AI-powered web app and SaaS development, AI automation of everyday operations,
and migration away from WordPress and other aging sites.
A web development studio that builds both the technology and the words in-house.
Let'sBJJ Inc. is an AI-first web development company. We plan and build web apps and SaaS, automate operations with AI, and migrate aging sites off WordPress and other legacy platforms. What sets us apart: the copywriting that moves people is made in-house too.
Web app / SaaS development, AI automation of operations and content, large-scale website migration, and website production. Because we plan and run our own SaaS and media, we build with operation and customer acquisition in mind — never "built, delivered, goodbye."
Clinics, membership businesses, e-commerce, schools — industry doesn't matter. What our clients share is the need to earn trust online and build relationships that last.
Meetings happen over LINE or Zoom, and when coaching is needed we produce tutorial videos on the spot. We meet in person only for filming or when we happen to be nearby. Everything runs online because it's efficient — and because Fujiwara likes to work from anywhere.
Queue systems, booking management, video subscriptions — we build web apps from scratch, drawing on years of planning, building, and operating our own SaaS.
Automated article and content generation, hands-free SNS posting and data collection — AI-powered automation that replaces daily manual work with systems that never stop.
End-to-end migration away from WordPress and other legacy CMSs, from architecture to implementation. Dramatically better speed, security, and running costs.
Members-only sites with a powerful video search engine and player. Full-scale platforms specialized for content businesses such as instructionals and training video.
Sites built around copy, combining video, photography, graphics, and music production. We surface every question and every doubt a customer has before joining or buying.
Relentless audience research works backwards from what prospects worry about and how they actually think. The copy is structured so readers convince themselves as they read.
Alongside client work, we plan, build, and operate our own SaaS and media. Running them ourselves is how we know the pitfalls of development — and the reality of customer acquisition.

Born in Oita, Japan. Moved to Tokyo as a teenager to make a living from music, joined a game studio, and worked on sound production for Nintendo titles — while running his own indie music label and selling CDs online. That was the start of a lasting fascination with selling and drawing traffic on the internet.
After growing his own blog to tens of thousands of monthly pageviews, he founded an internet marketing consultancy. Today his work centers on planning and building web apps and SaaS and automating operations with AI — with acquisition strategy and copywriting still handled in-house. Father of two.
