What,if any, is the difference between platform and solution marketing? How do you approach messaging and customer segmentation?

Platform Marketing is an extension of traditional product marketing. Instead of owning a single product or capability,  Platform Marketers are responsible for bringing connected platforms or horizontal capabilities like data infrastructure, AI, or 3rd party integrations to market. Solution Marketing is the art of understanding the problems of different types of users, personas, or industries your product or service can solve and translating that into use case messaging that informs marketing and sales enablement. Solution Marketers are often Platform marketers because instead of a single product capability, they own Personas, Industries, or Verticals and have to tell stories about how their persona or group uses the entire platform. Product Marketers, Platform Marketers, and Solution Marketers are all responsible for the traditional elements of Product Marketing: Messaging/positioning, product launches, pricing/packaging, competitive intelligence, go-to-market/enablement, etc. Solution Marketing can be the responsibility of a PMM/Platform Marketer, or a dedicated Solution Marketer can work with these teams and focus more on the go-to-market side of PMM as persona subject matter experts.
