Prime Intellect

Mobius Intelligence is the venture led by UC Berkeley PhD student Sijun Tan that pitched at GMI Cloud's SCALE accelerator Cohort 2, presenting the open-source rLLM project as its homepage. rLLM is a Berkeley Sky Computing Lab reinforcement-learning post-training framework for language agents that powered DeepScaleR, DeepCoder and DeepSWE. No separate company site, founding year or HQ is disclosed.

RadixArk, founded in 2025 in Palo Alto, California, USA, develops AI systems around the SGLang inference engine and Miles reinforcement learning framework, improving model inference and training efficiency by reducing compute and memory requirements.

Open-source AI compute orchestration platform unifying AI workloads across clouds, Kubernetes and GPU providers.

Aranya is a San Francisco-based AI infrastructure company building clusterdOS, an open-source Kubernetes-based multicluster operating system that automates everything from kernel drivers to cross-cluster federation, turning bare-metal servers into production-ready, self-healing AI inference and training clusters within 48 hours. Founded in 2025 by Christian Bhatia Ondaatje (ex-Crusoe, ex-Hyperbolic) with two MIT Sloan co-founders; partners include Hydra Host.

Thunder Compute is a systems research lab building GPU virtualization software, founded in 2022 and headquartered in San Francisco, and a member of Y Combinator's Summer 2024 batch. Its core technology, GPU-over-TCP, abstracts GPUs as network resources rather than bare-metal allocations, running invisibly beneath workloads to improve scheduling and utilization across data centers and partner GPU fleets. The company positions itself as VMware for GPUs and operates its own on-demand GPU cloud (per-minute billing, one-click VSCode connection) as a production testbed alongside enterprise software partnerships.

Nutanix is a hybrid multicloud infrastructure software company known for hyperconverged infrastructure. Its Nutanix Cloud Platform spans compute, storage, AHV virtualization and multicloud management, and its Nutanix Enterprise AI (formerly GPT-in-a-Box) lets enterprises deploy, fine-tune and run LLMs on-premises and at the edge. Listed on Nasdaq (NTNX) since 2016.
