What Season Group does

Season Group is a privately held, family-owned Electronics Manufacturing Services (EMS) provider founded in 1975 in Hong Kong by Patrick Hung and now led by CEO Carl Hung. The company operates an integrated design-and-manufacturing platform spanning Design-for-Manufacturability (DFM), PCBA production, wire harness and cable assembly, plastic injection molding, box build, supply chain management, and wireless connectivity integration through its subsidiary SG Wireless Limited. Manufacturing is distributed across four certified sites in Dongguan (China), Penang (Malaysia), Havant (United Kingdom), and Reynosa (Mexico), with the Reynosa facility expanding to 82,000 sq.ft. and a new 43,594 sq.ft. office building under construction in Dongguan. The company holds AS9100 certifications across three sites and IATF 16949 at Reynosa, qualifying it to serve aerospace, defense, and automotive OEMs.

The company serves enterprise customers across six primary verticals: Industrial Electronics, Security, Power Electronics, Automotive, Healthcare, and Aerospace & Defense. In December 2022, Season Group acquired the assets of Pycom Ltd, a UK-based IoT technology company that had entered administration, establishing Pycom BV in the Netherlands as an autonomous subsidiary. The Pycom acquisition added a full-stack IoT platform including PyBytes Device Cloud, supporting Wi-Fi, BLE, LoRaWAN, and LTE-M connectivity protocols, and brought 200,000+ enterprise customers across 120+ countries and an 800,000+ developer community. Season Group monetizes through three revenue streams: EMS manufacturing services (hardware sales), design engineering services (professional services including DFM, IoT design, and wireless design), and supply chain solutions (managed services including component sourcing, logistics, and VAVE).

Go-to-market is direct enterprise sales with global business development teams and executive leadership engagement. The company quotes on a per-project basis tailored to product complexity, volume, and manufacturing location, with multi-year contracts. Headcount stands at 1,500-1,800 employees worldwide across five locations on three continents. In January 2026, the company announced a brand refresh positioning itself as an integrated design-engineering, wireless, and global manufacturing partner for connected, resilient products.
