Any SaaS B2B company with network effects does this easily because the revenue from each customer is a function of the value they derive from the software, which increases with the square of the number of customers.

Think Excel (network effects derived from its communication properties), CoreLogic (derived from having all the data), Addepar, etc.

These companies also typically have high fixed costs across all of their customers once they are at scale.
