What Teo Hong Silom does

Teo Hong Silom is a privately held Thai conglomerate founded in 1974 by Mr. Phaisan Sirirat-usdorn, headquartered in Samutprakarn with offices in Bangkok's Silom business district. The group operates across four primary business sectors: Information and Communications Technology (ICT) system integration, Medical Equipment distribution, Special Products (acting as exclusive Thailand distributor for Noritake tableware), and Property Development. Within ICT, the company delivers telecom network infrastructure (DWDM, MPLS, FTTX, 4G/5G), IoT/LoRaWAN, smart building automation, CDN/DPI, anti-DDoS, IPTV/OTT, RPA, data analytics, and AI-enabled customer support. Medical Equipment distribution covers ATOM Medical neonatal incubators, Philips UV-C/UVGI disinfection systems, neurosurgical instruments, EEG equipment, and EcoMed antimicrobial disposable curtains featuring Microban technology. Property Development includes Garden Towers luxury apartments, Bangna Pride Hotel & Residence, Bangna Convention Center, and commercial/residential leasing operations.

The group operates a multi-subsidiary structure under holding entity THS Growth Co., Ltd. (established 2005, restructured 2017), including THS Development (M&E installation), THS Innovations (registered ESCO for chiller and air-compressor efficiency), THS Parking Solutions (automated parking systems), THS Soft (IoT, data analytics, RPA software development since 2019), Prompt Techno Service (facility management O&M/FMS/TFM since 1992), MATTHA Company Limited (building materials), THS Wellness, and the Evercomm Thailand joint venture delivering carbon accounting (ISO 14064 / GHG Protocol compliant) and solar solutions. Revenue derives primarily from hardware sales (telecom equipment, medical devices, tableware, building materials), professional services (engineering, facility management), and managed services (energy performance contracts, carbon platforms), with project-based quotations rather than published pricing. Go-to-market is consultative, direct enterprise sales supported by dedicated sales teams per division, an ICT headquarters on Silom Road, and a regional service office in Songkhla; the company holds ISO 9001:2015 and ISO/IEC 27001:2022 certifications, and Evercomm Thailand is B Corp certified.
