I worked for a company 15 years ago that had build a nice collaboration website like Confluence/Jira for internal use. It was built by an internal team of 5 engineers. Very nicely done UI. The company had a lot of things going for it but it missed a few strategy opportunities and was bought for a song and split up. In hindsight, I feel like that collaboration software could have been a business of its own but nobody recognized it. Maybe 10 years too early.
