Designed for real conversations. SigmaMind AI is a Voice AI platform for developers and enterprise teams to build, test, and deploy human-like AI agents.Our goal? Help you launch outcome-driven agents that don’t just respond - they act.Founding story: Why we startedWe started SigmaMind AI after working in high-scale environments and seeing the same thing over and over again:Customer support was overwhelmed. Sales teams were too slow. Call centers were stitched together with tools that didn’t talk to each other. Everyone wanted automation, but no one wanted to build it from scratch.So we did.We built SigmaMind AI - a platform where developers, consultants, and enterprise teams can launch AI agents that don’t just talk - they act. Agents that resolve support tickets. Book appointments. Follow up on leads. Even handle collections.And they work across every channel - voice, chat, and email.You can plug in your data, define behavior, connect to real apps like Shopify or Zendesk - and launch. No fine-tuning, no hosting. Just output that works.Today, developers use SigmaMind AI to build for clients. IT firms resell it. BPOs scale with it. And enterprises run real conversations - with measurable outcomes, not just fancy demos.Our teams are based out of San Francisco (USA) and Bengaluru (India).SigmaMind AI's FoundersAshish AgarwalCo-founderPratik MundraCo-founderTrusted byReady to build, launch, and scale your AI agent?Try for freeContact Sales --- { "@context": "https://schema.org", "@type": "Product", "name": "SigmaMind Voice AI Agent Builder", "brand": "SigmaMind AI", "description": "Build production-ready voice AI agents with real-time reasoning, tool calls, and call transfer capabilities." } Powerful Agent Builder for Voice AISigmaMind’s Agent Builder lets developers and enterprise teams build production-ready Voice AI agents using a single prompt.
