“I AM A FEMINIST.”

As a professor of management at the Wharton University of Pennsylvania and the founder of both the Wharton Leadership Program and the Work/Life Integration Program, Stew Friedman has had decades to observe and study men and women in business.

One conclusion he’s made is that he’s definitely a feminist.

“I don’t understand why anyone in modern society wouldn’t want to think of themselves as wanting to support the advancement of women,” he says, “so it’s sort of a joke to me that there is a controversy about the term.”

And more and more men are joining him. When Emma Watson introduced the UN Women’s campaign He for She last September, many of us watched her speech and thought, finally. Finally, a global call to action. Finally, an appeal to men that articulated so well why gender inequality is their problem, has always been their problem, and will take 100% of the world’s population to counteract.

Gerardo Porteny was a youth engagement consultant for He for She until he returned to his undergrad studies at NYU in December. He also co-founded the organization Young Minds For Gender Equality.

“As a social entrepreneur my job is to see what is not there,” he says, and in this case, it’s the billions of men who could be acting as allies to women but don’t feel connected to feminism. So, he joined the movement and created YM4GE.

Gerardo sees the rise of female entrepreneurship around the world as cause for celebration: “There is not a greater tool for empowerment than entrepreneurship. I’ve personally seen how my mother’s entrepreneurship venture has given jobs and provided life enhancement to both men and women.”

The follow-up to Facebook COO Sheryl Sandberg’s massively popular book Lean In is another example of the growing momentum among men who want to act as allies. Sandberg launched #LeanInTogether, a campaign that recognizes that while women can definitely take steps to move up in the corporate world – or to get their start-up off the ground – they can’t do it without the support of the other half of the population. It gives men the tools to support women in business, starting with a list of ‘tips for men at work.’

The list includes tips like “get the most out of meetings,” encouraging men to make sure women’s voices are heard in the boardroom since, “compared to women, men tend to talk more and make more suggestions in meetings, while women are interrupted more, given less credit for their ideas, and have less overall influence.” Not only is correcting this problem a great step toward being an ally, it means tapping into the team’s full potential and insight.

But challenging sexism doesn’t stop when men leave work. #LeanInTogether also encourages men to take their activism home by sharing housework and being active examples of equality for their children.

This is particularly important since, for many women, limits on their dreams can be traced back to childhood where seeing gender roles played out by their parents had a profound effect on how they envisioned their own futures.

A 2014 study backs this up. Researchers surveyed more than 300 children and found that when fathers took on their fair share of housework, their daughters took a greater interest in either working outside the home or in jobs that weren’t traditionally feminized.

And if that isn’t reason enough to be an ally, another study that came out last January found that men who share family responsibilities and spend more time with their children are happier at work. They report less work-family conflict and are less likely to consider quitting their jobs.

So let’s recap: men who act as allies to women have more productive businesses, happier families, more ambitious children, and are happier in their own career paths. What is there to lose?

On the Dream, Girl crew, Sal Mastrocola is a great example of someone who acts as an ally in both his personal and professional lives: along with being the film’s musical composer, he’s director Erin Bagwell’s husband and biggest fan.

To him, being a part of Dream, Girl means “truly, the world.”

“Every day of the last 3 years has been an adventure. To see Erin go from a series of corporate jobs where she wasn’t being given the chance to achieve her full potential to this exciting, unexplored world on the path to her dreams has been so rewarding and awe-inspiring.”

His advice for men who want to support the rise of women-led start-ups? “Female entrepreneurs are the real deal. Treat them as such.”

And that’s what it all comes down to: as long as men continue to treat their colleagues, partners, and daughters with equal respect, we’re all uplifted allies, as feminists, and in life.
