Xingji Zhai

Xingji Zhai is the founder and CEO of LangCore (语核科技), an AI-to-B startup that had raised a seed round led by MiraclePlus as of mid-2025 and was then in talks for its next round . He has been a recurring voice in 十字路口Crossing's coverage of AI entrepreneurship, where he has framed his operating philosophy around disciplined focus—"not doing what, is more important than doing what"—as a survival rule for B2B founders navigating the AI hype cycle . In one 十字路口Crossing panel, he described hitting roughly RMB 30 million in annual revenue without relying on the traditional Moutai-fueled enterprise sales culture . The name "Xingji" (星吉) appears to be a partial match with "Xingji Guangnian" (星吉光年), though the bundle does not clarify whether this is the same entity or a naming coincidence .
