VoiceRun, a startup developing voice agents, raised $5.5 million in seed funding led by Flybridge, with participation from RRE Ventures and Link Ventures. The company, initially known as Prim AI, launched VoiceRun to address the gap between low-quality no-code tools and resource-intensive specialised solutions by enabling developers and coding assistants to launch and scale voice agents through a code-first platform.
VoiceRun differentiates itself by allowing users to code agent behaviour directly, contrasting with no-code platforms like Bland and Retell AI that enable quick demos through visual diagrams, and sophisticated tools like LiveKit and Pipecat that offer maximum developer control. Beyond coding agents, the platform provides A/B testing capabilities and one-click deployment whilst ensuring teams retain full code ownership, with deployment options including cloud, customer VPC, or on-premises environments to meet security and compliance requirements. Co-founder and CEO Nick Leonard stated the seed round accelerates infrastructure development to make enterprise voice systems scalable and durable, emphasising that widespread voice agent adoption requires building the voice agent factory, which VoiceRun aims to provide.
The funding positions VoiceRun within a competitive landscape where voice AI startups secured billions of dollars in 2024 from the substantial capital flowing into AI companies generally. The seed round enables VoiceRun to scale its code-first approach, targeting the enterprise market with flexible deployment options and developer-centric tools that balance ease of use with technical control.
