Ask HN: Getting the attention of a much larger potential partner

How do you go about getting the attention of a much larger potential partner, especially if that partner is in the consumer space where product people tend to be hidden behind layers of customer service and other walls. We aren't in a position to interest a biz dev team, since there's no money ready to change hands, but I'd really like to build a relationship with the product management teams of the products we are basing our future on.
