Jackie Cook is the Founder and CEO of Momentum Group, where she helps leaders and founders navigate what’s next, whether that means a career transition, a leadership challenge, AI adoption, or meaningful business change.
Her work is built around a reality she has experienced throughout her career: the moments that require the most from us rarely arrive with a clear playbook. A new role. A career transition. Building something from scratch. Leading through change. Figuring out where AI belongs in the work. These moments require more than information. They require clarity, judgment, and the confidence to move.
Rather than simply telling people what they should do, Jackie focuses on strengthening how they think, decide, and navigate forward when the path is not obvious.
With more than 20 years of experience across product, strategy, operations, organizational transformation, and leadership, Jackie has built her career at the intersection of business performance and the human experience of change. She has led enterprise initiatives at organizations including Mercer and Marsh McLennan, helping align strategy, scale teams, improve operations, and translate complex business priorities into meaningful results.
That experience shaped the philosophy behind Momentum Group. Jackie saw firsthand that highly capable people often struggle during periods of change not because they lack talent or ambition, but because complexity makes it difficult to see what matters, determine what comes next, and move with intention.
Momentum Group was built for those moments.
Today, Jackie works across career navigation, leadership, business transformation, and AI. Through advisory work, leadership experiences, decision frameworks, and a growing portfolio of AI-enabled tools and platforms, Momentum Group helps individuals and organizations turn complexity into clearer direction and practical action.
Across that work, the goal remains the same: create the space and structure for better thinking, strengthen judgment, and help people move from uncertainty into meaningful forward momentum.
Jackie holds a Bachelor of Arts in Psychology and a Bachelor of Science in Organizational Leadership from Penn State University. She has continued her executive education across areas including design thinking, artificial intelligence, business strategy, and finance.
She is also actively engaged in philanthropic and community leadership, using her platform to elevate others, create connections, and expand access to opportunities.
Jackie’s work is grounded in a simple belief: people rarely need more information. They need the clarity and judgment to know what matters, decide what comes next, and move.
Her Interview
01What do you attribute your success to?
I attribute my success to my ability to operate across strategy, operations, and leadership while staying grounded in how people actually experience change.
But more importantly, I learned early that clarity is a leadership responsibility.
In fast-moving environments, most people wait for clarity before they act. The leaders who stand out are the ones who know how to create it.
That requires a willingness to sit in uncertainty, challenge your own assumptions, and make decisions before everything feels fully formed.
That shift has shaped how I make decisions, how I lead teams, and ultimately how I built Momentum Group around helping others do the same.
02What’s the best career advice you’ve ever received?
One of the most impactful pieces of advice I received early in my career was a simple question: “What’s your point?”
At the time, it pushed me to be more intentional in how I communicated. Over time, it became something much bigger.
It taught me that clarity is not just about what you say, but how you think. When you are clear on your point, you make better decisions, communicate more effectively, and help others move forward with confidence.
That lesson has stayed with me throughout my career and continues to shape how I lead today. In many ways, it sits at the core of my work now, helping leaders create clarity in moments where it is often missing.
03What advice would you give to young women entering your industry?
Focus less on having everything figured out and more on learning how to think clearly in motion.
It is easy to believe you need the perfect plan before you begin, but in reality, clarity often comes after you start.
Get specific about the problem you are solving and who you are solving it for. Then test, learn, and adjust quickly.
The leaders who move forward are not the ones with perfect answers. They are the ones willing to engage, make thoughtful decisions, and refine as they go.
That insight led to the founding of Momentum Group and now shapes both the advisory work and AI-enabled platforms we are building to help people navigate complexity more effectively.
04What are the biggest challenges or opportunities in your field right now?
The biggest challenge, and opportunity, in leadership right now is that leaders are being asked to make decisions in environments where complexity is increasing faster than clarity.
The volume of input has grown, especially with AI and rapidly shifting expectations, but the ability to filter, prioritize, and decide has not kept pace.
Leaders who can create clarity, exercise sound judgment, and move forward with intention will stand out.
That insight led to the founding of Momentum Group and now shapes both the advisory work and AI-enabled platforms we are building to help people navigate complexity more effectively.
05What values are most important to you in your work and personal life?
Integrity and authenticity are foundational to how I lead.
I believe leadership is not just about what you do, but how you show up, especially in moments that require trust, transparency, and consistency.
Staying grounded in those values shapes both my leadership approach and the work I do with others.
