Mentors give advice. Sponsors give promotions.
For when: you have people who help you think, but nobody who speaks for you when it counts.
Tilen Višnjevec · Finance director, Copenhagen · Companies love mentoring programmes, and they are useful. But I have never seen anyone promoted because of their mentor. I have seen many people promoted because of a sponsor, and most of them did not know the word.
A mentor is someone who helps you think. You go to them with a problem and leave with a better view of it. A sponsor is someone senior who, when your name comes up in a room you are not in, says “yes, her, I have seen her work.” You cannot see them do it. You only see the result.
Why sponsors matter more than you think
Go back to the first post. The room decides on impressions, and the strongest impression is a senior person vouching for you unprompted. One sentence from a respected director outweighs five from your manager, because the room assumes your manager is biased and the director is not.
A sponsor also hears things you don't. If someone raises a doubt about you, your sponsor can answer it on the spot. Without one, the doubt sits there until the next cycle.
You cannot ask for a sponsor
This is what makes sponsorship different from mentoring. You can ask someone to mentor you and they will probably say yes. If you ask someone to sponsor you, you have asked them to put their reputation behind a person they have not seen enough of. The honest answer is no.
Sponsors are earned by being seen. Specifically, by senior people seeing you do something difficult well. That means getting onto the projects they care about, presenting your own work to them, and being the person who answers their question with a number rather than a promise to find out.
How it usually starts
In my experience it starts with one piece of work. A director asks a question, you give a clear answer with evidence, and they remember. Next time they need something in your area, they ask for you. After the third time, they are your sponsor, and neither of you ever said the word.
So the practical move is not “find a sponsor”. It is “do visible work in front of people who could become one, and make it easy for them to come back.”
What to do this week
List three senior people whose opinion counts in your promotion. Ask your manager if you are not sure (question four, earlier in the series).
Find one thing each of them cares about that touches your work. A number they ask for, a problem they mention, a project they sponsor.
Get in front of one of them with real work this quarter. Not a coffee. A result.
My first sponsor was a senior leader who saw a piece of analysis I presented in a meeting I almost wasn't invited to. After that, they started asking for me by name.
Mentors help you prepare. Sponsors are in the room.
