HookLens

Alex, Mihir Kanzariya, Ilya Lisin, Alexey Glukharev, and Abhinav Ramesh looked at the advertising industry and realized something obvious most people miss: ads don't fail randomly—they fail in one of three places. The hook gets ignored. The body loses attention. The call-to-action falls flat. So they built HookLens, a tool that tells you exactly which of those three elements is killing your conversion.

Most ad optimization tools give you a soup of metrics and let you figure it out. HookLens is different—it narrows it down to one of three things. Hook. Body. CTA. No ambiguity, no guesswork. Just: your ad fails here. It's the kind of simple, obvious-in-retrospect tool that makes you wonder why it didn't exist sooner. The kind of tool you'll use once and then wonder how you ever ran ads without it.

This is what happens when builders actually use the products they complain about. Five founders who got tired of tweaking creative without knowing what actually moved the needle. Welcome to the era of precision advertising.
