About Bob "Masa" Matsuoka
Bob "Masa" Matsuoka is a technology executive whose career pairs the strategic reach of a public-company CTO with the hands-on fluency of a working developer—a combination built over a coding journey that began in ninth grade and now spans five decades.
Current Role: CTO at Duetto
Masa serves as Chief Technology Officer at Duetto, the hospitality industry's leading revenue management platform, serving thousands of hotels, casinos, and resorts worldwide. He leads the technology strategy behind Duetto's Revenue & Profit Operating System, guiding the engineering organization through continued growth while advancing the AI-powered pricing, forecasting, and demand-optimization capabilities at the platform's core.
Thought Leadership in Agentic AI
In 2024, Masa emerged as a leading voice in the agentic AI coding community—not from the sidelines, but through practical implementation. He is the founder of HyperDev (hyperdev.matsuoka.com), a publication focused on the patterns, practices, and best practices of agentic AI-powered development, now reaching an audience of more than 20,000 readers. He also founded AI Power Rankings (aipowerrankings.com), a platform for evaluating and comparing AI development tools.
What distinguishes his contribution is that he builds what he writes about. His open-source work includes an AI code-review tool spanning multiple LLM providers and a multi-agent project management system, released through the npm ecosystem with meaningful community adoption. This insistence on hands-on credibility—being a practitioner first—anchors his perspective on where the field is genuinely heading versus where the hype points.
A Career Built Across Scales
Before Duetto, Masa's path moved fluidly between the entrepreneurial and the enterprise. He founded Citymaps as Chief Technology Officer, building product and team from the ground up alongside non-technical founders and ultimately steering the company to its 2016 acquisition by Tripadvisor. The transition carried him into a near-decade at Tripadvisor, where he rose from Director of Engineering to Head of Product Engineering and Interim CTO. In that role he reported directly to the CEO, oversaw a $140M engineering budget, and led an organization of more than 550 engineers supporting a $1.5B ARR public company.
Those years were defined by transformation—modernizing a two-decade-old consumer product stack into a federated, microservice-based architecture, establishing engineering offices in Romania and Croatia, and growing a global contractor program from twenty engineers to several hundred. Following Tripadvisor, he applied that experience across fractional and advisory roles—including fractional CTO engagements with Recess and EWTN—before stepping into his current leadership at Duetto.
Leadership Philosophy
Across every scale he has worked at, Masa has held to a people-first conviction: the most durable engineering solutions emerge from understanding human needs, not merely technical requirements. His guiding belief is that engineering should be the last way to solve a problem, and that the real breakthrough in agentic AI lies not in the technology itself but in discerning which human tasks merit automation and which merit augmentation.
"The real breakthrough in agentic AI isn't the technology itself—it's discovering which human tasks we should automate and which we should augment. I'm more interested in the architecture of human-AI collaboration than in the hype of full automation."
