Modern customers expect more—smarter experiences, faster responses, and interactions that feel personal and relevant. But for many organizations, meeting these expectations feels out of reach. Legacy systems, disconnected data, and rigid processes make it hard to keep up, let alone lead. Growth stalls, campaigns underperform, and the promise of digital transformation remains unfulfilled. That’s where Iconic Business Leaders make all the difference. They don’t just understand technology—they know how to turn complexity into clarity. By reimagining customer journeys, embedding AI into strategy, and fostering agile, cross-functional teams, they help businesses move faster, serve smarter, and build the kind of trust and value that drives lasting success.
One such leader is David C. Edelman, who has been inspiring leaders across the marketing landscape for over 30 years — now as a sought-after Executive Advisor, Bestselling Author, Fellow at Harvard Business School, and Senior Advisor with BCG. Throughout his career, David has helped executive leaders unlock growth by using digital tools, customer data, and now, AI, more effectively. He has held key roles at BCG, Digitas, McKinsey, and Aetna—where he helped raise marketing’s business impact and reshaped customer experiences.
As CMO at Aetna, his launch of personalized onboarding videos led to a 20% drop in service center calls and a 75% reduction in unnecessary ER visits, and he doubled the impact of marketing on the company’s growth within his first 18 months. In another example, he helped a major pharmaceutical company boost physician engagement threefold by implementing agile marketing practices. His strategic guidance to OfferFit, a startup later acquired for over $300 million, shows his ability to drive impact with early-stage companies as well.
Back in 2010, David introduced the widely adopted concept of the “customer decision journey” in a cover story for the Harvard Business Review, which became a foundation of modern marketing strategy. His recent co-authored book, Personalized: Customer Strategy in the Age of AI (Harvard Business Review Press, October, 2024) became a global bestseller. Whether through advising, writing, or teaching, he continues to guide organizations toward smarter, faster, and more connected ways to grow.
Early Beginnings at BCG
After graduating from Harvard College and Harvard Business School, David C. Edelman began his career in 1986 at Boston Consulting Group, where he helped clients explore the early potential of customer data — long before the digital age took off. This pioneering work laid the foundation for his widely recognized article in 1989, Segment-of-One Marketing, which catapulted his consulting and speaking career. Building on this momentum, he later co-developed BCG’s e-commerce practice and, in 1999, joined Digitas to deliver data-driven digital experiences through analytics and CRM. Following Digitas’ acquisition by Publicis, David moved to McKinsey & Company, where he built and led the global Digital Marketing practice. There, he helped clients embrace the cultural transformation, agile methods, marketing technology foundations, and new organizational roles such as Chief Digital Officer which were required to win.
His transition from consulting to corporate leadership came in 2016 as Aetna’s first Chief Marketing Officer, where he repositioned the brand as a trusted health partner, upgraded its digital tools, built its customer experience management program, and was actively involved in the company’s merger with CVS. After Aetna, David brought his expertise into academia, teaching marketing at Harvard Business School for three years. Today, he continues to shape the future of marketing as a sought-after independent advisor, working with enterprise executive leadership teams on how to drive AI-powered, customer-centric growth, coaching smaller AI start-ups on customer success strategies, and serving as a Senior Advisor with BCG, where he helps the firm’s clients unlock new opportunities.
David C. Edelman’s influence extends far beyond the boardroom. Through a constant stream of articles, webinars, public speeches, and appearances on dozens of podcasts, his thought leadership and deep industry engagement continues to shape how businesses grow and connect with customers.

Learner, Teacher, Advisor, Influencer
In 2024, David C. Edelman stepped away from full-time teaching at Harvard Business School to support the launch of his book with more client workshops and speaking engagements. Nonetheless, he remains involved with Harvard Business School, providing advice on integrating AI into the marketing curriculum and contributing occasional guest lectures.
His time in the classroom deepened his appreciation for the foundational principles of marketing—segmentation, positioning, and value proposition design. In today’s fast-moving world of AI and hyper-personalization, David believes these core concepts are more vital than ever. However, he observes that many companies leap into advanced technologies without a solid strategic base. Through his advisory work, he continues to guide organizations in anchoring their digital transformation efforts in these essential marketing fundamentals, and making sure the C-suite is aligned to make them happen.
