Five9 is a cloud contact center platform, the kind that runs the whole operation: inbound and outbound voice, chat, email, SMS, and social messaging, plus routing, quality management, and workforce tools. Its Genius AI suite threads through everything, with voice and digital AI Agents that resolve customer conversations on their own, AI Agent Assist that transcribes calls and coaches live reps, and AI Summaries, Insights, and Knowledge doing the after-call cleanup. In 2025 Five9 pushed hard into what it calls Agentic CX, adding an Agentic Engine plus AI Trust and Governance controls.
The company has been at this since 2001, when it started in San Ramon, California, betting that contact centers belonged in the cloud back when they lived in server closets. It went public on NASDAQ in April 2014 at 7 dollars a share under the ticker FIVN. In 2021 Zoom agreed to buy Five9 for roughly 14.7 billion dollars in stock, then shareholders balked and the deal was terminated that September. Longtime CEO Mike Burkland retired, handing the job to Amit Mathradas in February 2026. Today Five9 claims more than 3,000 customers, including Alaska Airlines, PUMA, Omaha Steaks, Wyndham, and Exact Sciences.
Five9 publishes exactly two prices. Digital costs 119 dollars per concurrent seat per month for digital channels only, and Core costs 159 dollars with voice included. The Plus, Pro, and Enterprise bundles are quote only, and everything carries a 50 seat minimum plus usage based charges. Bundled AI covers 3,000 minutes per seat before metered fees kick in, and the serious stuff, AI Agents and virtual agents, is sold as add-ons through sales. Budget accordingly.
Choose Five9 if you run a genuine contact center with 50 or more seats and want voice, digital channels, and AI under one roof from a vendor that will still exist next year. Skip it if you are a small team wanting a simple helpdesk: Zendesk or Intercom will fit better, cost less, and skip the sales calls.

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.
