Jump’s work has elements of management consulting and a bit of design-firm draftsmanship, but its specialty is conceiving new businesses, and what it sells is really the art of innovation. The company is built on the premise that creative thinking is a kind of expertise. Like P.&G. and Mars, you can hire Jump to think on your behalf, for somewhere between $200,000 to $500,000 a month, depending on the complexity and ambiguity of the question you need answered. Or you can ask Jump to teach your corporation how to generate better ideas on its own; Jump imparts that expertise in one- and five-day how-to-brainstorm training sessions that can cost $200,000 for a one-day session for 25 employees.
