Company profile
researched Aug 2026Plivo operates an enterprise customer engagement platform structured in three layers: a cloud-based carrier network at the infrastructure level (SIP trunking and phone numbers) providing connectivity to more than 190 countries; an API suite that lets web and mobile applications integrate messaging (SMS, WhatsApp, RCS) and voice (voice calls, WhatsApp calls) programmatically; and, at the application layer, an AI Agent Platform for building agents that handle customer interactions [3]. The company states it powers billions of interactions per month and serves 1B+ API requests monthly [3].
The current product focus is voice AI agents. Plivo offers two build paths: a programmable route in which developers connect LiveKit or Pipecat agent frameworks, or build directly on Plivo voice APIs, using SIP trunking and bidirectional audio streaming with noise cancellation and SDKs for Python, Node, Go and REST; and a no-code "studio" where agents are described in plain English and assembled visually for omni-channel deployment [0]. Advertised platform characteristics include sub-500ms voice latency, 99.99% uptime, 50+ languages, 30+ accents, interruption/turn detection, and automated simulation, evaluation and observability tooling [0]. Common agent use cases cited are sales, lead qualification, order tracking, payment collection, feedback surveys and identity verification [0].
Plivo lists HIPAA, GDPR, SOC 2, PCI DSS and STAR compliance, TLS in transit and AES-256 at rest encryption, selectable US/EU/APAC data residency, and access logs, RBAC and compliance reporting [0]. Y Combinator's profile describes Plivo as serving thousands of businesses and names Uber, Meta, Zomato and GoDaddy as customers [4].
Business model
Plivo sells communications infrastructure and AI agent software directly to businesses on a usage-priced, self-serve plus enterprise-sales model. A pay-as-you-go tier covers the United States and India with SIP trunking, audio streaming, AI agents and phone numbers, capped at 2 RPS, 50 concurrent calls and $2,500 of monthly usage. An enterprise plan starting at $1,000 per month adds coverage across 190+ countries, SMS, WhatsApp and Verify APIs, shortcodes and custom sender IDs, custom/volume pricing and compliance features such as BAA, HIPAA and SSO [2]. The about page states the company has been profitable since 2015 [3].
Consumption-based pricing per minute and per message, layered with a minimum-commitment enterprise subscription. Telephony is billed separately from AI agent usage: outbound calls start at $0.0010/min and inbound at $0.0028/min, voice AI agents cost $0.03/min covering voice models, transcription and orchestration, SMS starts at $0.0077 per message, and WhatsApp messages start at $0.0037 with WhatsApp calls at $0.0040/min. Enterprise plans start at $1,000 per month; new users receive $10 in free credits without a credit card [2].
Traction
Public indicators are largely company-reported: 1B+ API requests per month, 190+ countries served, and profitability since 2015 [3]; a live counter of minutes of customer conversations handled by AI agents, 99.99% uptime and 150+ countries connected on the homepage [0]. Y Combinator states Plivo powers billions of transactions each year for thousands of businesses including Uber, Meta, Zomato and GoDaddy, with a team size of 320 [4]. The about page describes a 100+ person team across two countries [3], while a third-party Austin directory lists 51-200 employees [5].
Latest developments
Plivo's current positioning centers on voice AI agents, offered through a no-code agent studio and programmable APIs that integrate with LiveKit and Pipecat, priced at $0.03/min excluding telephony, alongside a pay-as-you-go tier with $10 in free credits and an enterprise plan starting at $1,000/month [0][2].

Market position
Plivo positions itself as a communications platform provider that merges AI with enterprise-grade telecom infrastructure, spanning the carrier network, API layer and AI agent applications [3]. It cites scale indicators including 1B+ API requests per month, 190+ countries served, 99.99% platform uptime and named large customers [3][0][4], and differentiates commercially on transparent per-minute pricing and profitability since 2015 [0][3].
Plivo emphasizes owning the underlying carrier network rather than reselling, letting it offer self-serve carrier-grade trunks, real phone numbers and one-hop routing beneath its AI agents, with telephony and agent costs priced transparently and separately [0][2][3]. It also supports both no-code agent building and bring-your-own-framework development (LiveKit, Pipecat) on the same telephony layer, and markets human-likeness attributes such as sub-500ms latency, noise cancellation, turn detection and self-improving evaluation loops [0].
Technology
The stack combines a carrier-grade telephony network with real-time voice AI. Infrastructure includes SIP trunking, phone numbers and bidirectional audio streaming with noise cancellation; interfaces include messaging (SMS, WhatsApp, RCS) and voice APIs; the application layer is an AI agent platform [0][3]. Plivo advertises one-hop global routing for sub-500ms latency (700-900ms optimal response), AI noise cancellation, natural prosody, tone and hallucination control, smart turn detection, barge-in and silence handling, plus automated simulations, evaluations, real-time observability and goal-based optimization. Agents can be built programmatically with LiveKit or Pipecat and SDKs for Python, Node, Go and REST, or without code in a visual/prompt studio. Security controls include TLS, AES-256 at rest, regional data residency and RBAC [0].
Go-to-market
Product-led self-serve entry combined with enterprise sales. Prospects can start free with $10 in credits and no credit card and deploy an agent via CLI or the hosted console, while larger deployments route to a "Talk to sales" enterprise plan with custom pricing and compliance terms [0][2]. Developer-oriented distribution is supported through APIs, SDKs and integrations with third-party agent frameworks such as LiveKit and Pipecat [0].
Businesses that need to communicate with customers at scale, including enterprises and developer teams building voice, SMS, WhatsApp and chat interactions. Y Combinator's profile cites thousands of businesses worldwide, naming Uber, Meta, Zomato and GoDaddy [4]. Use cases span customer support, marketing engagement and lead qualification [4], as well as order tracking, payment collection, feedback surveys and identity verification [0].

Risks & controversies
No controversies are documented in the available sources. Data points conflict across sources: employee count is given as 320 by Y Combinator [4], "100+" by Plivo's about page [3] and 51-200 by a third-party directory [5]; country coverage is stated as 150+ on the homepage [0] and 190+ on the about and pricing pages [0][3][2].
