Compute, power, intelligence: Poolside goes full-stack with Project Horizon

Integrating across compute, power, and intelligence.

poolside’s path to AGI

When Air Street portfolio company poolside launched in 2023, it set out to build artificial general intelligence by mastering software development in the most demanding environments. Software, the company argued, requires reasoning, planning, and an understanding of the world. The same ingredients underpin human cognition. From the outset, poolside’s mission has been to translate those principles into systems that operate reliably and at scale, supported by infrastructure built to last.

Now that conviction takes physical form. Poolside has unveiled Project Horizon, a 2GW AI campus in West Texas designed from the ground up for multi‑agent systems. Through a partnership with CoreWeave, which will anchor and operate the first 250MW phase, poolside is combining compute, power, and intelligence under one roof to create a vertically integrated foundation for the agentic enterprise.

From data centers to AI factories: a purpose-built cloud for AI agents

As we wrote in the State of AI Report 2025, power has become the new bottleneck for AI progress as large labs compete for resources to train and serve the insatiable demand for their frontier models. Multi-GW clusters have moved from slideware to site plans, and grid constraints are beginning to shape both roadmaps and margins. What’s more, AI infrastructure has become a lever of national strategy. This means that the ability to generate, store, and apply compute power independently is a question of technological sovereignty.

Project Horizon is poolside’s answer to these challenges. It is a ground-up data center development designed to give the company long-term control over power, cost, and scale through vertical integration. The campus will be developed in eight phases of 250MW each, ensuring scalable, modular growth aligned with advances in compute demand and silicon efficiency. In doing so, poolside can commit to providing long-term access to energy, compute, and intelligence to serve the most demanding of customers.

Located in West Texas, the site sits near a major natural gas hub with access to existing water, processing, and fiber infrastructure. It occupies part of the Longfellow Ranch, whose owners, the Mitchell family, have supported Horizon’s development across their expansive property. Dual long-haul fiber routes provide high-bandwidth, low-latency connections to major network hubs, while the behind‑the‑meter design allows poolside to directly manage its power generation. The campus is engineered for modular expansion, built with redundancy at every layer of the power stack. Generation will come from efficient aero‑derivative turbines meeting strict emissions standards, supplemented by grid‑interconnect redundancy and on‑site battery storage to improve reliability and load balancing.

A milestone for poolside

For poolside, Horizon is an infrastructure milestone and a major expansion into controlling the inputs that determine who reaches the frontier. In an industry where access to energy and clusters now defines the limits of ingenuity, Horizon gives poolside direct control over the two scarcest resources in AI: power and compute. Owning this foundation means the company can train and serve frontier‑scale models on its own timeline, protect customers from the volatility of cloud pricing and availability, and invest in sustained capability growth rather than short‑term capacity.

This level of vertical integration - from model and agent development through to power generation and deployment - gives poolside a durable advantage as AI systems become indispensable to enterprise and national infrastructure alike. Project Horizon turns energy and compute from external constraints into internal levers of scale, marking poolside’s growth from an AI model builder into an industrial company of intelligence.
