Business Outlook
Pros
Tackling long-duration energy storage for decarbonization, employees feel they’re doing meaningful work. High talent density, especially in engineering and science. Good for people who like ambiguity and building from scratch. Well-funded with high-profile investors. Tech is novel, which gives a sense of working on something unique.
Cons
Expectations are high; urgency culture can burn people out. Salary is often below big-tech, equity upside uncertain.
