The openingWhy this idea is overlooked
Many teams do not want a closed end-to-end voice platform; they want composable infrastructure they can self-host, orchestrate, and control, mixing their own ASR, language models, and telephony. Serving those developers with an orchestration framework, low-latency pipeline, and self-hosting options is a distinct business from an enterprise platform. It rides the same voice-AI wave from the picks-and-shovels side, where control and flexibility are the selling points.
