VoiceRun was founded by Nick Leonard and Chad Jaquays to give enterprises serious, developer-grade infrastructure for building voice AI agents. As voice agents moved from novelty to production, many teams found that no-code builders broke down under real-world complexity: hard-to-debug flows, limited control over logic, and unpredictable behavior. VoiceRun's answer is a code-first foundry that treats voice agents like software, with the testing, version control, and integration depth that engineering teams expect.
The platform lets developers compose voice agents from intelligent building blocks while retaining fine-grained control over conversation logic, tool calls, and integrations. Rather than abstracting everything behind a drag-and-drop interface, VoiceRun gives teams the primitives to build exactly the agent behavior they need and to debug it rigorously. The company frames its ambition as a foundry capable of producing billions of voice agents — infrastructure that any enterprise can use to spin up reliable, controllable agents at scale.
This focus on control and reliability is aimed squarely at enterprises deploying voice agents in high-stakes settings where a misbehaving agent has real consequences. By prioritizing developer experience and production-readiness, VoiceRun differentiates from the many demo-friendly but brittle voice tools that proliferated as the category exploded.
In January 2026 VoiceRun announced a $5.5 million seed round led by Flybridge Capital, with participation from RRE Ventures and Link Ventures. The company says it will use the funding to expand its voice AI platform, scale enterprise deployments, and accelerate go-to-market.
VoiceRun's bet is that as voice agents become standard across enterprises, the winners will need robust, code-first infrastructure — and that being the foundry beneath those agents is a durable position in the stack.
