Just want to heartily agree with this point here. Certainly many of us do get excited about particular business domains from time to time, but in my own experience, I get more excited about technical challenges, and -- critically -- solving real problems for real customers that I can see first- or nearly-first-hand. The customers for this "product" would be internal to OP's org, so the people who end up building this would have front-row seats to how it's being used, what's good, what's bad, etc.
