No, I'm using Trello and GitHub Issues in my own company and I haven't any major gripes with those. For larger projects, especially in software development, I usually recommend JIRA. It might seem a bit intimidating and process-heavy but it's very flexible and works well with agile processes, too. My general recommendation would be keeping it simple for as long as you can (i.e. Trello, GitHub or the like). If your organization has grown beyond those simple means both Basecamp and JIRA are good options (the former being more on the opinionated side, the latter offering a lot more flexibility). That said, given the myriad of project management options I can't think of any reason to build yet another project management tool. You say Basecamp doesn't exactly work for you. What's so wrong with it that makes you want to develop another tool (Which is no small endeavour by the way. It took 37signals literally a decade to get Basecamp to where it's right now.)?
