Absolutely the greatest company to impact the environment through transportation
Pros
The work done at CALSTART is enacted in the real-world. All white papers are used in the transportation sector to create new products, influence policy, and create new operational methods. Projects are very rarely "repeat" projects, unlike other consulting firms. This work is for problem solvers, not order takers. The work has a visible impact, you see what you create, and you get to work with passionate, motivated, intelligent people every day.
Cons
Having been around for 30 years, CALSTART has more experience in alt fuel and zero-emission technology than any other firm. They were working in the field before it was fashionable, funded, and trend setting. This means the industry leans more heavily on that type of expertise. There is a lot of work, and it can be hard to stay on top of it all.
