LiveKit has secured $100 million in a Series C funding round, aiming to enhance its developer platform that facilitates the building of voice, video, and physical artificial intelligence agents. The round, which values the company at $1 billion, was announced by co-founder and CEO Russ d’Sa in a blog post on Thursday, January 22.
This funding follows an April Series B round during which LiveKit raised $45 million. The platform is currently utilized by over 200,000 developers and teams, including AI and robotics labs and several Fortune 500 companies, to create AI applications capable of real-time interaction with the world.
LiveKit has played a crucial role in developing ChatGPT Voice Mode in collaboration with OpenAI, as noted in the previous funding announcement. Since its launch, voice AI derived from this collaboration has been integrated into thousands of applications across various sectors, including financial services, healthcare, retail, customer support, education, and robotics. These applications enable voice agents to perform a range of tasks, such as processing claims, tutoring students, triaging patients, supporting customers, and interviewing candidates.
According to d’Sa, enterprises are increasingly assessing and constructing voice agents to automate workflows, enhance customer experiences, and unlock new revenue streams. “While many of these use cases are still in the proof-of-concept stage, some are moving into production and operating at real scale,” he stated. Notably, LiveKit’s voice agents are deployed in customer support for leading brands, with Tesla leveraging voice AI for sales, support, and roadside assistance.
Looking ahead, d’Sa predicts that 2026 will mark a significant expansion for voice AI, with deployment across thousands of use cases globally. “Today, large enterprises are evaluating and building voice agents to automate workflows, improve customer experiences, and unlock new revenue,” he said.
Investor Sahir Azam, from Index Ventures, which led the Series C funding, expressed confidence in LiveKit’s trajectory, stating that the company is establishing “one of the most important infrastructure layers in the AI stack.” He emphasized that, in the near term, voice agents are becoming the first point of interaction in call centers and customer workflows. “As robotics and autonomy take off, the same underlying requirements will apply to systems interacting with the physical world through cameras, microphones and sensors,” Azam remarked.
LiveKit’s advancements in voice AI highlight a growing trend in the tech industry, where businesses increasingly depend on AI technologies to streamline operations and foster innovation. The integration of voice agents into various sectors not only enhances efficiency but also caters to evolving consumer expectations for seamless interactions.
As the market for voice AI expands, the implications for communication and customer service are profound. With investments in firms like LiveKit, the tech landscape is poised for further transformation, potentially reshaping how businesses engage with their stakeholders and enhance their operational capabilities.
