How two rounds of structured discovery — qualitative outreach and a head-to-head ad test — found the real entry point for Emitroll before a single line of product code was written. --- ### 06. Forum Posts as Validation Evidence - Category: Product / Validation - Date: June 7, 2026 - Read time: 15 min read - URL: https://francisj2nd.cv/cs/forum-posts-as-signal Primary outreach to US freight carriers stalled.
