In 2026 the tidy world of customer-service chatbots split in two. On one side, legacy vendors like LivePerson and Verloop.io are being sold for parts; on the other, voice-native upstarts like Retell AI and deep-pocketed enterprise players like Kore.ai race to answer your next call in under a second.
While Zendesk rewires customer service around outcome-priced AI agents, Sweden's Teneo.ai is chasing the same market with a different promise: 99% accuracy, no LLM output reaching your customers, and voice bots that answer millions of calls a month.
The YC-backed voice startup raised about $5 million, then rode 650% growth to a $60 million run rate - selling AI phone agents by the minute while Microsoft, Salesforce and Cresta chase the same calls.

Two companies - one a Norwegian chatbot pioneer, the other a Y Combinator voice startup - are pulling conversational AI in opposite directions. Whoever wins gets to decide how you talk to every business you deal with.

The New York startup is betting the future of the call center isn't fewer humans and cheaper bots - it's AI voice agents that sound like your best rep, never sleep, and have already worked their way through 500 million calls.
