🏙️ SGLang NY Tech Week Happy Hour Recap

Last Wednesday, SGLang hosted a NY Tech Week Happy Hour in NYC, co-hosted with @HOFCapital, @Cloudflare, @CrusoeAI, and @ArklexAI. 380+ registered, 200+ in the room, and one unforgettable night. 🧡

The room was packed with engineers, researchers, and enthusiasts from quant funds, banks, and trading firms, all there to talk about one thing: where inference is headed as LLMs move into latency-sensitive production across trading, research, compliance, and risk.

NYC, you showed up and brought the energy. We loved every minute. Until next time! ☀️

RadixArk has raised $100 million at a $400 million valuation for a software engine and framework that make inference and training more efficient to run. https://t.co/0KVS87MDuh

[Ryan Shmeizer @ryanshmeizer]

Most Al teams today are renting intelligence. @RadixArk is launching with $100M in seed funding to let them operate it instead. Honored to back the team behind one of the most widely used open-source inference engines in the world.

[Vivian Shi @VivianJinjinShi]

Our conviction in RadixArk began in the very first meeting, and has only compounded since.

@ying11231 , @BanghuaZ, and the team are building the open, high-performance foundation for the next generation of AI builders to own, operate, and continuously improve their systems in production.

Proud to be on this journey with them.

[Victor Wang @VictorWangJC]

Huge congrats to our portfolio company @radixark on raising $100M to build frontier-level AI infrastructure that is open and accessible to everyone!

We’re excited to be on this journey with @ying11231, @BanghuaZ, and the rest of the RadixArk team for the decades to come, and we’re looking forward to the future that they’re building where everyone can create, optimize, & deploy their own AI models & products on top of world-class infrastructure.

@HOFCapital @radixark congrats @ying11231 @BanghuaZ & @radixark team!
SGLang went from fast inference framework to default infra for serious builders

Now turning that into a company. Wild.

Excited to see what comes out of this. Big fans at Nebius z

@ying11231 @radixark @lmsysorg Congratulations to the @radixark team on reaching this milestone!

[Ying Sheng @ying11231]

Congrats @radixark !

From SGLang @lmsysorg to Miles, and to future products, RadixArk is dedicated to building a crucible capable of repeatedly producing cutting-edge AI, bringing the best of AI into every household. We believe in a future of AI diversity and hope to drive the integration of AI into every aspect of production and daily life. In the future we envision, AI will become a partner to many companies and individuals, finding ways to self-evolve—in production, in daily companionship, and within virtual worlds.

Everything we have experienced and will continue to experience in the SGLang and Miles open-source communities is unforgettable and highly anticipated. It has been both demanding and exhilarating, allowing us to see friendship, the world, and the boundaries.

Over the past six months, I have witnessed for the first time how a united team moves forward hand in hand, and how deeply passionate they are about creation. Each of us has taken on our respective roles and numerous new tasks for the first time; we are all stepping out of our comfort zones, growing, and creating at a rapid pace.

"It’s the step-by-step journey of a thousand miles that has carried us here today, and the same relentless march that will lead us into the tens of thousands of miles yet to come."

In an era where AI has made ordinary productivity cheaper, relentless, day-to-day refinement has increasingly become the rare key that drives innovation and the future. We hope this will forever remain the soul of RadixArk's culture: focused, uncompromising, humble, and fearless. The underlying logic of creation is not the deliberate pursuit of novelty, but rather independent thinking that remains unswayed by temptation, paired with a meticulous drive for perfection.

@RadixArk launches today with $100M in seed funding to make frontier-grade AI infrastructure open and accessible to everyone, and we’re proud to be early investors. Built by the team behind SGLang, the open-source inference engine serving trillions of tokens daily, we’re honored to be on this journey with @ying11231, @BanghuaZ and the RadixArk team.

More on why we invested below.

[RadixArk @radixark]

Today, we are thrilled to officially launch RadixArk with $100M in Seed funding at a $400M valuation. The round was led by @Accel and co-led by @sparkcapital.

RadixArk exists to make frontier AI infrastructure open and accessible to everyone. Today, the systems behind the most capable AI models are concentrated in a small number of companies. As a result, most AI teams are forced to rebuild training and inference stacks from scratch, duplicating the same infrastructure work instead of focusing on new models, products, and ideas.

RadixArk was founded to change that. We are building an AI platform that makes it easier for teams to train and serve the best models at scale.

RadixArk comes from the open-source community. We started with SGLang, where many of us are core developers and maintainers, and expanded our work to Miles for large-scale RL and post-training. We will continue contributing to both projects and working with the community to make them the strongest open-source infrastructure foundations for frontier AI.

We would like to thank our long-term partners, contributors, and the broader SGLang community for believing in this mission. We're also grateful to @Accel and @sparkcapital, NVentures (Venture capital arm of @nvidia), Salience Capital, A&E Investment, @HOFCapital, @walden_catalyst, @AMD, LDVP, WTT Fubon Family, @MediaTek, Vocal Ventures, @Sky9Capital and our angel investors @ibab, @LipBuTan1, Hock Tan, @johnschulman2, @soumithchintala, @lilianweng, @oliveur, @Thom_Wolf, @LiamFedus, @robertnishihara, @ericzelikman, @OfficialLoganK, and @multiply_matrix among others.

Thanks for the exclusive interview with @MeghanBobrowsky at @WSJ about our vision.

[HOF Capital @HOFCapital]

Today, we're proud to announce that HOF Capital is leading a consortium to acquire Porsche's stakes in both Bugatti Rimac and Rimac Group. Upon completion, Rimac Group will assume control of Bugatti Rimac, and HOF Capital will join Rimac Group as its largest shareholder alongside Mate Rimac.

We first invested in Rimac in 2022, drawn to what Mate had built from a garage in Croatia into one of the most technically ambitious companies in the automotive industry: home to record-setting hypercars, a Tier-1 supplier of batteries trusted by leading global automakers, and, since 2021, the iconic Bugatti brand. Our conviction in Mate and his team has only deepened since.

We're honored to partner with him on the next chapter, one we believe will further cement Bugatti's place as an n-of-1 company for generations to come.

@oatay @dtsao @BillionToOneInc Read the full story on how the BillionToOne team’s conviction, determination, and “20-Mile March” mindset enabled them to build what we believe to be one of the most exciting molecular diagnostics companies of our time: https://t.co/tSd9n43Nuf

[HOF Capital @HOFCapital]

Six years ago, we met Oguzhan Atay (@oatay), David Tsao (@dtsao), and the rest of the small, relentless team at @BillionToOneInc for the very first time. What stood out to us wasn’t just their promising technology or their exceptional talent; it was also their unwavering drive to accomplish a potentially world-changing mission: make precise, personalized healthcare accessible to all.

Today, BillionToOne is making its public debut on the @NasdaqExchange under the ticker BLLN.

We’re proud to have partnered with Oguzhan, David, and the rest of the BillionToOne team since the early days of their extraordinary journey.
