Pieter Muller is the founder of FlowLeads, a Durban-based home-services quote platform for South Africa. A software engineer by background, he built FlowLeads to give SA homeowners honest, data-backed matches with verified local professionals — across solar, plumbing, electrical, security installation and the trades that follow. Every niche on the platform is gated to its statutory regulator (SAPVIA, IPSASA, the DEL Wireman register, PSiRA), so homeowners only ever talk to legally compliant partners.
