Conversational AI & Chatbots Market: Smallest.ai raises $13M for humanlike voice AI
Smallest.ai, a startup founded in late 2024, raised $13 million in a Series A round to develop a small, voice-specific AI model intended for real-time conversational agents that sound human. The round was led by Seligman Ventures with participation from Sierra Ventures and 3one4 Capital, bringing total funding to over $21 million. Smallest.ai's approach uses a lightweight real-time voice model for immediate interaction and falls back to larger foundational LLMs when needed. The company targets enterprise customer support use cases—handling accents, multiple languages, and noisy environments—and counts RingCentral and Truecaller among existing customers. Competitors named include ElevenLabs, Cartesia and regional player Sarvam. Sudarshan Kamath is founder and CEO.
A Series A funding for a startup pursuing low-latency, voice-specific AI models may influence enterprise customer-support voice solutions and competitive dynamics in voice AI, but it is not platform-level or industry-shifting.
