Designing a product and bringing one to market are two very different things. While things like Kickstarter have certainly began to blur that line, traditionally it takes a hell of a lot of people all with different expertise/interests to bring a product to market.
From the little information provided, my recommendation would be to concentrate on marketing. A background in finance and an interest in product design / consumer empathy (assuming you possess this?) could make a nice combo for a marketer. Don’t overestimate the role a designer has in the product development process - it is often limited and very focused, despite what most designers like to think. If you are interested in the managing a P&L, determining pricing and sales mix, allocating advertising spend, etc. then trust me, an industrial design degree will most likely disappoint.
