CPO / Product Leader / AI Product Builder
Building AI-powered products, teams, and systems that turn strategy into execution.
I am a CPO-level product leader with 7+ years of experience building and scaling consumer and B2B SaaS products. I work across product strategy, operating models, growth, and AI-driven execution — helping teams move from ambiguity to measurable business outcomes.
Selected Impact
Scaled cinema SaaS to multi-hundred million yen in recurring revenue with more than 50% profit rate.
Expanded B2B SaaS adoption while maintaining perfect retention.
Improved funnel performance through UX, lifecycle, and product optimization.
Drove strong user growth through monetization, retention, and product experience improvements.
Reduced lead time through AI-driven workflows, agent automation, and structured review systems.
What I Do
My background spans consumer platforms, B2B SaaS, and digital transformation in Japan, with a strong track record of turning strategy into operating models, roadmaps, and measurable growth.
More recently, I have focused on AI-driven product development — using AI agents, automation, and structured workflows to accelerate how teams discover, build, and ship.
Experience
Leading an 18-person cross-functional team including external partners, with responsibility for roadmap, growth, operating model, and AI-enabled transformation.
Drove discovery, roadmap prioritization, monetization, retention, and platform efficiency in a scaling environment.
Worked across platform initiatives serving 20M+ registered users and 150+ titles.
Forward Learning Program at McKinsey & Company and Bachelor's Degree in Global Japanese Studies from Meiji University.
AI-Driven Product Development
AI agents support PRD drafting, acceptance criteria, review checklists, test generation, and execution support.
Product, strategy, and execution are connected through explicit systems rather than informal handoffs.
AI-enabled processes shorten the path from insight to specification to implementation.
The goal is not isolated AI experiments, but consistent team-wide productivity gains.
Flagship Project
A fully operational multi-agent AI team built on OpenClaw and designed as a coordinated working system rather than a collection of isolated chatbots.
Handles intake, clarification, triage, scheduling, and daily coordination.
Owns requirements, PRDs, task breakdown, assignment flow, review coordination, and workflow monitoring across the team.
Supports research, analysis, market intelligence, and higher-order strategic thinking.
Owns implementation, coding, integrations, architecture, and technical delivery.
Owns strict QA, verification, bug validation, and release readiness before work moves into final review.
How the system works
Free OpenClaw Knowhow
I am distributing my OpenClaw knowhow for free: setup habits, memory design, safety boundaries, heartbeat and cron usage, and how to grow from a single assistant into an agentic engineering team.
Happy to connect and discuss OpenClaw, AI agents, and agentic engineering.
Reading Shelf
Books that shaped how I think about product, leadership, strategy, and life. Each one left a mark — these are the ones I keep coming back to.
Curated Places
A ramen map built from bowls I would actually recommend, not filler picks. Each spot here earned its place through craft, character, and the kind of flavour memory that sticks.
