Our Principals

Zenda®​ Leadership

Each of our principals has more than 30 years’ experience in operational design for complex
enterprises — a space few designers venture into. Our roots extend to the largest global
industrial software development efforts, and we cut our teeth in an internationally respected technology-design firm, working with leading global brands such as IBM, Ford, Exelon, Goldman Sachs, Pfizer, Bloomberg, NHS, and many others.


Johanna Hambrose CEO

Prior to founding Zenda in 2016, Johanna co-founded the internationally recognized design firm Electronic Ink, leading an industry for 25 years by defining the human experience with technology-driven products. Johanna brings 30 years of business law experience, as both practitioner and business executive, to Zenda. It is her personal commitment to excellence that distinguishes Zenda in its promise to exceed client expectations.

Establishing Zenda as a certified woman-owned business, Johanna has created a safe environment which supports the free exchange of ideas, challenges norms, and encourages exploration. Bringing diverse perspectives and experiences to our work continues to attract top designers who see beyond the computer screen. Johanna is again transforming an industry, through Work DesignTM.


Mary Caracappa COO

Mary joins Zenda®​ following a 30-year, cross-disciplinary career as a Managing Director at Morgan Stanley and as a former client and believer in applying HCD to solve complex business problems.

An accomplished executive with a powerful blend of strategic agility, execution-focused leadership and financial acumen, Mary steered global transformation initiatives to create efficiencies, mitigate risk and scale businesses during significant growth periods and amid a changing regulatory environment in global leadership roles as Head of New Products; CAO/CIO for Merchant Banking; Sarbanes-Oxley Compliance Officer; Operational Risk Head for Finance; and Head of Internal Audit for corporate functions. ​

A recognized change agent with a strong bias towards action and ability to tackle business complexities, Mary successfully led distributed work teams across disciplines and business lines to remediate operational deficiencies, build new infrastructure and capabilities, enhance internal controls and evolve the financial reporting landscape.


Chief Design Officer

Harold was among the first professionals forging a path for design in the technology industry. He co-founded Electronic Ink, the first design firm dedicated exclusively to the human-centered design of software, and attracted landmark projects including operating systems, early banking machines, medical record systems and financial services platforms.

Over thirty years of designing enterprise systems, Harold extended the voice and impact of design beyond software user interfaces. Recognizing a need for improved collaboration among the diverse disciplines inside business enterprises led to the development of operations modeling: human-centered design research informing the creation of models articulating the relationships, risks and opportunities among the enterprise’s human context, business processes, technology and data.

Harold is the author of Wrench in the System published by John Wiley & Sons. He has taught courses at various universities and has lectured at conferences around the world. Harold served as an expert in design and technology for international legal proceedings. He received the Alumni Achievement Award from Carnegie Mellon University for significant contributions to the design and technology industries and is a member of the Advisory Board of CMU’s College of Fine Arts.
