What had to change
Brand discovery is moving from ranked links to generated answers. Teams could see traffic changing, but they had no dependable way to see where their brand appeared, which sources shaped the answer or how that visibility changed across AI platforms.
The decisive move
I reduced that broad question to one useful workflow: define the prompts that matter, run them consistently across the major answer engines, preserve the response evidence and turn every mention into a comparable signal instead of another opaque dashboard number.
What the build covered
The product combined prompt management, multi-provider collection, mention and citation analysis, saved evidence, reporting and account workflows in one SaaS experience. Product decisions, interface design and engineering stayed in the same loop because I owned the build end to end.
Why it matters
MentionRank launched as a working AI-visibility product and was transferred after the founder phase. It demonstrates the full path from identifying an emerging market change to shipping, operating and handing over a focused product.
