Value proposition
Vobiz.ai is an API-driven, AI-native telecom stack that replaces legacy CPaaS systems with low-latency (<80ms), developer-friendly telephony infrastructure optimized for real-time AI voice agents, with instant provisioning, TRAI compliance, and Indian-market focus.
Products and solutions
SIP Trunking; Voice API; Programmable Telephony; WebRTC; Instant DID (Phone Number) Provisioning; AI Voice Agent Infrastructure (WebSocket audio streaming, real-time bidirectional audio); Noise Cancellation; Compliance Automation (TRAI/DLT); LLM-friendly APIs; Integrations with Vapi, Retell AI, ElevenLabs, LiveKit, Pipecat, OpenAI Realtime, Ultravox, Bolna
Unique value
Only Indian-market telephony API with native support for the full ecosystem of AI voice agent platforms — Indian DID numbers, INR billing, TRAI compliance, sub-80ms latency, and 99.99% uptime, purpose-built for AI workloads rather than adapted from human call center infrastructure.
Target customer
Enterprises in regulated industries (BFSI, healthcare, logistics), AI voice agent developers, CPaaS platform builders, and contact center operators in India
Industries served
BFSI (Banking, Financial Services & Insurance), Healthcare, Logistics, Real Estate, Collections/NBFC, E-commerce
Technology advantage
Single-hop, event-driven architecture with direct carrier interconnects; average end-to-end latency under 80ms (vs 400-600ms for legacy); WebSocket-based bidirectional audio streaming for AI agents; instant self-serve provisioning (no weeks of paperwork); built for AI-native features like barge-in, dynamic context switching, and mid-call updates; supports 1M+ calls/day scale
How they differentiate
Unlike Twilio, Exotel, and Plivo which were built for human call centers and BPO-era telephony, Vobiz is architected from the ground up for AI voice agents — with sub-80ms latency, WebSocket streaming for AI pipelines, instant self-serve provisioning (vs weeks of paperwork), and native TRAI compliance. It is the only Indian-market telephony API with native support for the full AI voice agent ecosystem (Vapi, Retell, ElevenLabs, etc.) and offers INR billing.

Major milestones
Founded late 2025 (official launch ~Nov 2025); Pivoted from Posibl.ai (AI voice agent builder) to Vobiz.ai (AI-native telephony infrastructure); Raised $1M seed led by Piper Serica (May 2026); Crossed 5,000 signups and 1M+ calls/day
Growth metrics
5,000+ signups; 80%+ month-on-month growth; scaled from 100,000 calls/week to 1M+ calls/day; targeting $5M ARR by end of FY27
Market positioning
India-first, AI-native CPaaS challenger positioning as the "Stripe for telephony" — targeting the gap between legacy CPaaS providers (Twilio, Exotel, Plivo) and the exploding demand for AI voice agent infrastructure in regulated Indian enterprises.
Geographic focus
India (primary), with architecture designed for global scalability
