On November 9, ThunderPhone launched v3 with Zeus, which it calls a fully agentic harness for voice AI. Zeus can create a voice agent from a conversation about your business, or from call-center recordings, scripts, and SOPs. It can also import an existing agent from Vapi, Retell, Bland, or ElevenLabs. It then connects VoIP and software integrations, runs text and audio call simulations, flags problems on live calls, and proposes A/B tests of fixes. You choose whether it asks before each change. v3 retires the Spark, Bolt, and Storm stacks for one architecture that Zeus tunes per use case. Zeus can optimize toward a hard price cap or toward conversion value minus call cost. Zeus is free for now. Calls use cost-plus pricing with a 17% to 25% margin, and US numbers are $1/month each.
