LangCore

LangCore (语核科技) is a Chinese AI startup focused on B2B applications, founded and led by CEO Xingji Zhai (翟星吉) . The company has positioned itself around a disciplined, product-first approach to enterprise AI: Zhai's stated philosophy is "not doing what, is more important than doing what" — meaning strategic restraint in choosing which problems to solve .

In 十字路口Crossing's coverage, Zhai has discussed the survival rules for B2B AI entrepreneurs, framing LangCore's work around cutting into enterprises' core business operations rather than peripheral use cases . The company was cited as having achieved notable commercial results — in one 十字路口Crossing interview from mid-2025, Zhai was described as an AI-to-B entrepreneur who "didn't touch a drop of Moutai and still did 30 million last year," suggesting annual revenue in the tens of millions of RMB .

LangCore appears primarily in 十字路口Crossing's "AI in China" series and related roundtables as one of the emerging, operationally-focused AI startups navigating the competitive Chinese enterprise market . The company's technical stack or specific product details are not covered in elsewhere's current corpus.
