Kaon (prev. FlowGPT)
Kaon (formerly FlowGPT) is a San Francisco AI-native content lab building consumer AI experiences. After scaling FlowGPT into a 4M+ monthly user prompt marketplace, the team shifted gravity to Emochi - an AI character roleplay app that has climbed into the top tier of consumer AI with millions of monthly users. Founded in 2023 by UC Berkeley dropout Jay Dang and co-founder Lifan Wang, the company raised $10M led by Goodwater Capital and DCM in early 2024 and added a strategic round backed by B Capital and Redpoint in 2025.
Jay Dang
Jay Dang (Jiacheng Dang) is the co-founder and CEO of Kaon (formerly FlowGPT), an AI-native content platform he launched in January 2023 just two days after founding the company - at age 20 during his freshman year at UC Berkeley. He subsequently dropped out to lead FlowGPT full-time, growing the platform to 3+ million monthly active users and 100,000+ AI applications across 110 countries before raising a $10M pre-Series A round in February 2024 led by Goodwater Capital and DCM Ventures. Under his leadership, the company rebranded to Kaon and launched Emochi, an AI storytelling app that reached #12 globally with 12.3M monthly active users by April 2026.
