VoiceRun, an enterprise platform for building and deploying Voice AI, has raised a $5.5 million seed round led by Flybridge Capital Partners, with participation from RRE Ventures and Link Ventures. The company said it will use the funding to expand its product and go-to-market efforts as more enterprises push voice agents from pilots into production deployments.
Based in Cambridge, Massachusetts, VoiceRun is positioning itself as a “code-first” alternative to packaged voice-agent products, arguing that many enterprise initiatives stall after an impressive demo due to reliability, security, and governance requirements. The company’s approach pairs an orchestration layer with a forward-deployed engineering model intended to help technical teams ship quickly while keeping ownership of application-layer code.
VoiceRun said its platform provides real-time orchestration across speech-to-text, large language models, and text-to-speech, along with turn-taking, telephony integration, and latency management. It also includes tooling designed to measure and improve performance over time, including telemetry, LLM-based evaluation workflows, and synthetic data generation for regression testing.
The company described three core layers of functionality: infrastructure and orchestration, developer control, and enterprise tooling. On deployments, VoiceRun said customers can run the platform in a public cloud environment, in a customer’s virtual private cloud, or on premises to meet data-handling and compliance needs.
On developer workflows, the company said teams can use standard Git and command-line processes with full code ownership, enabling integration with internal APIs and complex business logic without depending on vendor roadmaps. For enterprise operations, VoiceRun highlighted end-to-end observability and evaluation tools intended to drive continuous iteration and improve containment and accuracy.
VoiceRun said early deployments span phone ordering and reservations, contact-center triage, and lead qualification—use cases where low latency is critical and organizational controls can slow adoption. The company also emphasized flexibility features such as VPC options and approved model lists to align deployments with security and compliance reviews.
As part of its announcement, VoiceRun said it has graduated from Link Studio, a division of Link Ventures, and rebranded from its prior name, Prim AI, to better reflect its enterprise focus as it scales.
One early customer, Tivly, said VoiceRun helped move from initial development to production deployment in weeks and provided ongoing evaluation tooling to guide weekly improvements in accuracy and customer satisfaction.
KEY QUOTES:
“Voice AI is having a moment, yet many enterprise projects stall between an impressive demo and a dependable production rollout. This seed round accelerates our work on the infrastructure that makes enterprise voice systems scalable and durable. We give teams code ownership, deployment flexibility, and deep observability so they can move fast, clear security reviews, and deliver production-ready solutions at scale.”
Nick Leonard, Co-Founder and CEO, VoiceRun
“Voice is the best interface for many AI applications, but bringing these applications into production presents a paralyzing build vs. buy decision. VoiceRun offers the missing piece which empowers enterprises to build, govern, and scale world-class voice deployments.”
Chip Hazard, General Partner and Co-Founder, Flybridge Capital Partners
“VoiceRun took us from zero to production deployment in weeks. Then their tooling and AI evaluations show us exactly what to improve each week, so accuracy and customer satisfaction keep climbing. They accelerated our AI transformation, and gave us the comfort of security, compliance, and code ownership.”
Chad Jaquays, COO and Co-Founder, Tivly
