Chikuma Tsuboi

Welcome. I'm Chikuma Tsuboi.
I help businesses build AI systems they can own and operate—not just use.

I'm the founder of dera.ai. We work at the intersection of culture and technology here in Tokyo, helping SMB leaders, founders, and change-makers amplify what makes them unique. We don't just consult—we build alongside you.

Here's what we believe: there's a future where lots of small teams with smart systems win. Not just using AI tools, but building infrastructure you control—something that benefits every business.

What this looks like in practice:
I run dera news, a 5min read AI intelligence newsletter reporting trending patterns in AI world delivered to your inbox every Monday morning. It's got multiple AI layers built in them. That's the kind of system I build for clients.

I'm developing Ramen Road, a geo-location game that turns learning ramen culture into collectible experiences. It's a beta project, but it shows what's possible when you think about branded social games for your own business or community.

I've built and failed at a dozen other things along the way—those taught me the most.

If you're building something and want a partner who understands both the strategy and the execution please email me. I'd love to hear what you're creating.

Until then, take care.
