# Critical Loop

> Critical Loop is an industrial power company founded in 2023 by former SpaceX, Tesla and Palantir engineers. It deploys modular, relocatable battery-storage microgrids - paired with its software-defined controller, Cygnus - to give factories, data centers, airports and other grid-constrained sites reliable power in weeks instead of waiting years for utility upgrades. The company raised a $26M Series A in April 2026, bringing total committed funding to $49M, and operates a fleet of control nodes across California.

- **Founded:** 2023
- **Headquarters:** Long Beach, California, United States
- **Founders:** Balachandar Ramamurthy (Co-Founder & CEO (former SpaceX flight-safety chief engineer / human-rated Falcon 9 lead)), Lydia Maher (Co-Founder & CTO), Andrew Grinalds (Co-Founder & COO)
- **Team size:** ~41 employees; engineers and operators from SpaceX, Tesla, Palantir and Rivian
- **Products:** Cygnus, CLB-5100, Microgrid cabinet / combiner, On-demand power (flexible service agreements), Long-term power infrastructure
- **Notable:** Raised $26M Series A in April 2026; $49M total committed funding., Deployed ~50 MWh of storage and 67 active control nodes across California., Cited by the California Public Utilities Commission in a February 2026 rulemaking requiring SCE and PG&E to offer flexible service connection options.

## Products & services

- **Cygnus** — A compact, hardware-agnostic, software-defined power controller that autonomously monitors the grid, pulls maximum available power, and switches between batteries, generators and other distributed energy resources whether on-grid or off-grid.
- **CLB-5100** — A 1 MW relocatable battery system that combines storage, flexible generation and Cygnus control into a single deployable, modular platform for grid-constrained sites.
- **Microgrid cabinet / combiner** — Equipment that integrates diverse power sources - multiple battery types, grid connections and on-site generation - without custom adaptation, orchestrated remotely in real time.
- **On-demand power (flexible service agreements)** — Temporary and bridging power delivered through flexible agreements for outages, construction, film production, EV charging and load expansion.
- **Long-term power infrastructure** — Design, development, implementation and maintenance of behind-the-meter battery infrastructure for industrial facilities, with remote orchestration and load flexibility programs.

## Achievements

- Raised $26M Series A in April 2026; $49M total committed funding.
- Deployed ~50 MWh of storage and 67 active control nodes across California.
