As entrepreneur freebies are a good way to attract people. Hence I would recommend - Differentiate between your core products and side products. Much like what WinRAR did, There customers were both corporates as well as personal users. They made the software freely available to private users to avoid piracy and increase adaptability while targeting the Corporates for revenue that drove their business. The Freebie model was useful for them. The same cases are used by other companies where one product drives the profit while other products are there to attract customers. I can help you more if you can tell me more about your business.
