The significance of “product-market fit” in tech startups lies in its potential to validate a startup’s value proposition. Achieving product-market fit indicates that a product meets the needs of its target audience, leading to increased traction, customer satisfaction, and ultimately sustainable growth. It provides essential feedback for iterations and improvements, guiding startups in refining their offerings. Without this fit, startups often struggle with scaling, customer retention, and profitability, making it a crucial milestone in the entrepreneurial journey.
