AethexAI, a voice artificial intelligence infrastructure startup focused on emerging markets, has secured $3 million in pre-seed funding to expand its localised voice AI systems across Africa and the Middle East.
The round was led by 4DX Ventures, with participation from Enza Capital, Dorm Room Fund, Mojo Ventures, and the Stanford GSB ’26 Fund, alongside angel investors including Stanford faculty members, telecom executives, and AI researchers from Anthropic.
Founded in 2025 by Mariama Diallo and Ayooluwa Odemuyiwa, the company said the funding will support enterprise scaling, platform development, and expansion of engineering capabilities as it targets high-volume enterprise communication markets.
AethexAI builds voice AI infrastructure designed for emerging markets, where businesses often struggle with large customer call volumes, limited support staff, and inconsistent telecom conditions.
The company is positioning its platform as an automation layer for customer service and enterprise voice operations. Its core technology is the Kora 1 model series, a set of self-hosted speech models ranging from 300 million to 1.7 billion parameters, optimised for low-latency voice processing.

The models are designed to handle code-switching, informal speech patterns, and diverse dialects of English, French, and Arabic, which are commonly used across Africa and the Middle East.
The platform also integrates telephony infrastructure and workflow orchestration tools, enabling enterprise deployment for use cases such as KYC verification, debt collection, customer onboarding, and activation.
The company system is already operating at scale, handling more than 17,000 calls daily, with pricing starting at approximately $0.03 per minute.
Co-founder Mariama Diallo said:
“Existing tools simply didn’t work in their environments. That’s why we built our own model stack and infrastructure from the ground up, designed for how these markets actually operate.”
Co-founder Ayooluwa Odemuyiwa said:
“Latency, cost, poor handling of code switching, and weak performance under packet loss and jitter led these systems to break in production. The fix required redesigning the entire stack.”
Investors in the round include 4DX Ventures, Enza Capital, Dorm Room Fund, Mojo Ventures, and the Stanford GSB ’26 Fund, as well as strategic angels from academia, telecoms, and AI research.
AethexAI says it is targeting a combined market of over 1.5 billion people, where voice remains a dominant channel for enterprise communication across emerging markets.
