Large Enterprise Finalists

Jean English is the CMO at CoreWeave, where she leads the company’s global marketing and communications strategy. Throughout her career, Jean has consistently led marketing through pivotal technology shifts, from enterprise computing and hybrid cloud to cybersecurity and AI. Jean built CoreWeave’s marketing function from the ground up, establishing The Essential Cloud for AI as the company’s defining market position and helping advance CoreWeave’s leading role in the AI ecosystem.

Jean English joined CoreWeave as its first CMO 28 days before the company’s IPO, the largest US tech listing since 2021. She defined "The Essential Cloud for AI" as CoreWeave’s market position, defining the excellence its technology already delivered. That position earned CoreWeave validation from top industry analysts, a spot on TIME100’s list of influential companies, and deeper trust among the AI pioneers building on its platform (9 of the top 10 AI models rely on CoreWeave Cloud). The financial impact has followed suit: annual revenue grew to $5B, and CoreWeave recently joined the Nasdaq 100.

Kristy LoRusso leads Kaiser Permanente’s national marketing strategy, redefining health care through the power of connection and trust. Since 2007, she has transformed its storytelling capabilities, notably spearheading the "A Better Idea for Health Care" campaign, which helped earn Kaiser Permanente the #1 spot on Forbes’ "Best Brands for Value" list. Prior to her tenure in health care, Kristy held leadership roles at Yahoo!, The Walt Disney Company, Time Warner, and Primedia Publishing.

While I’m proud of milestones like helping reach diverse communities during the COVID-19 pandemic, modernizing Kaiser Permanente’s brand, and earning industry recognition, those are not the achievements I value most. My greatest impact has been the people, specifically creating a culture where everyone feels truly seen and heard. I strive to help talented individuals grow into confident leaders by giving them opportunities, support, and trust. Throughout my career, I’ve had the privilege of mentoring colleagues who have gone on to do extraordinary things, many within Kaiser Permanente. Their success is the legacy I’m most proud to have helped shape.

David McCulloch is Vice President and Chief Communications and Marketing Officer for Pacific Gas and Electric Company, leading communications and marketing for 16 million customers across Northern and Central California. Before joining PG&E in 2022, he led communications for Alphabet’s X initiative focused on grid decarbonization and previously held leadership roles at Hitachi, GE, Cisco, and Text 100. He was PRWeek’s 2014 North America Public Relations Professional of the Year.

Following a 13% electric rate increase in January 2024, PG&E faced steep declines in customer satisfaction and brand trust. Rising bills, compounded by extreme weather, intensified affordability concerns and strained customer relationships. To rebuild trust, PG&E launched a three-part communications strategy: Open Lines, a CEO-led campaign acknowledging customer frustration; a yearlong effort highlighting wildfire safety investments; and communications supporting companywide cost-reduction initiatives. By summer 2025, the strategy delivered measurable results: PG&E achieved the largest year-over-year Brand Trust increase of any U.S. utility (+17%), while customer satisfaction, perceptions of rates, safety confidence, media sentiment, and overall trust all rebounded significantly.

Denise has served as Snowflake’s Chief Marketing Officer since 2016, leading global marketing and playing a pivotal role in Snowflake’s revenue growth from $1 million to over $4 billion. With over 25 years of technology marketing experience, she previously served as CMO of Apigee, acquired by Google after its IPO. Earlier, she built global marketing at Genesys, another IPO success later acquired. Denise holds a BA from Stockholm University and an MBA from Georgetown University.

My proudest accomplishment has been helping build Snowflake into a company defined not just by historic milestones but by a culture of putting customers first and enabling people to thrive. By obsessing over customer success, Snowflake grew from a challenger to a global leader in Data + AI. Yet the most meaningful part of this journey has been seeing people grow—many starting in entry-level roles and advancing to senior leadership. Creating an environment where collaboration and talent flourish has been as rewarding as business results, shaping a team and company that will carry the industry forward.

Kimberly Storin is the Chief Marketing Officer at Zoom, where she leads a global marketing organization across four regions and is responsible for repositioning Zoom as an AI-first enterprise platform. A former M&A and crisis communications strategist, she is a revenue-first marketing leader who treats brand as infrastructure and demand as a direct driver of business growth. She was named #45 on Forbes’ 2026 World’s Most Influential CMOs list.

Zoom was known for one thing: video meetings. My job was to change that and to make marketing the engine that drove the transformation. In 14 months, I unified a fragmented global organization, repositioned Zoom as an AI-first enterprise platform, and built a Brand-to-Demand system that delivers measurable results. Our brand campaigns reached hundreds of millions of people globally. Pipeline contribution, cost efficiency, and buyer consideration all moved significantly. The work we’ve done in the last year is the foundation for what Zoom becomes next.

Ginny Ziegler is Chief Marketing Officer at Pearson, where she leads a global Marketing & Communications organization spanning 35 countries. With more than 30 years of experience, she has led large-scale brand, digital, and business transformation initiatives for organizations including HP, IBM, Intuit, Xerox, Accenture, and Pearson. Ginny holds a BA from the University of Bristol and serves on the board of the San Francisco Opera Guild.

Over the past 18 months, I led the transformation of Pearson’s global Marketing & Communications organization, bringing together more than 570 marketers across 35 countries into a unified operating model. The transformation delivered millions in savings — more than three times the original target — while also generating millions in operating profit that were reinvested into growth. We launched Pearson’s first global brand campaign in five years, reaching more than 120 million people with over 90% positive sentiment, increased marketing-sourced pipeline and grew eCommerce revenue by double digits. Most importantly, we built a more connected, high-performing culture capable of leading change at scale.
