About Posh

GPAgent's own fund-neutral profile, written from public information. Updated Oct 5, 2026.

Summary

Posh develops data center projects for AI compute customers by building power supply and site infrastructure together. It selects buildings with existing electrical plant, then layers in grid power, on-site generation (fuel cells, solar, flex-fuel), and storage, coordinated through AI-driven dispatch. This replaces the conventional sequence of designing a data center first and solving for power later, compressing the time to bring capacity online.

Business model

Project development fees and energy delivery contracts on a per-site basis.

Go-to-market

Posh targets commercial and industrial customers building AI data center capacity, engaging them through direct project discussions with a combined development and energy team.
