Smallest.ai Secures $8 Million to Redefine Voice AI for the Enterprise World

Full-stack business Voice AI platform Smallest.ai raised $8 million in seed capital, headed by Sierra Ventures with contributions from 3one4 Capital and Better Capital. The funding is an important milestone in the journey of the company to make voice the most natural and efficacious interface for business communication.

The funding will enable Smallest.ai to speed up its global expansion in North America and India, develop its product roadmap, and increase its presence in regulated industries such as banking, financial services, retail, healthcare, and IT. The firm has also brought on board Apoorv Sood as its Global Head of Go-To-Market to lead enterprise growth and partnerships globally.

Started by Sudarshan Kamath and Akshat Aandloi, Smallest.ai is designed to scale, be reliable, and be secure. The platform provides on-premise and hybrid deployments that allow companies to have control over their data without compromising on compliance and uptime. It has an architecture designed to support millions of simultaneous customer interactions at low latency and with predictable performance—abilities essential for businesses that need precision and availability.

At the core of Smallest.ai’s technology is a proprietary full-stack Voice AI engine that integrates speech recognition, natural language understanding, and speech synthesis. The company’s Lightning and Electron models have set new benchmarks for response speed and conversational accuracy, achieving latency as low as 100 milliseconds.

Already used by businesses like Paytm, MakeMyTrip, ServiceNow, and Dalmia Cement, Smallest.ai drives thousands of call minutes every month. The platform is also augmenting its multilingual support, with future additions of Hindi, Spanish, and other Indian languages, looking to bring enterprise-class voice automation to more people.

As businesses look for quicker, smarter, and cheaper methods of reaching customers, Smallest.ai is poised to drive this revolution. The firm is expecting 300% growth in the US and 150% year-on-year growth in India next year based on increasing demand for scalable, human-like voice experiences.

Industry forecasts put the global Voice AI Agents market growing from $2.4 billion in 2024 to $47.5 billion by 2034, as the world becomes increasingly AI-driven voice automation. By enabling companies to reduce customer interaction costs by as much as 80%, increase agent productivity by tenfold, and provide around-the-clock coverage, Smallest.ai is transforming how businesses converse at scale—making interactions not only faster, but genuinely more human.
