CAMBRIDGE, MA – VoiceRun, a full‑stack enterprise platform for Voice AI, today announced a $5.5 million seed round led by Flybridge Capital Partners.

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.
