What's the one slide that makes or breaks a pitch deck? After designing presentations for clients in 45+ countries, my answer is the problem slide. If investors don't feel the problem in the first 10 seconds, every slide after it has to work twice as hard. Most decks I redesign have the same issue: too much text, no clear focus, and the key number hidden at the bottom. What's your pick: problem, traction, or the ask? Curious to hear from founders and fellow designers.
