Understand the Users and not just the Buyers
You obviously need to chart a buyer persona while selling your product, but you also need a user persona. What you're pitching and selling must appeal to both. Ones who make the decision to purchase and ones who actually use the product regularly.
Your user persona will consist of distinct characteristics, wants, and goals of people who will be using your product everyday.
Whereas your buyer persona will be a broader bio of your target customers - this can include influencers or decision-makers across a company who’ll make the purchase decision.
Keep in mind how both of them can easily influence each other’s decisions to purchase or not to purchase. To upgrade or not to upgrade.
