The “catfish effect” describes how the presence of a strong competitor or external challenge can stimulate a stagnant group to become more active, innovative, and productive. The metaphor is commonly linked to a Norwegian fishing story in which live catfish were reportedly placed among sardines during transportation, keeping them moving and helping maintain their condition. Whether treated as literal history or business folklore, the idea has become a useful way to understand competition and motivation in organizations.
In marketing, the catfish effect explains how competition can prevent companies from becoming complacent. When a business enjoys a dominant market position for a long period, it may gradually rely on familiar products, established advertising methods, and loyal customers. A new competitor can disturb this comfortable situation. For example, when a startup introduces a cheaper product, a more convenient digital service, or a distinctive brand experience, established companies may be forced to reconsider how they attract and retain customers.
The catfish effect can therefore become a powerful marketing technique, although it is better understood as a competitive strategy than as a single promotional method. Companies can deliberately create competitive pressure by entering new markets, launching innovative products, targeting underserved customer segments, or repositioning their brands against emerging rivals. Even businesses that already lead their industries can use simulated competition, such as internal innovation challenges, alternative product teams, or experimental campaigns, to prevent marketing strategies from becoming outdated.
Competition also encourages marketers to pay closer attention to consumers. When customers have more choices, companies must understand changing preferences, improve customer experiences, personalize communication, and demonstrate clearer value. Digital marketing has intensified this process because consumers can quickly compare prices, reviews, features, and brands online. Social media and e-commerce have also lowered barriers for smaller companies to challenge established businesses. As a result, the “catfish” may appear suddenly in the form of a startup, viral brand, technological innovation, or changing consumer trend.
A classic example can be seen when disruptive companies enter established industries. Their unconventional pricing, technology, distribution methods, or branding can force traditional competitors to improve their digital platforms, revise pricing, accelerate product development, or communicate more effectively with customers. The resulting competition can benefit consumers through greater choice, improved products, and better service.
However, the catfish effect must be managed carefully. Excessive competitive pressure can produce fear, burnout, unethical behavior, and destructive internal rivalry. Marketing teams need psychological safety as well as ambitious goals. Leaders should treat competition as a stimulus for learning rather than a reason to punish failure.
Ultimately, the catfish effect offers an important lesson for modern marketing: comfort can weaken innovation, while constructive competition can restore energy and creativity. Companies that continually monitor competitors, anticipate disruption, listen to customers, and encourage experimentation are better positioned to remain relevant. The strongest organizations do not merely react when a “catfish” appears; they build cultures that keep moving even when the market seems calm.The Catfish Effect in Marketing and Business
