Superhuman's Product-Market Fit Framework: Measuring and Optimizing for Success

Rahul Vohra, CEO of Superhuman, details how he developed a measurable framework for achieving product-market fit by identifying a leading indicator metric and implementing a four-step optimization process. The framework centers on the 40% threshold of users responding "very disappointed" if they could no longer use the product, enabling systematic improvement rather than relying on post-launch signals.
