DeeDee Walsh

Dee Dee Walsh is a software and technology industry veteran with over 25 years of experience building developer ecosystems, launching products, and driving go-to-market strategy for enterprise software companies. She currently leads business development and developer marketing at Growth Acceleration Partners (GAP) and its product brand GAPVelocity AI, where she is focused on helping enterprises navigate the transition from legacy systems to modern, cloud-native architectures. Before joining GAP, Dee Dee served as Vice President of Marketing and Business Development at Mobilize.Net, a code modernization company she helped guide through its acquisition, with the company’s core migration technology ultimately being acquired by Snowflake and its Application Migration Unit becoming part of Growth Acceleration Partners. Her earlier career at Microsoft spanned foundational roles in the developer tools ecosystem, including contributions to multiple versions of Visual Studio, the launch of the Microsoft Store, and the creation of the Visual Studio Partner Program and Windows Logo Program. Dee Dee’s current work centers on the intersection of AI and application modernization. She writes extensively about legacy-to-modern migration strategies, particularly VB6-to-.NET, Microsoft Access-to-Blazor, and PowerBuilder modernization, as well as the practical application of agentic AI in enterprise development workflows. Her perspective is grounded in decades of hands-on experience seeing what works (and what doesn’t) when organizations attempt to modernize at scale. She holds a certification in AI Applications for Growth from Kellogg Executive Education and holds two patents related to multi-merchant purchasing and payment security systems. Outside of her professional work, Dee Dee serves as a Board Member of the Microsoft Alumni Network, a Board Advisor for Women in Cloud, and previously chaired the board of FIRST Washington, supporting youth robotics education. She is a graduate of Brigham Young University.
