Infrastructure for the Autonomous Era · First in. First up.

--------------------------------------------------- MESH stores its energy in batteries, and that energy has to be safe, measured, and ready on demand. You own the pack and the brains that keep it that way, from cell selection to a system that charges, discharges, and protects itself in the field. In a power-storage product, this is core IP, and it is yours.

First Order Effects (FOE) is building America's Infrastructure Prime for the robotic era. Autonomous ships, drones, and robots are rewriting how the world moves, fights, and builds - but none of them work without infrastructure to power them, connect them, and launch and recover them. That's what we build.

Our team comes from SpaceX, Anduril, Saronic, Lockheed Skunk Works, Forterra, and Fuse Energy. Before founding FOE, we built satellite ground stations that closed a national comms gap in days, deployed multi-megawatt power systems at commercial speed, and shipped autonomous surface vessels into Navy fleet production. We've built infrastructure at lightspeed before - now we're applying that playbook to an entire company.

Own the LFP battery system: pack architecture, cell selection and sourcing, mechanical and thermal design, and integration into MESH.

Own the BMS: cell monitoring, balancing, protection, contactor control, and state estimation.

Define battery safety: fault detection, isolation, and the response that keeps energy contained.

Work with power electronics and firmware on charge, discharge, and power dispatch.
