Antares is building mass-producible, inherently safe, deployable microreactors for terrestrial, underwater, and space applications, with a mission to make clean energy abundant from Earth to the Asteroid Belt.

- Building financial models for major strategic decisions across manufacturing, reactor deployments, pricing, capital investment, and growth
- Developing reactor unit economics, cost curves, margin analysis, and production scaling models
- Evaluating government and commercial contracts for program economics, milestone structures, profitability, cash requirements, and return profiles
