# Smallest AI Smallest AI builds full-stack, low-latency enterprise voice AI. Its in-house models such as Lightning (TTS, \~100ms), Pulse (STT, 38 languages), Electron (sub-3B OpenAI-compatible LLM), and Hydra (full-duplex speech-to-speech) that power the Waves API suite and the Atoms voice-agent platform. Enterprises use it to automate support, sales, collections, and scheduling with agents that sound human and run in production. Smallest AI (legal: Smallest, Inc.) was founded in 2023 by Sudarshan Kamath (CEO) and Akshat Mandloi (CTO), former Robert Bosch engineers. It is headquartered at 311 California Street, Suite 320, San Francisco, CA 94104, with engineering in Bengaluru, India, and raised an $8M seed round led by Sierra Ventures in October 2025 ($8.26M total). Compliance: SOC 2 Type II, HIPAA, GDPR, ISO 27001, PCI. Docs are built on Fern; append .md to any docs URL for Markdown or /llms.txt for a page-level index.
