Comparing Balto and Five9? Both are Contact Center & CCaaS and Voice & Phone AI tools in the directory, which is why buyers put them on the same shortlist.

Balto puts the right words on the agent's screen while the call is still happening. Founded in 2017 in St. Louis by Marc Bernstein and Chris Kontes, it pioneered real-time guidance for contact centers: dynamic checklists, objection responses, and compliance language that appear mid-conversation, exactly when needed, rather than in a coaching session three weeks later. In industries like collections, insurance, healthcare, and home services, where certain sentences are legally required and certain mistakes are expensive, that immediacy is the whole product.
The platform has grown around that core into real-time QA that scores every call as it happens, AI coaching that spots which behaviors need work, live compliance monitoring with manager alerts, and Togo, Balto's voice AI agents for the repetitive calls, like scheduling and account verification, that never needed a human. It integrates with the major contact-center platforms, including Five9, Genesys Cloud, NICE CXone, RingCentral, and 8x8.
Balto raised a $37.5 million Series B led by Stripes in 2021, with RingCentral's venture arm participating, bringing total funding to roughly $52 million, and remains one of the flagship companies of the St. Louis tech scene, with customers like Humana, GEHA, Nelnet, NewRez, and Staples Canada. Pricing is quote-based; there is no public price list.
Choose Balto when what is said on live calls carries real regulatory or revenue weight. Pure digital-support teams will find better fits elsewhere in this directory, but if your operation runs on phone conversations where compliance phrasing and in-the-moment guidance decide outcomes, Balto's real-time focus is still the sharpest in the category.

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.
