Some customers might want to use Ideas, but not use the rest of the product. I only want to pay for what I will use. :)
Thank you for the request. There is no doubt that we offer a premium product. If you have used Aha! and other tools -- I think you will agree that there is no comparison. Aha! is designed to help product managers focus on the Why, the When, and the What of building great products. Capturing ideas in a central place is important but Aha! is also intended to help you evaluate those ideas against your strategy and connect work back to the strategy for ideas that get promoted.
At this time, we do not have plans to separate these activities into an ideas only plan. We hope you can understand.
