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.

Parloa is an enterprise platform built for the hardest support channel of them all: the phone. It focuses on natural-sounding, low-latency voice agents that can actually hold a conversation, and it wraps them in what it calls an AI Agent Management Platform, tooling to build, simulate, test, and safely release fleets of agents at contact-center scale. Though voice is its heart, Parloa has grown multimodal, extending the same agents to chat, WhatsApp, and Microsoft Teams, always aimed at high-volume enterprise contact centers rather than small teams.
The founders come by their voice obsession honestly. Parloa was started in 2018 in Berlin by Malte Kosub and Stefan Ostwald, who had previously built voice experiences and were among the first developers in Germany to create applications for Amazon's Alexa. That head start on talking machines shows up in a product designed to make phone automation feel human instead of robotic.
Investors have noticed in a big way. Parloa became one of Germany's newest unicorns in 2025 and then roughly tripled its valuation to around three billion dollars in early 2026, all while surpassing fifty million dollars in annual recurring revenue, a remarkable clip for a company automating something as unglamorous as inbound calls. Its commercial model is outcome-based, so customers pay for successfully resolved conversations rather than per minute or per seat, and a handoff to a human does not trigger the full charge.
Enterprises like Allianz, Booking.com, HealthEquity, SAP, and Decathlon trust it with serious call volumes across insurance, travel, and well beyond. Pricing is sales-led and geared toward large organizations handling hundreds of thousands of calls a year. If your support pain is concentrated squarely on the phone and you want AI that sounds genuinely natural even at massive scale, Parloa is a specialist built precisely for that particular fight.
