The challenge

Reports and landing pages were made by hand, and the routine work was a burden on the team.

✓Ad reports: Google Apps Script pulls Meta Ads data, the Claude API analyzes it, and a report in Japanese is written automatically.

✓A Make.com and Claude API pipeline that runs from data collection to analysis and distribution.

✓Repeatable workflows for ad copy, landing page structure and email copy.

✓Scheduled delivery of a daily newsletter.

✓An in-house AI coaching app, built with the Anthropic API and Cursor, which we operate ourselves.

✓Weekly ad report: from 3–4 hours to about 20 minutes

✓First drafts of landing pages and ad copy: 60–70% less time

✓About 70% of routine work turned into systems.

The time saved goes into strategy, analysis and A/B test ideas.
