CoreWeave has announced a strategic partnership with Poolside AI to deliver advanced cloud infrastructure for large-scale foundation model training and deployment. The agreement includes provisioning more than 40,000 NVIDIA GB300 NVL72 GPUs and establishing CoreWeave as the anchor tenant and operational partner for Poolside’s Project Horizon—a 2-gigawatt (GW) AI campus under development in West Texas. The first phase will deliver 250 MW of capacity, with expansion options up to 750 MW.
Poolside aims to build artificial general intelligence (AGI) and enterprise-grade AI agents capable of autonomous reasoning and code generation. By pairing CoreWeave’s GPU clusters with reinforcement learning and model-training frameworks, Poolside intends to train multi-trillion-parameter models. “To compete at the frontier you need to be vertically integrated from dirt to intelligence,” said Eiso Kant, Poolside’s co-founder and co-CEO.
Founded in 2023 by Eiso Kant and Jason Warner (former GitHub CTO), Poolside is developing AI systems designed to accelerate software engineering, enabling machines to “write software that writes software.” The company operates with research centers in Paris and San Francisco, supported by major venture capital and strategic investors. Project Horizon in West Texas reflects Poolside’s push toward self-sufficient AI infrastructure—combining on-site renewable generation with high-density GPU computing to support large-scale reinforcement learning experiments.
• CoreWeave to supply over 40,000 NVIDIA GB300 NVL72 GPUs
• Partnership centers on Project Horizon, a 2 GW West Texas AI campus
• Phase 1: 250 MW operational, scalable to 750 MW total
• Poolside founded 2023 by Eiso Kant and Jason Warner (ex-GitHub CTO)
• Focus: training multi-trillion-parameter models and autonomous AI agents
“Poolside’s approach to foundation models represents exactly the kind of breakthrough work the CoreWeave platform was designed to accelerate,” said Michael Intrator, CoreWeave’s CEO.
🌐 Analysis: Poolside has quickly emerged as one of the most ambitious foundation model startups, positioning itself alongside frontier labs such as OpenAI, Anthropic, and xAI. Its Project Horizon site underscores a shift toward vertically integrated AI infrastructure—owning the land, power, and compute stack to control training economics. With CoreWeave as both infrastructure partner and anchor tenant, Poolside gains early access to GB300 clusters and reinforcement learning pipelines essential for multi-trillion-parameter experimentation. The partnership also highlights CoreWeave’s accelerating role as the GPU backbone for independent AI labs beyond the hyperscalers.
The company was co-founded by Jason Warner (CEO), formerly CTO of GitHub—where he worked on Copilot, Actions, etc.—and Eiso Kant (CTO), an entrepreneur in AI-for-code domains (formerly of Source{d}). Warner and Kant lead a team of applied researchers, engineers, and domain experts.
Financially, Poolside closed a $500 million Series B round in October 2024 (led by Bain Capital Ventures, with participation from NVIDIA, eBay, DST, Citi Ventures, and others) valuing it at about $3 billion at that time.
