Smallest.ai raised an $8M seed led by Sierra Ventures to supercharge high‑speed, multilingual enterprise voice agents.

Smallest.ai just closed an $8 million seed round led by Sierra Ventures, with support from 3one4 Capital and Better Capital. The funding will let the startup push its goal of ultra‑fast, production‑ready multilingual voice agents into contact centers and beyond.

What makes their pitch compelling is that they own the full voice stack—from speech recognition and understanding to synthesis—delivering human‑level speed and emotional nuance. Their models, like the Lightning TTS engine (~100 ms latency) and Electron model (~10× faster time‑to‑first‑byte than GPT‑4.1 Mini), are built for scale and vertical customization.

Already, Smallest.ai is powering millions of call minutes monthly in banking and financial services across the U.S. and India. With this capital, they’ll broaden into retail, healthcare, and IT, pushing toward a future where voice AI is swift, expressive, and ready for real enterprise use.

Key Points:

  • Raised $8M seed round led by Sierra Ventures, joined by 3one4 Capital and Better Capital

  • Owns full-stack voice AI—speech recognition, understanding, and synthesis

  • Lightning TTS boasts ~100 ms latency; Electron model beats GPT‑4.1 Mini byte‑time

  • Currently handles millions of minutes monthly in US and India contact centers

Takeaway: By owning every layer of voice AI, Smallest.ai offers enterprises fast, secure, and emotionally aware voice agents—scalable and customizable by industry, deployable in days, and now armed with fresh funding to reach new sectors globally.

David AI raised $50 million in Series B to expand its research-driven audio datasets for speech AI.

David AI, a San Francisco audio data research lab founded in 2024, has just closed a $50 million Series B round co‑led by Meritech and NVIDIA, bringing its total funding to around $80 million. The startup specializes in building high‑quality, diverse audio datasets that capture the nuance of human speech—tone, emotion, accent, dialect and context—and applies rigorous research methods to curate and evaluate them at scale. Its real‑world data underpins voice AI models across domains, and now with fresh capital it’s bulking up research operations, engineering talent, and collaborations with AI labs and hardware partners worldwide to improve real‑world model performance. David AI is betting big on audio as AI’s natural interface, aiming to power intuitive assistants, wearables, robots and generative media.

Key Points:

  • Raised $50 million Series B led by Meritech and NVIDIA

  • Total funding reaches approximately $80 million

  • Focuses on research‑grade diverse audio datasets for speech AI

  • Funding will scale teams, research ops, and global AI partnerships

Takeaway: This round underscores that as AI advances, the bottleneck isn’t models but the high‑fidelity, context‑rich audio data needed to teach machines to truly understand human speech—and David AI is positioning itself as the key infrastructure provider in that space.
