The PLG sales cycle begins from the moment when your trial user lands on your product.
That’s the moment when you need to be able to track their moves through your product.
As I already mentioned, PLG sales are based on user experiences and in-app events. So, PLG sales are product-first. Having good UX/UI is mandatory.
The ultimate goal of PLG sales is to motivate your users to use your product, unleash the value as soon as possible, and convert your users to power-users (i.e. users who can’t live without your product — just like Slack did).
