This selection of large companies in Shenzhen primarily features major players in telecommunications and technology. Huawei, a global provider of ICT infrastructure, and Tencent, a technology company known for social platforms and financial services, are prominent. Other significant entities include OPPO, a leader in smart device innovation, and PING AN, a financial services group with a focus on intelligent ecosystems. These companies generally represent well-established, large-scale operations.
A notable pattern among these companies is their strong concentration in the technology and telecommunications sectors. Several, such as ZTE Corporation, specializing in telecommunications and IT, and Transsion, focusing on smart mobile devices for emerging markets, highlight this trend. The presence of companies like BYD, involved in IT, automobile, and new energy, also indicates a diversification within the broader tech industry.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
