Do you know any company that seriously wrote their own development IDE or project management solution comparable to Jira for internal use? That sounds like absolute madness to me. I agree though that you should never sell to developers, most of them really don't care how they spend their time as long as they are occupied and work on something they deem interesting, so they will happily spend months or years reinventing existing solutions if given the opportunity (I've seen this again and again). You need to sell to the people that run the company and pay the developers or to the engineering management, because they know how much their developers cost, and they understand ROI better than they do. That said often developers are quite creative when making up reasons why not to use an external solution or tool and instead write it themselves, so whether you succeed in selling to a company depends on who's ultimately in charge of technology.
