Overview
Austin-based power developer founded in 2024 by Ben Longmier and Sara Spangelo, previously of Swarm and SpaceX's Starlink Mobile team. It develops off-grid solar-plus-battery projects for large electricity customers. Ambrosia describes a West Texas project designed for 200 MW of solar and about 20 MW of continuous output.
Why Ambrosia Energy is interesting
Ambrosia's promised rapid deployment targets a bottleneck in data-center and industrial growth: the long wait for grid capacity. Its economics and delivery timetable remain company targets, not independently proven fleet-wide results.
Product & use cases
Ambrosia develops, finances and operates solar-plus-battery installations for customers with urgent and sustained electricity demand, providing an alternative to waiting years for transmission and utility interconnection. The 200 MW solar and 20 MW continuous-power figures describe project design, not audited commercial production.
- New industrial sites and data-center projects awaiting grid upgrades
- Large customers seeking predictable on-site electricity supply
- Locations where grid interconnection queues create multi-year delays
Key facts
- Founded by Ben Longmier and Sara Spangelo after their work on Swarm and Starlink Mobile.
- A June 2026 company update described the first operating sections of a West Texas power project, with further construction funded.
- Company targets include power delivery around 12 months after contracting and pricing near $100/MWh; these are claims, not guaranteed terms.
- a16z selected Ambrosia for its 2026 American Dynamism 50, Inputs pillar; inclusion is not proof of a16z investment.
Competitive landscape
Edge: Integrated project development and a team with previous spacecraft-communications experience; execution risk, utilization, storage duration and the actual delivered power price still require independent validation.
Differentiate Ambrosia's claimed speed-to-power and around-the-clock contracted output from standalone solar nameplate capacity. Do not equate 200 MW solar installed with 200 MW continuous supply.
