刘斌新
Binson Liu (刘斌新) is the founder of LynkSoul (心影随形), the company behind the AI companion product Doudou AI, which he started in 2023 after a classic big-tech career — CS-trained, with stints as an assistant president at Qihoo 360 and deputy director at Baidu, and most recently vice president at Bilibili, his first venture into entrepreneurship . His product thesis is deliberately contrarian: rather than competing with short video and games for user time, Doudou AI is a desktop-pet-style companion that requires no extra time investment — a form he defined by saying no to the Character.AI route everyone else was copying . The bet appears to have landed: per a Source Code Capital piece, the product gained 1 million users in its first 10 days after launch . Angel investor Xiao Wang has cited that willingness to reject the crowded overseas playbook as a key reason he backed Liu .
