Unlocking Real-Time Communication: How LiveKit’s Tools Enhance OpenAI’s Voice Mode

For tech companies, delivering high-bandwidth, multimodal data—such as real-time audio and video—is a significant challenge. Many firms opt for in-house solutions, which often demand extensive maintenance. To address this issue, Russ d’Sa and David Zhao founded LiveKit, an innovative open-source software package designed for seamless real-time audio and video transmission.

The Genesis of LiveKit

Launched in 2021, LiveKit quickly gained traction, revealing its potential for commercial success. According to d’Sa, the platform now boasts over 500 paying customers and more than 100,000 developers utilizing its cloud and open-source offerings.

LiveKit’s Impact

LiveKit is making waves in various industries. It serves as the backbone for approximately 25% of 911 emergency calls in the U.S. and is employed by notable aerospace companies for launch and flight observation. Major organizations like Skydio use it for police drone teleoperation, and it is integrated into solutions by Oracle and Adobe for government applications.

From Concept to Startup

The idea for LiveKit emerged when large companies, including Spotify, Oracle, and Reddit, began experimenting with the platform and requested a cloud-hosted version. D’Sa, a former engineer at Twitter, and Zhao, who previously directed engineering at Motorola, decided to transform LiveKit into a startup and launched LiveKit Cloud—a managed version of the original project.

Features and Offerings

Today, LiveKit powers various applications, including OpenAI’s ChatGPT Voice Mode. The platform provides SDKs, tools, and APIs that facilitate the creation of immersive streaming audio and video experiences. Its clientele features industry titans such as Meta, Microsoft, alongside innovative companies like Character AI, Speak, and Fanatics.

Future Plans and Innovations

Headquartered in San Jose, California, LiveKit currently employs around 50 people and is focused on enhancing its engineering and product teams. The company is also working on an “elastic agent compute service”—a product designed to deploy and automatically adjust the scale of voice agents, such as chatbots.

Vision for the Future

According to d’Sa, LiveKit aims to become an AI-native cloud provider, akin to what Stripe has achieved for payments. “What LiveKit is ultimately building is ‘AIWS’,” he stated, emphasizing the company’s mission to revolutionize communications.

Financial Health and Growth

LiveKit’s financial outlook is promising. Last year, the company reported a run rate exceeding $10 million. Recently, it secured $45 million in a Series B funding round led by Altimeter Capital, with contributions from Redpoint Ventures and Hanabi Capital.

In summary, LiveKit is on a trajectory of growth and innovation, positioning itself as a formidable player in the realm of real-time communications.
