I built about 10 to 12 projects across different spaces, most of them never made it to production. With Lyric AI video generators or automating job applications, I didn't really know what the end user wanted or why the current softwares weren't living up to their hype. With the Amazon world I already understood from A to Z what problems new sellers were running into.
Build the tool you wish you had — graveyard projects came from foreign domains
Hassam's failure pattern was building for domains he didn't operate in — every AI-video and job-automation project died because he guessed at user pain.
