# HaloVoice
HaloVoice is the all-in-one AI voice agent platform for businesses. Build voice agents and chatbots that handle inbound calls, run outbound campaigns, qualify leads, answer questions from your documents, book meetings via Cal.com, and run on WhatsApp — 24/7 in 30+ languages, no code required. Headquartered under S2 Data Systems with offices in Newark, Delaware (USA) and Pune, India, HaloVoice combines voice AI (OpenAI, Cartesia, Sarvam AI), reasoning models (OpenAI, Google Gemini), Twilio and Vobiz telephony, Pinecone vector retrieval, Stripe billing, and a complete operations layer (smart agents, visual flow builder, multi-agent workflow interpreter, lead routing, nurture engine, embeddable forms, real-time analytics, DNC compliance, AI decision audit) into a single self-serve product.
The platform is purpose-built so a non-technical operator can ship a working voice agent in under an hour. Where voice API toolkits leave the operations layer for you to build, HaloVoice ships it pre-built — campaigns, leads, knowledge base, compliance, audit, and team controls all live in one product. Plans start at $349/month with 2,000 included minutes; per-minute rates from $0.12 to $0.22 depending on tier. BYOK supported on every provider on every plan.
