Professional women receive endless advice. Yet they remain underrepresented in leadership roles.

I’ve watched this pattern repeat across industries, companies, and continents. Talented women collect mentors. They implement feedback. They refine their leadership style, their communication, their executive presence. Performance reviews stay strong. Promotions still go elsewhere.

Mentorship has value. It provides guidance, perspective, and skill development. But here’s what mentorship lacks: the ability to put your name forward when you’re not in the room.

That’s where sponsorship comes in.

Mentorship provides guidance and skill development. Sponsorship opens doors to real opportunities.

A mentor helps you prepare for the next opportunity. A sponsor creates the opportunity and ensures you’re considered for it. Sponsors actively advocate for you in rooms where decisions get made.

The distinction sounds simple. The impact is massive.

Research shows that women with sponsors are 167% more likely to receive high-profile, stretch assignments. These are the projects that demonstrate readiness for executive roles. The ones with bigger budgets, higher visibility, and direct access to C-suite leaders.

Without a sponsor advocating for you, those assignments go to someone else. Usually someone who looks like the person making the decision.

Here’s the reality: only 23% of employees report having a sponsor in the workplace.

That means 77% of professionals are trying to advance without anyone actively fighting for them in decision-making rooms. They’re working hard, delivering results, and hoping someone notices.

Hope is not a strategy.

The gap hits women harder because of how sponsorship relationships typically form. Sponsors tend to advocate for people who remind them of themselves. When 70% of C-suite executives are men, that pattern perpetuates itself. Women receive mentorship while men receive sponsorship.

Advocacy remains limited despite abundant advice.

What makes this worse is that organisations are pulling back from the programmes that could help.

Formal sponsorship programmes tailored to women dropped from 31% in 2017 to just 16% in 2024. That’s nearly a 50% decline in seven years.

Companies are cutting these initiatives at precisely the moment when women need them most to break into senior leadership. Gender balance in leadership remains a low priority for sustained investment.

Meanwhile, the representation numbers tell the story. Women make up 51% of individual contributors but only 30% of C-suite roles. The drop happens in the middle, where sponsorship matters most.

Sponsorship involves four key actions: amplifying achievements to decision-makers, recommending people for high-visibility projects, connecting them to influential leaders, and defending them against biassed evaluations.

It requires someone with power to spend their credibility on you.

That’s why sponsorship feels scarce. It demands risk. A sponsor’s reputation is on the line when they advocate for someone. They’re saying, “I believe this person is ready, and I’m willing to stake my judgement on it.”

Sponsorship requires significant personal investment. Leaders can mentor many people, yet genuinely sponsor only a few.

This scarcity increases both the value and the consequences of limited access.

If you’re a woman trying to advance into leadership, ask yourself: who is fighting for you in rooms where you’re not present?

Without that advocacy, mentorship alone cannot close the gap.

If you’re a leader with influence, ask yourself: who are you actively sponsoring? Are you recommending women for stretch assignments? Are you advocating for them in promotion discussions? Are you using your credibility to open doors?

The gender gap in leadership requires people with power to use it differently. Advice alone cannot drive this change.

Doors open from the inside. Sponsorship is how you get someone to unlock them for you.
