Kill Rate

The percentage of new business opportunities, leads, or projects that a company or investor decides not to pursue — a measure of selectivity and decision-making discipline.

Kill rate applies beyond investing. Sales teams track the percentage of leads they disqualify early in the process — a high early kill rate means better qualification and less time wasted on deals that will never close. Project managers kill low-ROI projects to protect capacity for high-priority work. Product teams kill features that don't meet the threshold for user value or strategic fit.

The discipline to kill decisions early — before significant time, money, and emotional investment have been sunk — is one of the hardest skills in business. Sunk cost fallacy makes it psychologically painful to abandon something you've already invested in. Organizations with strong kill-rate discipline actively counteract this by reviewing opportunities against forward-looking criteria, not backward-looking investment justifications.

The best investors and businesses say no far more often than they say yes. A high kill rate isn't failure — it's discipline. Warren Buffett calls it his 'punch card' philosophy: you only get 20 great investments in a lifetime, so each yes has to be exceptional. Every no protects the quality of every yes.

Real world: Top-tier venture capital firms like Sequoia and Andreessen Horowitz receive thousands of pitches annually and invest in fewer than 1% of them — a kill rate above 99%. That extreme selectivity isn't arrogance; it's the math of venture investing. A single exceptional investment can return the entire fund. Spreading capital across mediocre deals dilutes returns even if most of those deals turn out fine.

💡 A high kill rate is a sign of discipline, not failure — the ability to say no quickly and confidently protects your best resources for the opportunities that actually deserve them.
