Kore.ai is an enterprise platform for building and orchestrating AI agents, with customer experience as one of its flagship uses. Teams design agents using no-code visual tools or pro-code SDKs, deploy them across web chat, messaging, voice, and contact-center channels, and manage them with the security and analytics a large organization demands. Its agentic contact-center suite spans intelligent self-service, AI-powered routing, and real-time agent assist, and a growing set of prebuilt vertical apps for banking, healthcare, retail, HR, and IT gives buyers a running start instead of a blank canvas.
The scale here is the headline. Kore.ai says its platform automates more than a billion interactions a year and has delivered over a billion dollars in cumulative customer cost savings, and it has been named a leader in independent analyst evaluations of conversational AI and cognitive search. Its newer generative application platform, GALE, and an AI-first agent platform push the product deeper into the agentic era.
There is a nice against-the-grain story to the company, too. Kore.ai was founded in 2014 by serial entrepreneur Raj Koneru, whose resume includes four earlier companies, and it grew up not in Silicon Valley but in Orlando, Florida, only later opening a West Coast office. It has raised well over four hundred million dollars across its rounds, including a 2026 growth investment, and became a launch partner for Microsoft's agent ecosystem while earning agentic credentials with AWS.
Big names like AT&T, Coca-Cola, and Airbus are among the hundreds of Global 2000 enterprises it serves, and pricing is entirely custom, scaled to the sessions, seats, and add-ons a given deployment needs. For large organizations that want a single, proven platform to build and run both customer-facing and employee-facing agents across every channel, without stitching together half a dozen point tools, Kore.ai is a serious heavyweight worth putting on the shortlist and taking for a proper test drive.

PolyAI answers the phone. While most of this directory started with chat and added voice later, PolyAI has been voice-first since three Cambridge machine-learning PhDs, Nikola Mrkšić, Pei-Hao Su, and Tsung-Hsien Wen, founded it in London in 2017 out of the university's Machine Intelligence Lab. Its agents are known for sounding genuinely human and for surviving the things that break lesser systems: interruptions, accents, background noise, and callers who change their mind mid-sentence. Restaurants, hotels, banks, and utilities use it to answer every call instantly, day and night, with customers like PG&E, UniCredit, Golden Nugget, and Fogo de Chao on the roster.
The platform matured into what the company calls an agentic dialog platform: Agent Studio for building and managing agents without code, a developer kit for deeper work, and Raven, a proprietary conversation model trained on more than a billion enterprise conversations. Compliance boxes (SOC 2, HIPAA, PCI) are ticked, which matters because taking payments and health information over the phone is exactly where voice AI earns its keep.
Investors have noticed the wedge. In December 2025 PolyAI raised an $86 million Series D at a valuation around $750 million, with NVIDIA's venture arm participating, bringing total funding past $200 million. Commercially it bills on usage, priced per minute of conversation, with rates scoped to your call volume rather than published on the site.
Choose PolyAI when the phone is your problem. If most of your support pain is hold music, missed calls, and staffing the night shift, a voice-native specialist will beat a chat-first platform's bolted-on telephony, and PolyAI is one of the most proven voice specialists in the market.
