I let an AI cold-call 100 plumbers to sell them a 24/7 AI receptionist. My Stripe started at $0. I built this whole thing using Genspark by orchestrating 6 different AI agents from a single prompt: a research agent, an AI developer, a Stripe agent, a voice script agent, a call-for-me agent, and an AI inbox agent. The whole stack built itself, ran 100 live cold calls, and converted 4 plumbers to paid sign-ups in 1 hour. Here is exactly how it worked.
