Rasmus Sanne’s path began on the basketball court, representing Sweden’s national youth team and moving to the Arctic Circle at sixteen to pursue a pro career. After injuries ended that journey, he shifted his competitive drive to academics at the Stockholm School of Economics, coaching basketball on the side and becoming Sweden’s youngest youth national team coach at 23.

At university, he co-founded his first startup with two teammates. What started as a tutoring app pivoted into an IT-consulting model that taught students the skills companies actually needed. Their TikTok storytelling grew to 200,000 followers and sparked demand for an online education platform helping adults learn programming while working full-time.

Frustrated by the limits of paid social advertising, Rasmus entered Lovable’s global AI hackathon in 2025. Out of 2,000 teams, they won — leading to the creation of Stardust. The team pre-sold the product to €100k ARR before writing any code and later raised €1.7M in pre-seed funding to build a new marketing category: Evolution Marketing, a self-learning intelligence that helps brands understand why their ads work.
