Synthesia founder on timing: young founders should chase non-consensus ideas early

synthesiaIO · x · 2026-10-21

Synthesia CEO Victor Riparbelli founded the company in London in 2017, when Hollywood-quality video from a laptop sounded impossible; it grew fast from 2020, about 1.5 years before ChatGPT. His advice on timing:

Riparbelli was 25 at founding; being "young and naive" let the team believe in an idea outside consensus.

The reposter also launched GR Angel with a partner: portfolio companies have raised $1.2B+ (Replit, HappyRobot, etc.), co-investing alongside a16z, Sequoia, Founders Fund and General Catalyst, with one exit scaling from $10K MRR to $7M ARR in under a year.
