Is There a Tool for Thought Project Management?

The b to d play book is the idea that you get developers to use and love something, maybe it's an open source library or a service. The best example there would actually be something like gmal. G mal far and wide with this incredibly generous free plan, and then they added the gmal for business thing. So if i was to think about this playbook, writing it for mews, it seems to me like the thing that you would want to test,. I don't actually know what the answer tha have an opinion, but one thing i wer seeing is now, we're only going to charge when the whole company starts to use this product to collaborate.
