10 Things Founders Get Wrong In Their Pitch Deck

​Your pitch makes sense to you. The question is whether it makes sense to an investor.

​In this session, we'll run the 10 most expensive narrative mistakes founders make in their pitch deck, diagnosed against a live VC rubric built from real investor signal. You'll see exactly where decks lose the room and leave with one concrete fix you can make before your next meeting.

​This session includes access to a free Narrative Diagnostic assessment.
