Yusuke Takita

CEO at M&A Navi, inc. building AI-native back-office automation. Ex-engineer turned operator. I build CLI tools and AI agents for M&A, accounting, tax, and internal operations, then open-source the parts that can be shared.

TypeScript Python Go Ruby COBOL Delphi Java

Start here

  • M&A Navi — Japan's online M&A matching marketplace.
  • mission — Quality-gated autonomous mission loop (plan → execute → review → score → iterate) for Claude Code and Codex.
  • freee-mcp — Official MCP server for freee's accounting API (contributor).
  • ghostty-layout — Swift CLI to apply split layouts to the Ghostty terminal.

What I'm building

At M&A Navi, inc.

  • M&A Navi — Japan's online M&A matching marketplace.
  • Deal-management platform — a cloud workspace for advisors to run M&A deals end-to-end.
  • SmartDD — AI-assisted financial due diligence that drafts investment memos from raw data.

Open source

  • mission — Quality-gated autonomous mission loop for Claude Code and Codex: plan, execute, peer-review, score, and iterate until a threshold passes.
  • freee-mcp — Contributor to freee's official MCP server for their accounting API.
  • ghostty-layout — Swift CLI to apply split layouts to the Ghostty terminal.
  • xai-cli — xAI / Grok search CLI for analyzing X posts.
  • slamy — Slack MCP server and CLI.
  • noty — Notion CLI, library, and MCP server for TypeScript.
  • google-ads-cli / meta-cli — Ads operations CLIs for work automation.

I build internal agent workflows for back-office automation: Slack operations, X automation, accounting and tax workflows, and audit-friendly internal controls.

What I care about

AI × M&A · accounting & tax automation · internal controls and audit trails · agents that do real back-office work, not demos.

I build the tools I wish existed, then open-source them. A CEO who can prototype doesn't wait for a roadmap.
