Talk about what they want to be good at.
Think of ways to help them succeed. Talk about what they care about. Let them know you understand how important those things are. Then show them you understand what contributes to their success in those areas. Then, talk about how what you do makes those things happen faster, cheaper, easier, better.
Once they trust you to help them achieve those things, help them share this vision with their peers and bosses. They probably won’t ask for your help here. Nobody wants to say “I don’t have enough influence.” But they probably need your help. Find ways to offer it before they need it.
