Live projects

  • Work & Camp — 嬬恋牧場Work&Camp

    The campground as a business: our 1,444m telework camp you can actually book — fiber office, pet-friendly sites and car camping from ¥7,500/night, with online booking, multi-channel payments, an AI concierge, and live cameras, all built in-house.

  • Ranch Plan — 牧場計画

    The plan to bring a closed-up roadside resthouse at 1,444m back to life — the whole thing, phase by phase, as a mountain telework camp.

  • Tsumagoi Ranch — 嬬恋牧場

    Our mountain telework camp at 1,444m in Tsumagoi, and the live screen that watches over it — room temperatures, cameras, and who's on site, from anywhere.

  • Tracker — 勤怠管理

    Daily reports and shifts for dev teams who keep forgetting which day they worked.

  • Solo Boss — 一人社長

    For one-person companies who'd rather not spend Sunday on accounting.

  • Wedding Kiosk — 結婚式受付端末

    A kiosk for a wedding party — guests sign the book, share photos, and find their seat.

  • Skin Analysis — 肌診断

    Take a selfie, see what your skin's been up to lately.

  • ProjectFlow — プロジェクト管理

    One screen for the project, the invoice, and the part where your team forgets what's next.

  • glot.it — タイ語学習

    A Thai-learning app for the kind of learner who's tried three other apps and bounced. (App Store · Google Play)

  • Help Her Take Photo — 写真撮って

    For when 'let me see it… is that all?' needs to stop happening. (App Store · Google Play)

  • yen-yen — 家計簿

    A household kakeibo for two — where the money actually went, and what's due next. (App Store · Google Play)

  • Babuu AI — 動画生成AI

    An early version of a video-generation site we built with our friends at Babuu AI.

  • The Wanting Mind — 欲望する心

    A small book about wanting things — readable on the web, listenable as a podcast. (App Store · Google Play)

  • Mushi Mushi — 虫虫

    For when the user knows something's wrong but the monitoring tools still show green. (GitHub)

  • Bento — 弁当

    An AI workspace organised around one loop — plan, make, review, ship — in warm paper tones. (GitHub)

  • How to Talk to Girls — 会話の練習

    Practice for the conversations that get tense — rehearse the hard chat, get your reply scored, before it counts.