Emphasizing Change Beyond AI
David C. Edelman emphasizes that business education in the AI era must go beyond technical training. It’s not just about learning how to use AI tools—it’s about understanding how AI is fundamentally transforming how teams work. For example, tasks that once required separate specialists, like analytics, content creation, or customer targeting, are increasingly getting integrated through automation, changing the structure and function of modern marketing teams.
At Harvard Business School, David has written four case studies that explore how leading companies are evolving their operations to take advantage of AI, and on how AI-driven start-ups are learning to go beyond their products to support their clients’ success. These studies emphasize the importance of aligning customer engagement strategies and internal processes with new technologies, helping future leaders think more holistically about innovation.
Power of Combined AI Capabilities
David is passionate about how the more successful AI applications have combined multiple agent capabilities to solve real-world problems in meaningful, measurable ways — GenAI, machine learning, reinforcement learning, etc. He often cites Brandlight, a startup that uses multiple AI engines to help brands track how they appear in foundational AI models like ChatGPT and Gemini, and then uncover which sources drove that placement, enabling smarter content strategies. Or SearchUnify, which brings everything a service rep needs to their fingertips, while alerting the broader organization about emerging issues, and shaping input into product roadmaps, while constantly adding to its knowledge base as customer issues arise. In his view, this kind of integrated, practical use of AI represents the future.
His understanding of innovation comes from direct, ongoing engagement with the tech world. David stays current by working with startups, attending conferences, and maintaining strong ties with CMOs. Through his role on the Advisory Board of Glasswing Ventures, a VC player focused on AI, along with many product demos that come his way and the real-world collaborations in his advisory work, he stays close to the action—learning what’s effective, what’s not, and where the next breakthroughs may come.
Automation Becomes Core to Business Strategy
David says AI-driven automation is no longer just in pilot mode — it has become a key part of how businesses run today. Companies now use it in important moments such as onboarding, where it helps coordinate multiple tasks, personalizes the experience, and speeds things up.
But even with all these benefits, David C. Edelman reminds us that the basics still matter. Companies must build trust, use customer data carefully, and avoid making things too complicated for users.
He believes the real success comes from cracking the code of balancing automation with humanity. In a world at risk of making everything AI-driven and robotic, emotion still needs to come through the interactions customers have with your brand. Yes, for simple tasks like answering common questions through a chat or phone interface, automation works well. But in more serious or emotional situations—like in healthcare or finance—talking to a real person is still critical. More importantly, humans should be designing how all of these experiences will play out from the customer’s point of view.
David also points out that automation works behind the scenes too. Tools that sense trends in social media, flag problems escalating in one’s operating data, or that simply support front-line workers with integrated access to information stored across disparate systems help teams work faster and respond better.
The main challenge, he says, is finding the right balance — knowing how to bring humanity into automation, while using automation to support human interactions.
Agility Over Rigidity
Many companies mistakenly believe that AI and digital tools can just be plugged into existing systems and start generating ROI. In truth, successful integration requires rethinking workflows and adopting a more agile, test-and-learn approach.
David C. Edelman helps organizations shift from rigid vertical structures to agile, cross-functional collaboration—an approach that has driven impressive results across industries:
- Pharmaceutical Company: Led a transformation to compliant agile marketing, tripling physician engagement with clinical data about the drug’s effectiveness and best uses.
- Consumer services brand: Injected personalization and rapid cycle testing into their operations, raising the Net Present Value from key marketing programs by 400%.
- Aetna (as CMO): Personalized onboarding videos cut service calls by 20%; urgent care education reduced unnecessary ER visits by 75%.
- OfferFit (Start-up Advisory): Advised on go-to-market; its successful AI-driven multi-variate testing services fueled its $300M+ acquisition by Braze.
This success came not just from technology, but from a mindset focused on experimentation and real customer needs. In his advisory work, David C. Edelman continues to apply this approach — starting small, testing continuously, and scaling what works.
