Tools
Software I built
for operators
like me.
I run ten businesses across Japan. These are the tools I built to do it, and now they're yours. Each one solves a problem I hit repeatedly and couldn't find a good answer for.
RedditReach
Build authority where your customers already look.
Monitor subreddits for keyword-matched posts, generate contextual replies using Claude, Gemini, and ChatGPT, and schedule engagement that looks natural. Staggered timing, cross-post detection, best-time analytics. Built for operators who want inbound without paying for ads.
TetsuClaw
A work operating system for Japan.
Eleven specialist AI agents in one Telegram bot covering tax, scheduling, transit, real estate, legal intake, content, research, and more. Built on Claude, tuned for English-speaking operators navigating Japanese corporate infrastructure.
Japan Money Tracker
Organize your money for Japanese tax filing.
AI-powered receipt scanning, multi-currency expense tracking, and 確定申告-ready categories. Paste OCR text or upload photos and Claude extracts dates, amounts, vendors, and tax rates automatically. Syncs to Airtable and Google Drive.
Hitoe
One canonical list of your people.
Your members are scattered across Stripe, Luma, Mailchimp, Google Sheets, and your inbox. Hitoe rectifies and normalizes contacts across platforms into a single source of truth. Stop guessing who's actually in your community.
