Düsseldorf, Germany
Base version free: 500 call minutes a month and one phone number; paid tariffs for more minutes or system connections
Demo on request
Best for: German-speaking small and mid-size firms that want a phone agent running without a consulting project
sipgate sona is an AI phone agent that sipgate GmbH of Düsseldorf adds to the business phone accounts it already sells. The base version has no fee and covers 500 call minutes a month and one number, and sipgate explains the price by saying it owns its language models, servers and telephony, so there is no third-party model licence to pass on.
sipgate quotes more than 40,000 business customers for its telephony, which is its own figure. The agent reads CRM or ERP data before a call, books appointments and creates tickets during it, and a dashboard shows live calls, escalation rate and common topics. Paid tariff prices, the list of supported languages and the claim that data stays in Germany were not independently verified, and the product page is in German.

Best for: Enterprises that want to automate large volumes of inbound customer service calls
PolyAI is a London company founded in 2017 as a spin-out from the University of Cambridge, with Nikola Mrksic, Pei-Hao Su and Tsung-Hsien Wen as co-founders. The tool page reports more than 100 enterprise customers in 25 countries, over $200 million in total funding and references including Marriott, Caesars Entertainment, UniCredit and Foot Locker.
The company builds voice assistants for customer service that let callers speak freely, interrupt and change topic, which it contrasts with menu-driven IVR.
