Gyges Labs is an AI hardware startup behind Halliday, smart glasses that pioneered an invisible, all-day-wearable micro-display projected directly into the wearer's field of view via a module Gyges calls DigiWindow. Unveiled at CES 2025 and priced around $489, Halliday positions itself as the world's first proactive AI glasses, surfacing real-time translation, transcription, teleprompting, navigation and assistant responses without an obtrusive screen or outward camera. The Halliday Kickstarter became the largest AI-glasses crowdfunding campaign in history, with more than 8,000 backers pledging over $3.3 million, and the company began shipping units in 2025. Gyges Labs is the first AI hardware investment by prominent investor Zhu Xiaohu and has raised multiple venture rounds, including a Pre-A round of tens of millions of RMB led by GSR Ventures with Shokz founder Chen Hao and NYX Ventures, plus a Pre-A+ round backed by Granite Asia and Bright Capital.
