A new, simpler technology comes out that is cheaper but not as powerful as what big companies already sell. At first, only a few small customers buy it. How might this new technology still threaten the big companies in the future?

This scenario describes a classic case of disruptive innovation, a process by which a simpler, more affordable technology can eventually displace established market leaders, referred to as incumbent companies, even if it is initially less powerful. The new technology poses a threat by targeting underserved or unserved segments before moving into the mainstream market.

Initially, the new technology appeals to specific customer segments: either "low-end" customers or "new-market" customers. Low-end customers are those who are overserved by the existing, more powerful, and expensive products offered by big companies; they are willing to accept less performance for a significantly lower price and simpler functionality. New-market customers are individuals or small businesses who previously could not afford or access the complex, high-cost offerings of incumbent companies, making the new technology accessible to them for the first time.

Incumbent companies typically focus on continually improving their existing, high-performance products to meet the demands of their most profitable customers, often adding features that many customers do not fully utilize. This tendency causes them to "overshoot" the needs of simpler, less demanding customer segments. Consequently, they often dismiss the new, simpler technology because its initial performance is inferior for their core customers, and its lower price point does not align with their established profit models or revenue expectations. They perceive it as non-threatening because it does not compete for their high-value customers.

However, disruptive technologies possess a characteristic performance trajectory, meaning their capabilities and performance improve rapidly over time through continuous innovation, research, and development. As the technology matures, it becomes more capable, reliable, and "good enough" to satisfy the needs of an increasing number of mainstream customers, including segments of the incumbent companies' traditional clientele.

Crucially, the disruptive technology maintains its inherent cost advantage, often due to simpler design, different manufacturing processes, or a novel business model. When its performance capabilities converge with the needs of mainstream customers while retaining its significantly lower cost, it becomes a highly attractive alternative. At this point, the big incumbent companies face a significant challenge. Adopting the disruptive technology themselves would require fundamental changes to their established business models, potentially cannibalizing their existing, higher-margin products and alienating their most profitable customers. Their organizational structures, culture, and cost bases are typically optimized for higher-performance, higher-margin products, making it difficult for them to compete profitably at the lower price point and margin structure of the new technology.

The small companies pioneering the disruptive technology, having honed their product and business model within their initial niche, have built a robust customer base and a lower-cost operating structure. This provides them with a strong foothold from which to expand. They gradually move upmarket, offering increasingly capable products that still maintain a price advantage. This process leads to a steady erosion of the incumbent companies' market share and profitability, ultimately threatening their long-term viability and dominance.
