telli

telli builds what it describes as the first AI-native phone system: AI voice agents that handle inbound and outbound calls for businesses, allowing them to reach leads immediately and to run customer communication at scale. The agents support more than 20 languages, and the company reports that its system has handled millions of calls. Founded in 2024, telli operates as a small, lean team.

The product sits at the intersection of several technical domains: AI voice agents, speech and conversational AI, telephony and phone systems, and multilingual natural-language processing. Its principal applications are in customer support and call centres, lead outreach and sales, and telecommunications. The company reports annualised revenue of over $2m.

telli states that its founding team previously ran a 150-person internal call centre at Enpal, and that its mission is to end the era of low-quality call centres. The stated way of working favours small, focused teams that ship to production daily, optimise for impact over facetime, and operate with low ego and high ownership.
