Product marketers can get bogged down in identifying endless lists of product benefits, each slightly different for different customer segments.
There is a problem with this for potential buyers of a product. The long list of benefits waters down what is truly unique about your product. All benefits sound exactly the same as the benefits that are being claimed by about every company in the world.
There is also a problem with potential investors in your company. Investors are interested in buying your company, not your product, so the scope is broader than product benefits. Also, they are buying into someone who is hopefully able to sell. "If I were a potential client, would I buy this product pitch?"
