Engage customers who have contributed to your product roadmap by following up with them when features they requested are released.
It can be frustrating for customers to share ideas and not get anything in return. If customers don't feel heard, they will go elsewhere. Following up with customers who have contributed to your product roadmap is a great way to show them that their ideas are valued and appreciated. You can do this by sending them a personal email when you release a feature they have interacted with in the roadmap. You can also give them beta access to those features and try to get feedback from them. At StatusPage.io, they track customer feature requests in a Google spreadsheet. When a user makes a request, they log it in the spreadsheet and get on the phone to chat with the customer as appropriate. When the feature is built, they reach back out the customer to tell them about the feature. This method has been used to grow their annual recurring revenue from $0 to $2.49M and it drove upgrades which increased their average revenue per customer by 2.4x.
