How does your company define the difference between Product Management and Product Marketing teams? How do the responsibilities differ?

I work at Intercom where Product Managers where closely with Product Marketing Manager ('PMM'). The four main areas that our PMMs cover are:

• Customer and marketing insight - Like PMs, our PMMs want to be as close to the customer and the market as possible. PMMs represent the voice of the customer internally.
• Product strategy - Whilst the PM is ultimately accountable for the creation and execution of the product strategy, PMMs play an important role in informing the product strategy and roadmap.
• Product positionong and messaging - PMMs develop product positioning and messaging. Naturally, PMs will feed into this, but things like positioning statements and messaging guides are owned by the product marketeers.
• Go-to-market strategy - PMMs are responsible for definining and implementing a go-to-market strategy for a product or feature. Again, PMs will work closely with the product marketeers on this, as they will have a good feel for how to launch the produc to market.

Product Management primarily partners with engineering. They are responsible for what we build, and why we built it. Product Marketing is responsibile for how we position these products to the customers. While product management is also responsible for the positioning, they are looking at it as part of the vision and decision making.
