Business & Strategy 6 minute read Updated May 16, 2026

Summary

Launching a high-tech product is a risky endeavor. While startups often gain initial traction with technology enthusiasts and visionaries, they frequently fail to convert that early success into mainstream market dominance. This gap is known as “The Chasm.” Adapting the Diffusion of Innovations theory, Geoffrey Moore explains that technology adoption follows a bell curve with five distinct groups: Innovators, Early Adopters, Early Majority, Late Majority, and Laggards. The most disconcerting gap lies between the Early Adopters (visionaries who want disruptive change) and the Early Majority (pragmatists who want proven, reliable improvements). Because these groups have fundamentally different psychographic profiles and expectations, the marketing strategies that work for the former often fail with the latter. To cross this chasm, Moore argues companies must abandon the generalized approach of the early market. Instead, they must adopt a “D-Day” strategy by concentrating all resources on a single, accessible market niche. By creating a complete solution for the pragmatic customer in this specific segment, establishing dominance, and building word-of-mouth validation, a company can create a bandwagon effect that eventually expands into the broader mainstream market.
