Callab AI builds AI voice agents that plug directly into the legacy, on-premises phone systems most large call centers still run on. Instead of forcing a cloud migration, its carrier-grade telephony stack connects to hardware like Avaya, Cisco UCM, and Mitel over SIP trunks and automates a large share of inbound calls within about a week. Founded by Tunisian engineers Haithem Kchaou and Chehir Dhaouadi and part of Y Combinator's Spring 2026 batch, the company handles calls in Arabic and its dialects plus several other languages, and serves customers across North America, Europe, and the Middle East.
Cozmo AI (formerly CozmoX AI) builds multimodal 'AI employees' that answer calls, read documents, and complete regulated business processes end to end for financial services, insurance, and enterprise operations. Founded by Alok Kumar and Nuha Hashem - the team behind the Gen Z neobank Zywa - the Y Combinator W22 company runs from San Francisco and Dubai, and says its agents handle voice conversations in 70+ languages including multiple Arabic dialects.
