Cognigy, now part of contact-center giant NiCE, builds AI agents for the enterprise, with a particular strength in voice. Its flagship Cognigy.AI platform deploys autonomous agents that reason, adapt, and take action across voice and digital channels in more than a hundred languages, and it pairs them with an Agent Copilot that assists human reps and a Knowledge AI layer that grounds answers in your content. A no-code conversation builder lets teams design and orchestrate sophisticated flows without heavy engineering, and the platform integrates tightly with contact-center systems like Genesys and Amazon Connect.
The company has serious enterprise credibility. Founded in 2016 in Dusseldorf, Germany, by Philipp Heltewig and Sascha Poggemann, Cognigy grew into a repeat leader in analyst rankings for conversational and agentic AI, and in 2025 it was acquired by NiCE in a cash-and-stock deal reported around nine hundred and fifty million dollars, described as one of Europe's largest AI acquisitions. It now runs both inside NiCE's broader platform and as a standalone product, so existing customers were not left stranded.
The client roster is a roll call of household names, including Lufthansa Group, Bosch, Toyota, Mercedes-Benz, Nestle, and DHL, with well over a thousand brands relying on it to automate conversations at genuinely large scale. Pricing is enterprise and custom, with no public price list or self-serve tier, and voice, chat, and add-ons like Agent Copilot are typically quoted separately, so this is a considered purchase rather than an impulse buy.
For big organizations that need to automate high call volumes across many languages, keep human agents in the loop, and slot AI into an existing contact-center stack rather than replacing it, Cognigy is one of the most established and well-regarded choices on the market today, and the deep-pocketed NiCE backing only extends its already-broad enterprise reach.

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.
