What GMT does

GMT (上海绿联智能科技股份有限公司 / Shanghai GreenLink Intelligent Technology Co., Ltd.) is a Shanghai-headquartered B2B intelligent home appliance solutions provider founded in August 2011 and listed on China's NEEQ (New Third Board) in January 2016 under ticker 835421. The company designs, develops, manufactures, and sells embedded main control boards, TFT intelligent color screens, and multi-protocol IoT communication modules (WiFi, Bluetooth, Zigbee, PLC, DALI) to major home appliance OEMs, with a stated portfolio covering 74 patents, 59 trademarks, and 42 software copyrights. Its proprietary ProvalleyOS AIoT platform is positioned as a one-stop "cloud + hardware + content operations" stack spanning the "person-car-home" connected scenario, integrating variable-frequency motor control, capacitive/inductive/pressure-sensing touch interfaces, cloud services (data upload/download, remote control, OTA upgrades, manufacturer monitoring backends), mobile APP development for iOS/Android, and big data analytics for connected appliances.

The company operates through two wholly-owned subsidiaries established in 2020: Wuxi GreenLink Intelligent Technology Electronics Co., Ltd. (120+ employees, manufacturing home appliance main control boards with projected 3 million units/year capacity in 2021) and GreenLink (Qingdao) Information Technology Co., Ltd. (40+ employees including 18 technical developers, specializing in smart color screens and sensors). GMT's business model is OEM/embedded B2B supply under quote-based contracts to major domestic appliance brands — Haier, Midea, Yunmi, Hisense — and to international appliance brands including Whirlpool, Electrolux, Panasonic, TCL, Skyworth, Candy, and Blomberg. The company is also a first-authorized partner of the Alibaba IoT "Smart Life Open Platform" (2017) and jointly launched low-cost all-platform communication modules with Alibaba Cloud and 8 chip vendors in 2019.

GMT generates revenue predominantly through hardware sales of embedded control boards, color screens, and IoT modules, supplemented by professional services revenue from APP development, cloud services, and big data analytics. Pricing is contract-based rather than publicly disclosed, consistent with B2B OEM economics. Disclosed external funding is limited to a single round of approximately $2.18M raised in February 2017 from Silan Ventures and Yinxinggu Capital. The leadership team comprises Chairman Bo Li (李波), Operations Director Jianping Zhao, and Technical Director Yeshu Sun.

Direct peers

• Tuya Smart: Tuya is a global AIoT cloud platform serving home appliance, lighting, and IoT OEMs with a very similar 'cloud + hardware + connectivity' one-stop model. It is the most direct competitor to GMT's ProvalleyOS offering and overlaps substantially on customer segments (smart appliance brands) and value proposition (platform-plus-modules).
• MXCHIP (Shanghai MXCHIP Information Technology): MXCHIP designs Wi-Fi/BT IoT modules and embedded connectivity solutions for home appliances and consumer IoT OEMs. It competes head-to-head against GMT's IoT communication module portfolio and serves many of the same appliance OEM customers in China.
• Espressif Systems: Espressif is a Shanghai-based fabless Wi-Fi/BT SoC and module vendor whose ESP series is widely embedded in smart home appliances. While primarily silicon, Espressif competes at the module and connectivity layer for the same OEM design wins that GMT targets with its multi-protocol modules.

Broad incumbents

• Foxconn Industrial Internet (FII): FII is a major global EMS provider offering embedded control boards, IoT modules, and connectivity components at massive scale. It is the dominant incumbent in the broader component supply market for appliance OEMs and represents the scale-and-cost competition GMT faces on volume business.
• Midea Industrial Technology: Midea Industrial Technology is the industrial vertical of Midea Group, producing motors, controllers, and components for HVAC and appliances — and also a current customer of GMT. It acts as both a competitor (vertical integrator) and a customer, representing the strategic dynamics for an OEM-component vendor in this space.
• Qualcomm (IoT & Connected Smart Cities): Qualcomm provides connectivity chipsets, IoT platforms, and reference designs that appliance OEMs can adopt directly, bypassing component-level vendors like GMT. As a broad incumbent in IoT silicon and platforms, it is the upstream threat most likely to commoditize parts of GMT's offering.
• MediaTek: MediaTek supplies Wi-Fi, Bluetooth, and IoT chipsets plus platforms (e.g., Genio, LinkIt) for smart home and appliance OEMs. As a fabless global incumbent, it competes at both the silicon and platform layer with GMT's multi-protocol module and ProvalleyOS stack.
• Quanta Computer: Quanta Computer is a global ODM with significant embedded controller, IoT, and smart appliance capabilities serving international brands. As a broad incumbent it represents the scale of ODM competition GMT would face expanding from Chinese OEMs into Whirlpool/Electrolux/Panasonic-type accounts.

Emerging players

• Hangzhou Landz IoT Technology: An emerging Chinese IoT module and smart-home solutions provider with meaningful overlap on appliance OEM customers and module product offerings. Comparable in stage and positioning to GMT, making it a useful growth-stage benchmark.
• Wulian (Wulian Networks): Wulian is a smart home IoT solutions vendor with cloud, module, and gateway products for appliance and residential automation OEMs. It overlaps with GMT on multi-protocol connectivity and Chinese appliance customer base, but skews more toward complete smart-home system delivery.
