What Plexus does
Plexus is a privately held South African business technology provider founded in 1998 and headquartered at 114 Waterhouse Road, Benoni North AH, Benoni. The company operates four integrated business divisions: telecommunications (anchored by its proprietary Plexsmart cloud-hosted PBX and VoIP platform, including call center solutions and mobility services), IT services (managed IT, cybersecurity, network infrastructure, and cloud migration/management), office automation (printers, CCTV, and time-and-attendance systems), and solar energy (through its Plexus Power sub-brand, which supplies residential, commercial, and industrial PV systems with battery storage using GoodWe inverters). The business serves a mix of South African enterprises, mid-market firms, and homeowners, addressing communication reliability, cybersecurity, and energy resilience needs, with load shedding being a notable demand driver for the solar offering.
The company's revenue model combines non-recurring hardware sales (printers, CCTV equipment, solar panels, inverters, and battery storage) with recurring revenue from hosted PBX subscriptions, managed IT and cybersecurity services, and professionally installed maintenance contracts. Pricing is not publicly disclosed and is provided on a quote basis; the company also offers Self-Finance Solutions that bundle equipment with maintenance and insurance, effectively smoothing upfront acquisition costs for customers. Go-to-market is sales-led and direct, primarily through website contact forms, email ([email protected]), phone (011 823 4800), WhatsApp, and a national network of offices and service centers across South Africa's major metropolitan regions.
The technology stack centers on the Plexsmart communications platform and a multi-vendor partner ecosystem that includes GoodWe (solar), Fortinet (cybersecurity), Mikrotik, Snom, Vox, Hikvision, MTN, Vodacom, Reyee, Comsol, Liquid, and Amatola. Operations are supported by a small team (11-50 employees), and the company is privately held with no disclosed parent, institutional investors, or public listing. Certifications, regulatory credentials, and quantified revenue figures are not present in the available data.
