Threll.ai
AI phone agents
Threll.ai builds AI agents that answer the phone. One agent handles voice and chat on the same context, so a customer who switches channel does not have to start over.
The service runs directly on Telenor's SIP trunk. That means Nordic infrastructure, HD voice and encrypted speech traffic, and none of the latency that comes from routing audio to US servers and back.
Threll.ai was spun out as its own company in February 2025 and is owned by Apps AS.

Problem
The phone rings when nobody can pick it up. At 11:30 the therapist has both hands on a patient. At 21:40 the office is empty. Callers rarely leave a message. Most of them dial the next number on the list and get an answer there.
The call never reaches a system. A company knows how many jobs it won. Almost none know how many enquiries never became a conversation.
What we built
Threll.ai builds AI agents that answer the phone. A threll takes incoming calls or makes outgoing ones, on the number the company already has. It answers questions, books in the calendar, judges urgency by the customer's own rules and transfers to the right person when a case needs a human.
Seven ready-made setups cover the most common jobs: missed calls, customer support, receptionist, reminders, phone surveys, job interviews and lead qualification.
Voice and chat run on the same context, so a customer who switches channel does not have to start over. The agent states in its first sentence that it is an AI assistant, and that cannot be turned off.
Every call in one list, with its outcome: booked, routed, filtered or resolved. The whole conversation in writing, with summary and sentiment at the top.
We do not take over the on-call rota. We make sure it is only woken when that is worth doing.
Nordic infrastructure
Threll runs directly on Telenor's SIP infrastructure. The company keeps its number, its operator and its subscription, and connects the threll as call forwarding on no answer, on busy or outside opening hours. No new hardware, no VoIP setup.
Data is stored in Nordic data centres under GDPR, with a data processing agreement as standard. The customer decides how long recordings and transcripts are kept, and can delete them at any time.
Norwegian, Swedish and Danish are specially trained through Threll Voice Lab on real Nordic voices. That is why the agent copes with dialect rather than only textbook Norwegian read aloud. Another 70 languages are handled, and the agent switches mid-call if the caller does.
Status
Customers set the threll up themselves and are live in an afternoon. Call forwarding takes about ten minutes. Writing what the agent should ask about and what counts as urgent typically takes half an hour. There are three subscription tiers, no setup fee when the customer configures it themselves, and no lock-in on the monthly plan. Current prices are listed at threll.ai/pricing.
Threll.ai AS is a wholly Norwegian-owned company, registration number 935 054 702. The customer platform behind the website runs on Munin: chat, email, voice, analytics and CMS.
