Margaret Molloy 🙋‍♀️

Board member and three-time Chief Marketing Officer with deep experience in enterprise brand building, strategic marketing, and executive convening. I’m an operator who harnesses the power of networks, designing gatherings and platforms that deepen relationships, strengthen brands, and unlock growth.

Trusted for simplicity, substance, and a global network.

I work with founders, boards, and executive teams seeking brand building, elevated convening, and go-to-market expertise. A LinkedIn Top Voice and media contributor, I’m known for discernment, strong moderation, and a track record connecting brand building to demand generation and commercial impact.

I curate and facilitate roundtables and salons that bring senior leaders together with intention. As CMO of Siegel+Gale, I recruited and interviewed hundreds of CMOs for our award-winning Future of Branding series and the How CMOs Commit podcast, combining a marketer’s fluency in audience engagement with an owner's entrepreneurial passion.

With in-house leadership experience spanning Siegel+Gale / Omnicom, GLG, and Siebel Systems (Oracle), and over a decade working with agencies and senior executives globally, I understand how disciplined brand systems and artful convening shape long-term business impact.

How I Work:
As a CMO, I build marketing teams that grow pride, profile, and profit.
As a board member, I provide a marketing lens, an instinct for simplification, and a commitment to sustainable growth.
As a host, I create environments where people think sharply and connect easily.
As a coach, I guide leaders on personal brand, LinkedIn, and network strategy.
As a content creator, I help brands reach executive audiences through storytelling.
As a connector, I introduce trusted people with purpose and personalization.

Approach and Beliefs:

• Networks compound when built with intention.
• Simplicity and connection sit at the heart of strong brands.
• Elegance is not decoration; simplicity is its highest expression.
• Execution is the ultimate differentiator; it requires systems, discipline, and stakeholder partnership.
• Staying close to youth through guest lecturing keeps my perspective fresh.

That’s backwards.

I know, some people don’t even like the word network.
It can sound transactional. I get it. 
And any comparison of people to assets can be off-putting. Also, I get it. Truly.
Yet I find the frame can be helpful to sit with.

Over the course of my career, I’ve learned something simple:
The biggest opportunities rarely come from the best strategy or the perfect timing.
They come from people.

The asset that shapes our careers and our businesses the most often gets no strategy at all.

Our relationships.

If you treated relationships with the same care you give your investments, you might ask:

↳Where have I let connections go quiet?
↳Is my circle too narrow or too familiar?
↳Where do I need more diversity of thought, industry, or lived experience?
↳Who stretches my thinking?
↳Who am I investing in without expecting anything in return?
↳Who can I get advice from to grow my relationships?
↳What tools can I use to build my relationships?

Networks compound.
↳Through introductions.
↳Through trust.
↳Through people speaking your name when you’re not in the room.

This time of year is a good moment to rebalance.

As a strategic, business-minded B2B marketer, I drive innovative strategies that grow company profit, profile, and pride. Said simply, “marketing is in my DNA”—an unexpected statement from a farmer’s daughter and immigrant, but it was on my family’s dairy farm in Ireland where I learned the value of hard work, keeping promises, and a commitment to community and connection—the same values that are essential to top-performing brands and businesses. This drive for community, the sense of wonder, and the industrious operator work ethic gained in my youth continue to serve me well, allowing me to mobilize inclusive marketing teams across diverse industries, from tech to professional services to agencies. With critical thinking and leadership experience across every marketing discipline, I unite brand building with demand generation and bring an unwavering focus on sales and marketing alignment. Most of all, I hire talented people, coach and empower them to be their best.

I am a simplifier. I study deeply to explain simply. Now, with over two decades in marketing and as the Global CMO for Siegel+Gale, I help cut through the noise and underscore the insights that drive business results. I connect my expertise with intentional questions, moderating panels, contributing articles to top publications, and hosting the “How CMOs Commit" podcast, featuring the world’s top CMOs. Always cognizant and proud of my Irish heritage, I am also the creator of the movement and blog #WearingIrish, where I celebrate talented Irish fashion designers and their creations.
