Xingyuan Yuan
袁行远
Xingyuan Yuan is the founder and CEO of ColorfulClouds (彩云科技), the Beijing AI company behind the Caiyun weather app and the AI writing product Dreamily (彩云小梦), launched in 2021 . Per a 5Y Capital Tavern interview, he leaned on machine-translation work with China Literature starting in 2019, which got him re-reading web novels — the thread that led to Dreamily . He took 5Y Capital's A-round money over a competing strategic investor, recalling that Fisher (Fei Zhang) told him 5Y would "support you doing what you love" ; he was still presenting as founder-CEO at a Unity Ventures salon as of early 2025 . A darker moment surfaces in the same 5Y conversation: after one board meeting during a Beijing smog winter, he and CTO Xu Tao talked until 2 a.m. about how to rescue the company by bringing in more advertisers .
