### Why AssemblyAI AssemblyAI builds best-in-class Voice AI models powering the next generation of voice applications. Our models serve **600M+ inference calls monthly**, process **1M+ hours of audio daily**, and power **2B+ end-user experiences**. The Voice AI space is at an inflection point, and we’re looking for people excited to join a small team and help define the future of the industry.