Innovation Recognized by Meta
David C. Edelman serves as an independent board member at StrataTech, a vocational education company specializing in infrastructure trades such as welding, plumbing, and HVAC. One of their key innovations has been the development of “Occuweld,” a virtual reality-based welding simulator created using Meta’s VR technology. This tool offers realistic tactile feedback and enhances classroom learning, now used both in Stratatech’s own curriculum and by community colleges who license it. Occuweld was also recognized with a top education innovation award from Meta.
On the marketing front, StrataTech manages the entire student acquisition journey—from initial inquiry to enrollment using sophisticated analytics, ZIP code-level targeting, and a growing range of AI tools to repeatedly improve efficiencies every year. The company also designs tailored training programs for businesses aiming to upskill staff, using a variety of advanced educational tools.
Unified Teams, Unified Success
One key insight David C. Edelman shares is that leadership and innovation are not solo efforts—they require collaboration across the entire organization. Success doesn’t come from a single department but from teams working together. To make leaps in performance for marketing and customer experience, it’s essential for teams such as compliance, service, sales, data, and operations to be aligned and work in sync, with air cover from top executives. That’s why his advisory work includes multiple members of the C-Suite, and he’s often brought in by the CEO.
A clear example of this was his leadership of the onboarding revamp at Aetna. Daily collaboration among different departments made it possible to test and roll out new solutions quickly. With the growing role of AI, this kind of teamwork has become even more important, as AI connects data from various parts of the business. To truly improve customer experience and operations, companies must move beyond siloed ways of working and create a culture where cross-functional teams solve problems together.
Trust Begins with Transparency and Personalization
David believes that building customer trust starts with delivering genuine value — through clear, relevant communication, rather than overwhelming people with irrelevant content and offers.
A strong example of this comes from his work at Aetna:
- Redesigned Onboarding: The team revamped the new-member experience to be more personalized and informative. They cut out all extraneous emails that were not truly relevant for a new member.
- Personalized Videos: Collaborated with SundaySky to create videos that explained each person’s plan, their assigned doctors, and key benefits.
- Greater Clarity: These videos helped members understand their coverage better, reducing confusion.
- Improved Satisfaction: Customers felt more confident, leading to higher satisfaction and fewer service center calls.
- Smart Use of Data: This approach showed how thoughtful, respectful use of data can deepen relationships and become a strategic advantage.
David’s view is that when data is used with care and purpose, it improves the customer experience and builds long-term trust. As cited in his book, the key to differentiation as personalization becomes a basis of competition will be how you “empower, know, reach, show, and delight” your customers to fuel a constant loop of value improvement.
Looking ahead, as noted in the final chapter of his book, he sees leaders going even further to provide integrated solutions to their customer. Building ecosystems on AI platforms that share data across multiple partners to answer a consumer’s need to plan a trip, redesign a kitchen, deal with a car accident, and coordinate chronic disease care. AI agents can integrate and manage the movement of data, leading to whole new forms of customer value delivery, not just internal efficiencies.
Guiding Principles for Future-Ready Leadership
When David C. Edelman starts working with clients, he often sees them focusing too much on short-term returns, prioritizing performance marketing at the expense of brand-building. This imbalance can hurt long-term growth. He suggests that dedicating about 30% of the marketing budget to brand development leads to sustained results over time.
Few clients also have crisp maps of how data flows throughout their organizations. They lack the instinctive understanding of the information assets they could build or are losing the opportunities to create because of their architectures.
Lastly, another common issue is over-specialized marketing teams, which slow down execution. Instead, David advocates for smaller, cross-functional teams or “pods” of 5–6 people that can run integrated campaigns more efficiently—requiring a rethink of team structure and training.
Putting this all together, David C. Edelman believes strong leadership today requires ruthlessly focusing on customers, being curious about technology, managing your data as a critical asset, and acting with speed and intention. AI is bringing data together, democratizing capabilities across teams, and opening up new possibilities for innovation. Winners, as proven in his research on personalization, are shifting from vertical to more horizontal, collaborating modes of operating. And in the process, they are redefining how one competes — leveraging efficiencies, but even more so, delivering continuously improving, differentiated, brand value.
