I'm Sonjoy Ganguly — a C-suite executive with 30+ years transforming product, marketing, and revenue organizations across ad tech, martech, SaaS, and financial services. I don't just ship products; I build the strategies, teams, and operating systems that create durable business value. I've led M&A strategy resulting in a dozen stratgic acquisitions and exits.
I've spent my career at the intersection of product strategy, technology, revenue growth, and operational excellence. From DoubleClick in the early days of digital advertising to CPO roles at MikMak and DigitalZone, I've led organizations through the hardest inflection points — scaling teams from startup to growth stage, turning around stalled product lines, and building go-to-market engines that actually work.
My path has taken me through Media Ocean, GroupM/WPP, Deloitte, Deutsche Bank, and Madison Logic — spanning ad tech, martech, financial services, and enterprise SaaS. At each stop, the mandate was the same: take something complex, make it simple, make it scale, and make it profitable. I've held P&L ownership, managed engineering and IT organizations, led marketing, partnerships, and M&A functions, serving as the connective tissue between the C-suite vision and the execution on the ground.
I studied at NYU Stern School of Business, and I'm a frequent speaker and published contributor on topics including product-led growth, account-based marketing, B2B innovation, and executive leadership.
Most executives specialize. I integrate. My career has been defined by bridging the gaps between product, marketing, revenue, and technology — building organizations where every function operates as a single growth engine.
End-to-end product leadership: vision, roadmapping, discovery, delivery, and lifecycle management. Building product organizations from scratch and transforming existing ones for scale.
P&L ownership with a track record of driving revenue growth through pricing strategy, market positioning, sales enablement, and data-driven GTM execution.
Demand generation, ABM, content strategy, brand positioning, and strategic partnerships. Deep expertise connecting marketing investment to measurable pipeline outcomes.
Leading engineering teams, managing technical debt, driving platform modernization, and aligning technology investment with business priorities.
Building operational frameworks, process optimization, organizational design, and cross-functional alignment that enable companies to scale efficiently.
Identifying market inflection points, leading digital transformation, and cultivating a culture of innovation across the organization. Turning complexity into competitive advantage.

"Great products aren't built by product teams alone. They're built when every function — marketing, engineering, sales, operations — operates with shared intent and shared accountability."— Sonjoy Ganguly
I host conversations with product executives, founders, and operators about the real work of building products and leading teams — the strategic frameworks, the hard decisions, and the lessons that don't fit neatly into a LinkedIn post.
I also appear as a guest on industry podcasts and speak at conferences on topics including product-led growth, B2B marketing innovation, and executive leadership.
