You want differentiated new products that will induce enthusiastic customers to open their wallets wider. Differentiated products must be… different. But different from what, in what ways, and to what extent? 100% of this information can be learned from B2B customers… but only if you engage them in specific discussions. Very few suppliers do this correctly.
Customers only pay a higher price for your innovation if it is important, measurable, and distinctive. The customer must a) care about the outcome being improved, b) observe the improvement so you get credit for it, and c) be unable to get the same improvement from your competitors. Sorry, but you need all three.
