Storytelling, bringing the customer vision to life, and having a wide variety of skillsets (I always love ex-entrepreneurs) is vital for an industry marketer to be exceptional.
The industry marketers job is to bring the buyers vision front and center. A key difference here is that product marketers are more focused on ensuring the product is the centerpiece; Its features and benefits are all around the product, not the customer. Solution marketing, which ties into industry product marketing, brings value driven messaging to life and the product is the support for the message. Messaging is around moreso what the buyer needs and wants. A good industry marketer will be able to wrap around multiple products and at times, partners, in order to package them together to effectively communicate and ellicit the needs of the buyer. Often times this leads to higher ASP per deal due to "packaging" different products around a single message.
