Voice AI startup AethexAI has raised $3 million in pre-seed funding to develop localised customer support automation for 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, telecom executives, and AI researchers from Anthropic.
