You’re a team. It’s great for you that one of your teammates comes up with good solutions. It helps everybody move forward.

Now you’re good at selling these ideas to the rest of the company, so just do that. Make sure you give the credit to the right people, and they’ll feel rewarded.

If you want you may give people some slightly more specific title like “lead developer” or “solution architect”. Though this may annoy some other people. You may also reward the person with higher salary (disclaimer here: I am not that person).
