Probably spend a lot of time working out who your company's customers are, what problem they want you to solve and how the company is currently performing at doing that. This can be done together with different people, for example the customers themselves, your sales team, your PM team, customer support team, operations, executives, etc. so that you build up a bit of a network internally. This should give you some good background knowledge for developing your product strategy.
