I have has been using Like I'm 5 for a few weeks (before even launch) :), and it finally made startup jargon feel approachable. Instead of drowning in buzzwords, she gets plain-English explanations that stick .. like a patient mentor sketching ideas on a napkin.
The Learning Worlds and short lessons helped her follow real conversations without constantly googling terms. She especially likes how it meets beginners where they are, without talking down to them. For anyone new to startups or switching careers, she would genuinely recommend it.
