Long before May Petry was responsible for explaining a database company to developers, executives, and investors, she was learning the sharp discipline of speaking for technology companies in public. In the late 1990s and early 2000s, that meant agency work followed by software communications at Sun Microsystems. A company could make news with an acquisition, a product release, or a service interruption, and the spokesperson had to find the useful fact inside the noise. The work rewarded preparation, accuracy, timing, and a feel for what another person actually needed to know.
Three decades later, the channels are different and the feedback arrives much faster. Petry is Chief Marketing Officer at MongoDB, where she leads global marketing for a data platform used by developers and enterprises. Her remit spans the broad modern CMO map: narrative, digital experience, demand, self-service adoption, product-led growth, enterprise sales support, and the operating machinery that connects them. Yet the old communications question still sits underneath it all. What is the clearest true thing we can say, and why should the person on the other side care?
The spokesperson learns to read a dashboard
Petry's early career was built in public relations. After agency roles, she spent more than five years at Sun, then led corporate public relations at BEA Systems. At Yahoo!, she moved through global communications positions that covered products, corporate matters, and regional work. These were large organizations with famous brands and complicated constituencies. Communications was not decoration. It was a way to make strategy legible while events were moving.
At Hewlett-Packard, and later Hewlett Packard Enterprise, her center of gravity shifted toward digital marketing. The distinction matters. Communications asks whether the message travels. Digital growth asks what the person does next. A page view, a search query, a registration, a product trial, and a sales conversation can form a visible chain. The storyteller gains an instrument panel.
The transition coincided with an unusual corporate assignment. When Hewlett-Packard split into HP and Hewlett Packard Enterprise in 2015, Petry helped steer digital work through new sites, new systems, new organizational lines, and new customer paths. In a 2016 industry talk, she described the marketing technology environment as one in which teams could have abundant data and still lack insight. Her practical answer was not another dashboard. It was clearer questions and deliberate over-communication through change.
That sentence is easy to agree with and hard to operationalize. Customers do not arrive as a single audience. At an enterprise software company, the person experimenting with a tool may be a developer, the economic buyer may sit several levels away, and the eventual system may need approval from security, finance, and operations. Each participant encounters a different risk and a different promise. Starting with the customer means preserving those differences while making one coherent case.
Growth becomes an experiment, then a system
After HPE, Petry led digital marketing at FinancialForce and global demand generation and digital marketing at Pure Storage. In a 2018 essay marking a year at Pure, she wrote about finding a professional tribe. The theme fits her operating style: growth is performed by a group with complementary strengths, not by a lone marketer pulling a clever lever.
She joined MongoDB in early 2022 as Vice President of Digital and Growth Marketing. The team's stated job was precise: find the next likely customer, help that customer succeed on Atlas, and accelerate later growth. Its goals covered awareness, self-service revenue, digital experiences, and sales opportunities. This was marketing close to the product, where customer behavior could inform the next campaign, onboarding change, or audience choice.
MongoDB later credited Petry with scaling the self-serve business, establishing global revenue marketing, and tightening execution across digital, product-led, and enterprise sales motions. She moved into senior revenue marketing leadership and, in 2025, became CMO. At the company's September 2025 Investor Day, her assigned subject was self-service and product-led growth. It was a revealing slot: the marketer was explaining an operating engine, not presenting a mood board.
The engine matters because MongoDB serves two journeys at once. A developer can begin by building. An enterprise can standardize a platform across teams. The marketing organization has to respect the immediacy of the first experience and the complexity of the second. Petry's background gives her a useful double vision: the communications leader's concern for meaning and the growth operator's insistence on evidence.
The manager as arranger
Petry's most distinctive public idea about leadership is that the boss does not need to outperform every specialist. The leader's responsibility is to help people do their best work and arrange those outputs so they become more efficient and more consequential together. It is a producer's view of management. The achievement is not the solo. It is the composition.
One of her favorite questions for a job candidate is, “What is your superpower?” The phrase is playful, but the information is practical. A team becomes easier to design when its members can name the unusual thing they contribute. One person sees patterns in a messy funnel. Another turns technical detail into a memorable sentence. Another can host the candid meeting that unsticks a decision. The question only becomes useful when the organization builds around the answer.
Her development advice is correspondingly concrete. Be authentic and vulnerable. Give people individual growth plans. Make the standard for improvement visible. Create regular space for feedback and recognition. Encourage employees to seek mentors, coaches, and allies while remaining responsible for their own development. These are not slogans about culture. They are recurring management tasks.
Petry has described the experience of being the only woman and person of color in a room, particularly early in her leadership career. She remembers being told to use her voice when, from her perspective, she was already speaking. The lesson she carried forward was subtler: speaking and being heard are different skills. Influence requires attention to how other people receive a message, not merely the courage to deliver it.
She treats imposter syndrome with similar practicality. Rather than promising that it disappears with seniority, she has suggested putting it to work as fuel for curiosity, empathy, collaboration, and the growth of other people. Discomfort becomes a prompt to ask a better question. The same habit that helps a marketer investigate a weak signal can help a leader resist false certainty.
Her own learning path has moved between formal study and peer communities. Petry earned a bachelor's degree in English at Loyola University Chicago, then built her technical fluency inside software companies rather than through an engineering credential. She is a Senior Fellow of the American Leadership Forum in Silicon Valley and has participated in marketing leadership groups including the CMO Council and The Peer 150. The combination is telling. Language gave her an entry point; long exposure to products and customers supplied operating context; peers offered a place to pressure-test the decisions that become harder to discuss as a title grows. Her career makes a quiet case for range: a marketer can respect technical detail without pretending to be the engineer, and can lead specialists without competing with their specialty.
The next audience may be an agent
The market around Petry has shifted again. Artificial intelligence is changing how software is discovered and assembled, while database companies argue for their place beneath production applications. Petry has written that marketing to builders increasingly includes earning trust with the agents and systems that influence what gets found, recommended, and created. It is a fresh distribution problem with an old requirement: the underlying claim still has to be clear enough to travel.
Her public commentary remains tied to foundations. She has emphasized clean data, clear accountability, scalable guardrails, observability, and security as organizations move from AI experiments toward production systems. The position suits a career shaped by translation. Marketing has to turn technical architecture into customer consequence without sanding away the truth.
There is also a personal loop in the work. In the summer of 2026, Petry visited MongoDB's Asia-Pacific and Japan team in Singapore, the city where she was born. She described a candid discussion with regional marketers about what was working, what was not, and what the group should stop or prioritize. She also held an open question session with the broader office. The visit combined the habits that recur across her career: listen, choose, speak plainly, then make room for renewal.
Petry's path does not offer a single campaign to copy. It offers a more durable piece of operating logic. Communications taught her to find the sentence. Digital marketing added the journey. Growth work added the experiment. Executive leadership added the obligation to help other people see and use their own strengths. The signal was never hiding in one dashboard. It lived in the relationship between the customer, the evidence, and the team willing to act on both.
