The Idea: In 2017, Victor Riparbelli was a sci-fi obsessed kid from Copenhagen who stumbled across a research paper called "Face-to-Face" that could make anyone appear to say anything on video. It felt like magic - the kind of technology he'd only seen in movies. Victor had no AI PhD, no Google credentials, and no Silicon Valley connections. But he knew this tech would change everything. He cold-emailed the researchers behind the paper - Matthias Niessner from Stanford and Lourdes Agapito from UCL - and convinced them to join forces. Together with Steffen Tjerrild handling operations, they set out to build the world's first AI video platform. The only problem? Every VC in Europe said no. After roughly 100 rejections, Victor took a shot in the dark and emailed Mark Cuban. Cuban wired $1 million overnight. This was the beginning of Synthesia.
The Execution:
The lesson? Victor spent months trying to convince skeptical European VCs that AI video was the future. They all said no. Then one email to Mark Cuban changed everything. The lesson isn't about persistence - it's about finding the right audience. Stop trying to convince skeptics. Find the missionaries who already believe in what you're building.
