Case Studies

Measured results at the businesses that use what we build. Every figure lists its comparison conditions, and estimates are kept separate from actual results.

Case Study

KaitoriAI

Kouka Kaitori Takagai (Futatabi Inc.)

Industry
Buyback and resale
Timeline
In production since July 2026 (built in as little as one week)
Challenge
LINE followers rarely reached the appraisal request step. After-hours inquiries were lost. Staff spent hours on intake and manual data entry.
What we delivered
On the client's official LINE account, an AI bot collects item details, condition, and photos in conversation, structures them, and notifies staff. Operating hours and hand-off to humans are configured, and price and buy/no-buy decisions remain with store staff.
