San Francisco-based AI research lab Smallest.ai announced it has raised a $13 million Series A round led by Seligman Ventures, alongside Sierra Ventures and 3one4 Capital, bringing its total capital raised to over $21 million. New investments will help to speed up the growth of its core Voice 4.0 platform for enterprises that work in finance, health care, and contact centers. As the worldwide Voice AI market size forecasted for 2024-2034 increases from $2.4 billion to $47.5 billion, existing systems still remain limited because of sequential processing issues, high latency, and unnatural dialogue flow. In order to fix the mentioned architectural limitations, Smallest.ai introduced its unique speech-to-speech model called Hydra, which works using asynchronous processing capabilities.

“Voice AI has gone through three generations of innovation, but each generation has ultimately hit the same wall,” said Sudarshan Kamath, founder and CEO of Smallest.ai. “The industry has focused on making models larger when the real challenge is architectural. Humans don’t wait for someone to finish speaking before they begin thinking. We listen, think, and respond simultaneously. Voice AI needs to work the same way. That’s why we built Smallest.ai around a real-time architecture that processes speech as it arrives, enabling faster, more natural conversations without sacrificing intelligence. By rethinking the stack instead of simply scaling models, we’re reducing latency to the point where voice interactions feel genuinely human.” “Voice AI is creating a real impact on life and work,” said Ashish Kakran, Managing Partner at Seligman Ventures. “Developers now increasingly talk to their machines instead of typing code. Smallest.ai is taking a fundamentally different approach to the category by rethinking architecture itself. Customers get an efficient vertically integrated stack and don’t need to waste time stitching models together. We believe the next generation of enterprise voice will be powered by Smallest AI.” Currently powering high-volume voice operations for clients like RingCentral and Truecaller, Smallest.ai plans to expand its 60-person workforce to meet surging global enterprise demand.
