They all started simple then went upmarket. Salesforce.com started by selling a handful of users at $50 a user. Within three years, they were selling deals of 1,000 users at $125 a user. Then a few year later, tens of thousands of users at $300 a user (list price). Salesforce.com put tremendous focus on selling (and delivering) deals with massive user counts, while finding ways to create higher end packages… which combined to create massive revenue acceleration.
