The Chasm Model is a marketing framework developed by Geoffrey A. Moore in his book "Crossing the Chasm." It illustrates the challenges that new technologies face when transitioning from early adopters to the mainstream market. The model highlights a significant gap, or "chasm," between these two groups, emphasizing that strategies effective for early adopters may not resonate with the larger audience. To successfully cross the chasm, companies must tailor their marketing efforts to address the needs and concerns of the mainstream market. This often involves creating a compelling value proposition, building a strong customer base, and ensuring that the product meets the expectations of a broader audience.
