VoiceRun, which builds a platform for creating enterprise voice AI agents, raised a $5.5m seed round, announced on 14 January 2026. Flybridge Capital Partners led the round, with participation from RRE Ventures and Link Ventures, according to SiliconANGLE and TechCrunch.
No valuation was disclosed. Pulse 2.0 reported that the company is based in Cambridge, Massachusetts, and was formerly called Prim AI. It graduated from Link Studio, a division of Link Ventures, one of the seed investors. Neither source gave a founding year or headcount.

What VoiceRun does
VoiceRun is a code-first platform. SiliconANGLE reported that customers keep ownership of their application code, while the platform handles orchestration, telephony and evaluation tools. It supports deployment in a public cloud, a virtual private cloud or on premises.
TechCrunch described it as a place where developers and coding assistants build, launch and scale voice agents, with A/B testing and one-click deployment. Nicholas Leonard, the chief executive, told the outlet that coding agents "are going to do a far better job operating in code than in a visual interface".
Pulse 2.0 described three layers: infrastructure and orchestration, developer control, and enterprise tooling. Orchestration covers real-time handling of speech-to-text, large language models and text-to-speech, including turn-taking, telephony integration and latency management. The platform also provides telemetry, evaluation workflows that use language models, and synthetic data generation for regression testing. It uses standard Git and command-line workflows, and the company works with a forward-deployed engineering model.
Customers and targets
SiliconANGLE said VoiceRun is aimed at restaurants, insurance, banking and telecommunications. Early rollouts cover phone ordering and reservations, contact-centre triage and lead qualification.
TechCrunch's only example was an unnamed restaurant-technology company building an AI phone concierge for food reservations.
Pulse 2.0 named one customer, Tivly, which moved from development to production in weeks. Chad Jaquays, Tivly's chief operating officer and co-founder, said VoiceRun took the company "from zero to production deployment in weeks". That is a customer comment issued with the announcement.
What the money is for
SiliconANGLE reported that the funding will go toward expanding go-to-market efforts and preparing the platform for broader production use. Leonard said many enterprise projects stall between an impressive demo and a dependable production rollout.
He told TechCrunch that "There are great voice agents today, but they won't be ubiquitous until the voice agent factory is built."
Leonard also said in the Pulse 2.0 report that the round accelerates the company's work on the infrastructure that makes enterprise voice systems scalable and durable.
Who invested
Chip Hazard, co-founder of Flybridge, said VoiceRun offers the missing piece that lets enterprises build, govern and scale voice deployments.
TechCrunch named Leonard as chief executive and Derek Caneja as chief technology officer. SiliconANGLE and Pulse 2.0 named only Leonard. Pulse 2.0 reported no earlier funding, so none is listed.
