Operations team manually contacting each customer 8+ times for price negotiation. Only 21.7% of bids were within the successful matching range (±1%).
"If we provide a bid slider with price range constraints and visualize transaction probability, market-aligned bids will increase from 21.7% to 60%."

Case Study 03 | NH44
Previous hypothesis: "If sellers see estimated settlement amount, sell-bid conversion will reach 40%"
Result: Jan 0%, Feb 11.11%, Mar 4.17% - Target not achieved
Cost calculator click rate gap: Buyers 68.29% vs Sellers 13.51% (5x difference) - Settlement info doesn't drive seller decisions.
Verification = "I'm selling" declaration
They haven't decided yet—just exploring
No middle ground between "interested" and "bidding"
Can't get demand info without submitting a bid
Seller exploration was never designed as a service
Core Value: "We'll tell you weekly if there's demand at your desired price"
Register desired price (no verification) → Weekly market report → Convert when ready
