Background and Funding
The open‑source project vLLM, known for accelerating AI inference, has been transformed into a venture‑backed startup named Inferact. The company announced a seed‑stage financing round that raised $150 million, valuing the business at $800 million. The round was co‑led by two prominent venture capital firms, Andreessen Horowitz and Lightspeed Venture Partners.
Founders and Origin
Inferact is led by CEO Simon Mo, one of the original creators of vLLM. The technology was incubated in 2023 at the University of California, Berkeley lab founded by Databricks co‑founder Ion Stoica. The move from an open‑source project to a commercial entity reflects a broader industry shift toward monetizing AI inference capabilities.
Market Position and Early Customers
Existing users of vLLM include Amazon’s cloud service platform and a widely used shopping application. These early adopters underscore the demand for faster, more cost‑effective AI inference solutions as businesses look to deploy large language models at scale.
Industry Context
The fundraising follows similar commercialization efforts, such as the SGLang project’s transition to a startup called RadixArk, which also secured capital at a high valuation. Both vLLM and SGLang were born from the same UC Berkeley lab, highlighting the lab’s role as a catalyst for AI infrastructure innovation.
Future Outlook
With substantial seed capital and backing from top venture firms, Inferact is positioned to accelerate the development and adoption of vLLM technology. The company’s focus on inference—running AI models in real‑world applications—aligns with the industry’s pivot from model training to practical deployment, promising faster and cheaper AI services for enterprises.
