Team Transition to RadixArk
A segment of the team formerly engaged with SGLang has transitioned to the newly established commercial venture, RadixArk, which was unveiled in August of the preceding year.
RadixArk has its roots in SGLang, which emerged in 2023 from the laboratories of UC Berkeley, where Ion Stoica, a co-founder of Databricks, played a pivotal role.
Sources privy to the situation indicate that a funding round led by Accel has valued the fledgling enterprise at approximately $400 million, although official confirmations regarding the specifics of the investment remain elusive.
Prior to this, the startup secured angel investments from notable backers, including Lip-Bu Tan, the CEO of Intel.
Ying Sheng, an instrumental figure within SGLang and a previous engineer at xAI, departed from Elon Musk’s AI firm to assume the position of co-founder and CEO at RadixArk, as disclosed in a post she published last month. Sheng also holds experience as a research scientist at Databricks.
Neither RadixArk, Ying Sheng, Accel, nor Lip-Bu Tan has responded to requests for commentary.

Emphasis on Inference and Cost Efficiency
Both SGLang and RadixArk concentrate on enhancing inference processing—specifically, the expedited and more efficient execution of models on currently available hardware.
Given that inference generally comprises a substantial portion of server expenditures, tools that optimize this process can yield significant savings in a remarkably short timeframe.
vLLM, a more advanced inference-optimization initiative, has likewise transitioned from an open project to a commercial startup. Discussions are underway regarding a funding effort that aims to exceed $160 million, with a valuation hovering around $1 billion.
The Inference Infrastructure Landscape
The inference-infrastructure market exhibits a trajectory of growth: numerous contenders are gearing up for substantial funding rounds while broadening the application of inference in production settings.
Several industry frontrunners have already begun integrating analogous solutions into their offerings, thereby intensifying competition and inviting new financial infusions.
Similar to SGLang, vLLM also originated from UC Berkeley’s lab. Ion Stoica remains a central figure in the evolution of this domain, serving as a university professor and a co-founder of Databricks, which is behind several entrepreneurial ventures.
Active adoption of inference solutions by large corporations has already been documented within the industry, and recent months have seen a marked increase in interest surrounding inference engineering and its ancillary services.
Venture capital stakeholders have identified this sector as one of the pivotal growth vectors within the AI ecosystem.
RadixArk’s Innovations: Miles and the Open Engine
RadixArk is diligently advancing SGLang as an open engine tailored for AI models. In tandem, the company is developing Miles—a specialized reinforcement learning framework designed to assist enterprises in training and enhancing their models over time.
While the majority of the tools remain available free of charge, RadixArk is beginning to offer hosting services on its platform for a fee.
In the broader context of inference infrastructure, sizable funding endeavors in related projects are surfacing, highlighting the intensifying competition in this arena.
Industry experts regard inference infrastructure as a fundamental segment of the AI ecosystem, especially given the increasing training and deployment of models.
Marina Temkin, a TechCrunch reporter specializing in venture capital and startups, previously covered similar topics for PitchBook and Venture Capital Journal.
With a background in financial analysis and the CFA designation, she is also attentive to the ongoing developments in the sector and RadixArk’s role within the AI landscape.
In summary, market analysts perceive inference infrastructure as a critical layer within the AI ecosystem, characterized by substantial growth potential and the broader integration of models into production processes.
