of $8.4 million in 2024, which it expects to exceed in 2025."
