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.

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.
