Yup. Stack was born out of our internal build tool "fpbuild". We found that having a good build tool was crucial to our productivity. Stack was created to better satisfy our own needs, and we shared it with the community so that they can also benefit from it and help make it better.

When someone's consistently had good contributions and discussion, we've granted them maintainer level privileges. Certainly quite a lot of stack's development and maintenance is done by FP Complete folks. However, our intention is to make the project as open to contribution and feedback as possible.
