VoiceRun, a full-stack enterprise platform for Voice AI, announced a $5.5 million seed round led by Flybridge Capital Partners, with participation from RRE Ventures and Link Ventures. The funding will be used to expand the company's Voice AI solutions and go-to-market efforts as enterprises move beyond demos and pilots to deploy voice agents that meet reliability, security, and governance expectations at scale.

With 85% of enterprises expected to use AI agents by the end of 2025, control of in-house development and infrastructure matters more than ever. VoiceRun meets this need with a code-first approach and a forward-deployed engineering model, enabling technical teams to ship quickly without surrendering control. Customers own their application-layer code, and VoiceRun provides the orchestration layer for speech-to-text, large language models (LLMs), and text-to-speech (TTS), turn-taking, telephony, and latency management, along with the tooling to continuously measure, iterate, and improve systems in real time.
