About JDOC

One team, one line.
Built in Tokyo.

JDOC is a bilingual marketing team that takes global brands from impression to conversion in Japan, whether they are entering the market or already operating here.

We plan the line, run every step of it ourselves, and get judged on what comes back.

1

Execution

We don’t just advise. We embed ourselves in your team as true execution partners, and run what we recommend.

2

Data-driven

Actionable, data-based decisions that eliminate ambiguity. Every plan starts from validated numbers, not opinion.

3

Transparency

We share what works, what doesn’t, and why. Especially important when we rarely meet in person.

4

Outcome-first

Tangible growth and measurable impact, not outputs. The number you care about is the number we report against.

“With a career rooted in Germany’s leading global enterprises (SAP, BASF, Audi) and a background as a Japanese-German simultaneous interpreter, I specialize in bridging cultures through high-impact marketing and consulting. I hold a graduate degree from Heidelberg University.

My expertise lies in engineering explosive organic growth. Even for highly niche products, I design precise strategies and creatives that generate hundreds of thousands to millions of views without a dime spent on ads. On Instagram, I successfully built a following of 150,000+ in just 6 months with zero ad spend. However, my ultimate focus is never on vanity metrics; I am relentlessly committed to driving bottom-line revenue and tangible business growth.

Having backpacked across more than 40 countries, I experienced firsthand the world’s profound fascination with Japanese culture. Driven by this realization, I co-founded JDOC with a clear mission: to deliver Japan’s unique value to the global stage.”

“Operating at the intersection of technology and marketing, I build digital ecosystems that drive tangible revenue. During my student years, I was selected as Japan’s AI & Robotics representative by the Ministry of Foreign Affairs and launched an IT service from scratch, rapidly scaling it to 20,000 monthly active users.

After exploring 30+ countries, I joined SAP Japan, where I led many large-scale IT system implementations.

My strength is cost-efficient acquisition. Because I oversee everything from data-driven ad operations and Web/App development to content marketing, I have delivered B2B leads at under ¥1,000 each and trial sign-ups for a school business at a CPA in the ¥2,000 range. I don’t just “build systems”; I build engines for direct business growth.

I know both the technology and the marketing, and I use both to accelerate our clients’ business. That is why I co-founded JDOC.”
