Heather MacLeod’s career begins with a useful contradiction. She studied accounting and marketing at the University of Illinois, then went to work in advertising. One discipline asks whether the columns reconcile. The other asks whether anybody will look up. Put them together and you get a fair sketch of the work she has pursued ever since: turn attention into something accountable, and make a complicated business intelligible without sanding away the truth.
Her first professional stop was media planning at Young & Rubicam. By 1995, she had moved into account management at Leo Burnett, where she spent nearly seven years. The agency years gave her a close view of how a promise travels. A client has an ambition. Strategists sharpen it. Creative teams give it a shape. Media carries it into the world. The account lead stands in the middle, translating pressures in both directions and keeping the whole thing from becoming a handsome answer to the wrong question.
That skill would prove portable. MacLeod left the agency world for Accenture in 2003 and stayed for more than eleven years. Her remit grew into North America marketing, including leadership work for the Products operating group, a business serving automotive, consumer goods, hospitality and retail clients. The subject had changed from campaigns to capabilities. The audience was now weighing transformations that could touch supply chains, customer systems and thousands of employees. The basic assignment remained familiar: understand what the business can do, what the client needs to do, and where the two stories honestly meet.
MacLeod also kept a formal classroom running alongside the apprenticeship. While at Leo Burnett, she completed an MBA in strategy and technology management at Northwestern University’s Kellogg School of Management, graduating in 2002. The pairing gave her two simultaneous views of a business problem: the account team’s close-range responsibility for the work and the strategist’s wider view of markets, systems and tradeoffs. In 2018, after senior roles at Accenture and JLL, she completed Harvard Business School’s Advanced Management Program. Her education therefore appears at two different turns in the career, first as she moved from agency work toward consulting and later as her responsibilities became more global. She now extends that connection through board service with the HBS AMP 195 Foundation, an alumni-led nonprofit focused on continued education, leadership and scholarships. The through line is less about collecting institutions than returning to structured learning when the size of the questions changes.
A career built in chapters
The brief gets bigger
In 2014, JLL recruited MacLeod to lead marketing for its Americas Corporate Solutions business from Chicago. The appointment was a bridge between two kinds of complexity. Professional services firms sell expertise that is difficult to package. Corporate real estate adds physical space, workplace behavior and operating cost to the mix. The marketer has to explain a service while also giving form to a future that has not been built yet.
MacLeod kept moving toward businesses where the offering is broad and the buying decision is consequential. At Publicis Sapient, she became global head of marketing for industries and alliances. At Cognizant, she served as chief marketing officer for Digital Business & Technology, a multibillion-dollar organization spanning artificial intelligence, analytics, digital engineering, connected products, applications, infrastructure and cloud. She was also part of that unit’s executive leadership team.
The list of services in that Cognizant portfolio reads like a vocabulary test for modern business. It also reveals the hidden problem of enterprise marketing. Each capability has its own specialists, economics and proof. The buyer rarely wants a glossary. The buyer wants to know which pieces belong together, what will change, and whether the people proposing the change can be trusted to carry it through.
“Innovation relies on creativity, collaboration, and shared vision.”Heather MacLeod
MacLeod’s public language tends to join terms that corporations often separate. Speed sits next to curiosity. Innovation sits next to purpose. Technology sits next to responsibility. That pairing is revealing. A message can move quickly and still miss the room. A campaign can sound inventive and leave the client wondering what happens Monday morning. Purpose supplies a filter; curiosity keeps the filter from hardening into doctrine.
Marketing from inside the operating room
MacLeod joined Capgemini in December 2022 as executive vice president and chief marketing officer for the Americas. She leads regional strategy, planning and operations and sits on the Americas Executive Committee. The seat matters. It places marketing close to choices about markets, client priorities, partnerships and investment, rather than treating it as the department that decorates those decisions after they have been made.
Her first public reflection from the company was disarmingly human. After an early 2023 gathering in Playa del Carmen, she wrote that meeting her new teammates and listening to leaders had been more energizing than she imagined. It was the observation of a newcomer paying attention before announcing a program. Later that year, when Capgemini colleague Aruna Jayanthi received recognition as a leader in consulting, MacLeod recalled researching Jayanthi before her own interview and being struck by her record as a leader and trailblazer. The anecdote is small, but it shows the habit: do the homework, notice the person, say why the work matters.
The MacLeod signal map
That way of seeing turns up in her approach to brand partnerships. At Pocono Raceway in 2026, Capgemini’s name appeared on the No. 21 Ford Mustang fielded by Wood Brothers Racing with Team Penske. MacLeod’s recap did not linger on logo exposure. She focused on the experience built around the race for clients and on the trust, precision and shared outcomes represented by the partnership. The car was visible. The relationship was the product.
The distinction is practical for a consulting company. Capgemini cannot place its full catalog on the side of a race car, and few people would read it if it could. A partnership creates a compact demonstration: teams coordinating under pressure, specialist knowledge becoming split-second action, and performance depending on every handoff. The metaphor works because the operating reality supports it.
The reusable idea: start a complex story with the shared behavior, not the service catalog. Trust, coordination and precision make the technical details easier to place.
A human standard for technical change
Artificial intelligence has made the translation job harder. Every consulting firm can speak about models, agents and transformation. Clients still have to decide where a system belongs, how it will be governed and what result justifies the disruption. At a Capgemini SPARK gathering, MacLeod distilled the posture she wanted into three moves: act quickly, stay curious and build with purpose. The sequence avoids both paralysis and empty acceleration.
She applies a similar frame to sustainability. In an Earth Day message, she linked long-term value to measurable action on carbon reduction, responsible resource use and the design of client solutions. Her point was operational: sustainability advances when it enters everyday decisions. It is the same logic she brings to brand. A promise becomes credible through repetition at the level of choices.
MacLeod’s stated ambition extends beyond campaigns. She has written about helping current and emerging female leaders in technology bring more empathy, equality and ethical responsibility to the conversations shaping the field. Since 2019, she has served on the board of the HBS AMP 195 Foundation, a nonprofit formed by alumni of Harvard Business School’s Advanced Management Program to support continued learning, leadership and educational opportunity. She has also listed involvement with Dress for Success.
Public recommendations from former colleagues describe a leader who pairs candor with compassion, analysis with creativity and advocacy with close attention to people. Those pairings echo her career. Accounting and advertising. Agency instinct and consulting discipline. Global scale and a colleague remembered by name. None of these combinations removes tension. They offer a method for working through it.

Recognition, then back to work
The industry has noticed the body of work. MacLeod was included in the 2025 Global B2B CMO 100. In May 2026, she received the inaugural ChicagoCMO Super Global ORBIE, a category for marketing leaders at multinational organizations with more than $9 billion in annual revenue. The award fits the scale of her current remit, but scale alone does not explain the career behind it.
A more revealing measure is continuity. Across seven employers, three decades and several waves of business vocabulary, MacLeod has remained close to the same difficult exchange. Experts know what their organization can do. Clients know where their own friction lives. Marketing must build enough shared language for those two forms of knowledge to meet.
The work has become more consequential as technology has moved deeper into ordinary decisions. A media plan once decided where a message would appear. An AI transformation can alter how a company serves customers, equips employees and allocates judgment. The CMO’s words now help set expectations for systems still taking shape. Clarity is therefore more than style. It is a form of governance: name the outcome, identify the human stakes and leave less room for abstraction to outrun accountability.
MacLeod’s career offers a compact lesson for anyone selling sophisticated work. Learn the machinery. Respect the audience. Notice the collaborators. Keep the promise close enough to the operation that people can test it. The language may begin in marketing, but it earns its value when the rest of the business can live inside it.
