How We Work – The CI Way
We think as individuals and invest as a team. Our goal is never consensus — it is the best decision. Titles do not determine whose ideas matter. The best argument wins.We distinguish bad decisions from bad outcomes. Good decisions sometimes produce disappointing results, and poor decisions sometimes get lucky. We grade the quality of the thinking.Courage is a job requirement. When we believe an investment is wrong, we say so — in the room, on the record.Founders come first. Within the bounds of good judgment, we go out of our way to help entrepreneurs. We are allies, not obstacles.Humility and institutional memory. Every investment starts with a blank page. We are often wrong, so we stay open. We capture what each deal taught us so the next decision is better than the last.
