Rockstar🎓
Top SchoolAnthony Minessale is a veteran software engineer and serial founder with 25+ years building telecommunications and open-source systems, best known for founding FreeSWITCH and the ClueCon conference in 2005 and launching SignalWire in 2017. As Founder and CEO he blends deep protocol-level expertise (hands-on work in Sofia-SIP and FreeSWITCH back-end modules) with product leadership to commercialize programmable unified communications and AI-driven call fabrics. His career spans startup CTO roles to directing engineering at Barracuda CudaTEL, consistently shipping scalable, production-grade voice, video, and messaging platforms. Based in Brookfield, Wisconsin, he pairs systems-level engineering (fixing SIP session, TLS, WebSocket, and media issues) with an entrepreneur’s instinct for product-market fit. Less obvious: he has repeatedly converted open-source technology into sustainable businesses and events that galvanize the global telephony developer community.
