What other business models would you recommend? We are still pretty new and are open to suggestions. Moreover, we are still a very small team and it's easy for us to change our business model. SaaS seemed to be the best, so we went with it.
I am a strong believer in open-source and against rental/pay-per-use, so if there is some way to work that into your product that would be cool. People should be able to buy a product and run/use it at their leisure. But don't go and kill your profitability on my account...
