Phoenix is the capital of the Arizona office space market and the largest city in the state. It is also the fifth largest city in the country and home to some of the USA’s largest companies, including PetSmart, Intel, Boeing, American Express and more. Economic opportunities abound in this desert metropolis, and the city is also a center of arts and culture that includes museums, botanical gardens and the largest municipal park in the world. With a young, educated population that is multicultural and upwardly mobile, any startup would do well to choose Phoenix as its home. There is also some great office space for rent in Tucson.
