Smallest.ai, a full-stack enterprise voice AI platform, has raised $8 million in seed funding led by Sierra Ventures, with participation from 3one4 Capital and Better Capital. The startup plans to use the fresh capital to expand operations across North America and India, accelerate product innovation, and deepen its presence in regulated sectors such as banking, financial services, retail, healthcare, and information technology.
The company projects a 300% growth in the U.S. market and 150% year-on-year growth in India over the next 12 months. This surge is due to rising enterprise demand for scalable, natural voice AI solutions that enhance customer interactions and operational efficiencies.
To lead its global expansion and enterprise partnerships, Smallest.ai recently appointed Apoorv Sood as Global Head of GTM. Sood brings extensive experience in scaling enterprise technology ventures and will oversee growth strategies worldwide
The central piece behind Smallest.ai’s offering is a proprietary full-stack voice AI platform that integrates speech recognition, natural language understanding (NLU), and speech synthesis. This integration enables real-time, human-grade voice interactions across a variety of enterprise use cases.
Designed specifically for enterprises requiring reliability, scale, and compliance, Smallest.ai’s platform supports customer support, debt collection, and pre-sales automation. Its proprietary Lightning model and supporting ecosystem allow enterprises to automate millions of voice interactions daily with high accuracy and low latency.
The platform supports more than 100 distinct voices and multiple languages, currently including English, Hindi, and Spanish, with plans to add further Indian languages soon. This multilingual support is vital for enterprises operating in diverse markets and seeking localized customer engagement.
Market Outlook
Smallest.ai’s technology is already deployed by clients like Paytm, MakeMyTrip, ServiceNow, and Dalmia Cement. These organizations leverage the platform’s real-time voice AI capabilities to improve customer experience while reducing support costs.
A key differentiator for Smallest.ai is its focus on industries with stringent regulatory requirements. The company offers flexible deployment options including on-premises and hybrid cloud setups, ensuring compliance with data privacy and security standards such as SOC 2 Type II, HIPAA, and PCI.
The enterprise voice AI market is on a rapid growth trajectory, with analysts projecting expansion from $2.4 billion in 2024 to $47.5 billion by 2034. This growth is driven by increasing adoption of voice assistants and AI agents that enhance customer interactions in contact centers.
Unlike many voice AI tools that stitch together components, Smallest.ai owns its full stack, resulting in ultra-low latency, high accuracy, and seamless integration into existing enterprise infrastructure including CRMs, telephony, and email systems.
Founder and CEO Sudarshan Kamath emphasizes that Smallest.ai was built with a focus on scale, reliability, and trust, particularly for regulated industries. He notes that the new funding gives the company the momentum to take its vision global while maintaining enterprise discipline.
“This capital gives us the push to take that vision global with the same enterprise discipline we started with,” said Sudarshan.
