What’s Keeping You Up at Night?

Great founders ask great questions.

Every startup begins with a question. But the most important questions often come later—when you’re in the thick of it, when things break, when you’re stuck. That’s where 9others comes in.

Since 2011, 9others has hosted over 500 private founder dinners in 45+ cities worldwide. At every meal, ten entrepreneurs gather and are asked just one question: What’s keeping you up at night?

Over 5,000 founders have shared real, raw, and sometimes painful challenges at these tables. What emerged wasn’t just advice—it was a pattern of thinking, a set of questions and behaviours that helped the most successful founders push through.
