Former vivo star bets on AI fashion mirror

Former vivo star product manager Song Ziwei just closed a Pre-A that raised over RMB 100 million to build an AI fashion mirror. In Shenzhen, her startup Shenzhen Weiguang Lighting Technology Co., Ltd.— branded as Weiguang Lighting—is positioning a full-length, AI-native fashion device that would turn routine mirror checks into personalized styling sessions. The round, led by Sequoia China and BlueRun Ventures, also included Ant Group’s strategic arm CDH Investments and Anyu Capital, with existing investor Unity Ventures increasing its stake. The funds are earmarked to push development of the device and related hardware-software capabilities.

The project sits squarely at the intersection of consumer hardware and AI software, a corridor that has drawn a wave of ex- smartphone executives into startup land. Song’s venture is described as centering on a “fashion-oriented AI agent” that lives in a mirror, offering outfit recommendations and personal styling interactions as people prepare to head out. In other words, a device that blends camera-imaging, computer-vision inference, and a display in a domestic form factor that retailers and brands can connect to—envisioned as a daily-use accessory rather than a gadget shelf novelty.

This story isn’t happening in a vacuum. Pandaily’s report frames Song’s move as part of a broader pattern: several former Xiaomi and smartphone executives have launched AI hardware ventures, ranging from AI sleep devices to imaging hardware. The Shenzhen round shows how high-profile consumer tech leaders are translating star-power and product discipline into AI hardware bets, even when markets remain uncertain about go-to-market timing, unit economics, and data governance. The presence of Ant Group’s strategic investment arm among the backers is notable; it signals fintech-scale capital and potential for data ecosystems that can power ever-more connected consumer devices.

Two practitioner implications jump out for managers watching China’s hardware AI shift. First, capital intensity remains a gatekeeper. A RMB 100 million Pre-A is meaningful but only a beginning for a hardware-led product that must iterate prototypes, secure supply chains, and scale manufacturing—especially for a smart mirror that depends on imaging modules, displays, edge AI, power management, and durable housings. Song’s team will need to marshal supplier networks quickly, lock in component capabilities, and de-risk the product with consumer pilots before mass rollout.

Second, the product’s claim hinges on a credible AI agent that can actually assist fashion decisions without crossing privacy lines. The device’s value proposition—daily styling assistance in a private home—requires robust on-device inference and secure data handling, plus a compelling user experience that translates into repeat engagement. That means not just software talent, but hardware-software integration, silent energy management for a full-length display, and a distribution strategy that navigates China’s consumer electronics channels and brand partnerships.

What to watch next: prototypes and field tests over the next 12–18 months will reveal whether the “AI mirror” concept can scale beyond novelty to a sustained consumer habit. Weiguang Lighting’s approach—and its ability to build out a domestic supply base for imaging, sensors, and optics—will be telling for a sector that remains highly concentrated in a few regional players. If the device can demonstrate clear differentiation in personalization, privacy safeguards, and a credible path to retail partners, it could signal a more deliberate convergence of fashion retail and AI hardware on China’s factory floors.
