Saas metrics are in abundance when it comes to qualifying leads or potential customers. Various analogies are taken into account like ticket size, effort to move to the platform.
In the early days of product development and onboarding customers, my learning has been different. Customers or teams who are empathetic with you during the trial period, who cares for you are the ones who will stick as customers. Focus on working closely with such team, customers, and fire the ones who do not qualify this category.
Early days of product development needs believers, not customers. They are also entitled to an early adopters program and discounted pricing.
You can onboard others as a customer with face value price when you are out for business and delight them with your service.
