STRATEGY Business models & roadmapPRODUCT App × Device × AIDECISIONS Data & business growth
I’m a Product Manager working across product strategy, business, AI, and connected products,
with particular strength in taking products from 0→1 and scaling them from
1→N. My background in industrial design and UX/UI helps me connect business goals,
user needs, and execution.
My product experience includes end-to-end ownership of a mobile app within an AIoT product ecosystem,
from shaping product strategy, business models, and roadmaps to defining features and product logic,
planning device–app interactions and AI-enabled capabilities, identifying new monetization and revenue
opportunities, and driving cross-functional delivery.
I also define product tracking plans and key metrics, then use what I learn from the data to improve
features, support product decisions, and identify new business opportunities.
ENTREPRENEURSHIP / IN THE REAL WORLD
2014 · GUESTWHAT Social dining · 50+ events2022 · PLANTTHEORY Kampo tea · Until July 2026
I’m someone who enjoys turning curiosity into action. When something interests me, I rarely stop at ideas.
I look for ways to build, test, and experience it in the real world, whether through my work or my own ventures.
My first startup experience came in 2014, when I co-founded 『GuestWhat』, a social dining marketplace connecting local hosts with guests for hosted dining experiences.
I worked across operations, business development, service design, and product design, helping turn the initial idea into an MVP and iterating it through real user feedback.
In one year, we hosted 50+ events and reached 400+ participants.
Years later, that same mindset led me to found『 Planttheory 』, a Kampo tea brand 🌱, in 2022.
I built and operated the business until July 2026.
Building the business gave me firsthand experience of what it takes to turn an idea into a real product and business, while making decisions with limited resources and real customers.

integration, and carrying that work through execution and product launch.

I believe strongly in continuous learning. I reflect on what I don’t yet know, build structured ways
to learn it, and gradually turn unfamiliar problems into areas I can understand, navigate, and act on.

I’m always curious about messy product problems.
