Lightin

Lightin (光粒科技) is a Chinese smart sports eyewear brand that has evolved from a single smart-swimming-goggle product into a multi-scenario portfolio covering swimming, running, and other activities. Linear Capital, which led its angel round as the sole investor and has since added follow-on checks, introduced it in early 2022 as a maker of consumer AR glasses under the Lightin Me line with an interaction module called HandPlus . By March 2026 the company had raised nearly RMB 100 million in a Pre-B round to fund team expansion, R&D, and global marketing; its products were already stocked in Decathlon stores as well as professional eyewear retailers like Wu Liang Cai and Gozem . The brand is also known by its Chinese tagline "光粒科技" (Lightelligence in some English renderings).
