Mary E. McCarthy

Product and Propositions Marketing Expert | Champion of the Customer | Go-to-Market Strategist

New York, New York

Results-driven, highly inquisitive senior product marketing professional with 15+ years of experience in bringing technology to life for various industries. Deep expertise in developing and communicating products and propositions for the B2B market.

I help companies successfully bring their tech products and propositions to market with a sharp focus on the needs of the B2B / B2B2C customer. I have worked on all segments: from small office/home office to medium & corporate-sized to multinational corporations, taking into account the specific pain points of each segment.

I develop and execute end-to-end marketing plans, including market sizing, customer research, content strategy, digital campaign management, sales, commercial and product engagement, launch analysis and reporting, and the management of products and propositions.

My passion is working with cross-functional teams, navigating, motivating and managing teams to meet specific objectives, deliverables and deadlines. I do this by leveraging the collective brainpower of a team, leading with a structured, yet flexible, approach and communicating effectively throughout the project.

I am both creative and analytical, with the ability to see the bigger picture and develop a vision, yet at the same time executing a vision to the finest details. Throughout my career, I have focused on problem-solving and getting into the head of the user or customer.

People know me as dedicated, disciplined, and approachable. I know how to connect and develop relationships with colleagues, customers and vendors. In every position I have held, I am the person you can rely on. Beyond that, I value my sense of humor and have learned that humor is the great connector in the work world.
