Founders Left Goldman and Meta to Build Voice AI for Overlooked Markets

AI Summary
AethexAI, founded by Mariama Diallo and Ayooluwa Odemuyiwa, raised $3 million to develop voice AI for emerging markets, particularly in Africa and the Middle East.

The Founders' Vision for Voice AI in Emerging Markets

Mariama Diallo and Ayooluwa Odemuyiwa, former employees of Goldman Sachs and Meta, respectively, left their jobs to build AethexAI, a startup focused on developing voice AI for emerging markets, particularly in Africa and the Middle East.

Challenges in Building Voice AI for Africa and the Middle East

The founders identified significant challenges in building voice AI for these regions, including latency and accuracy issues due to the unique dialects and speech patterns. Existing solutions, such as Vapi and LiveKit, were not designed to handle these localized dialects.

AethexAI's Solution: Building Small Models and Orchestration Layer

AethexAI decided to build its own small models and orchestration layer from scratch to handle the localized dialects of English, French, and Arabic. This approach allowed the company to reduce latency and improve accuracy.

The Data Collection and Model Training Process

  • AethexAI used anonymized recordings from a call center partner to train its models.
  • The startup collected audio data by shipping hard drives to radio stations across Africa.
  • A contributor network of university students was established to annotate data and pronounce local names.

The Business Model and Growth Strategy

AethexAI is taking a careful approach to working with clients, offering onsite demos and workshops to help them identify the best use cases for automation. The company is open to working across all industries, with a focus on use cases such as debt collection, customer activation, and KYC verification.

The Market Opportunity and Competitive Landscape

The Africa and Middle East market presents a unique opportunity for voice AI solutions, with enterprises processing roughly three times the call volume of their Western counterparts. AethexAI is well-positioned to capitalize on this opportunity, with its specialized models and on-the-ground partnerships.

The Future Outlook

With its $3 million in pre-seed funding, AethexAI is poised for growth and expansion in the emerging markets. The company plans to continue developing its voice AI solutions and building partnerships with telecoms providers to handle telephony for voice AI calls.
