How it started

David Park dropped out of college and, with co-founder Henry, went through nine or ten failed startups before experimenting with GPT-2 and creating Jenni. Henry coded while David cold-called agencies from his parents' house; revenue plateaued at $2K/month until they talked deeply to users and rebuilt the product. A viral Twitter thread took them from $2K to $10K MRR in a month, and viral TikTok/Instagram content drove further waves of growth despite David's cancer diagnosis.
