DM a founder who has already built apps to join as co-founder

Zach, with childhood friend Henry, sent a DM to Blake, who had already built AI apps, and they formed Cal AI; later offered a COO role to Jake after seeing his work at StudyBuddy. Blake says he would not have replied to a copycat pitch.
