The article introduces the T-Score methodology, a quantitative framework designed for B2B founders to determine the best timing for launching products. It emphasizes that market timing isn't about intuition but about analyzing specific data points: Market Readiness Score, Defensibility Index, and Customer Acquisition Cost (CAC) Volatility. By calculating these variables, founders can arrive at a T-Score that indicates whether they should launch or wait. A T-Score below 8 suggests it’s too early, while scores between 12-20 are ideal for entering the market. The article highlights the risks of early launches through the example of Pebble, which, despite raising over $50 million and having a solid product, failed due to poor timing. Historical data reveals that true pioneers often struggle in the long run, with a failure rate of 47% and an average market share of just 10%. In contrast, companies that enter the market later—after pioneers have paved the way—often see greater success, achieving a 78% success rate when their T-Scores fall within the optimal range. The framework also includes a quick calculator for founders pressed for time, allowing them to make preliminary decisions efficiently. Overall, the T-Score methodology aims to reduce the uncertainty around timing decisions, transforming weeks of strategic debate into actionable insights in just a few hours. By relying on data instead of gut feelings, founders can better position themselves within the market's evolving landscape.
