Internal vs. external growth

Internal/organic growth a business grows using its own resource increase the scale of its operations and sales revenue.

External growth a business grows by collaborating with, buying up or merging with another firm.

Organic growth can be achieved by selling new products, increasing production and sales through marketing or finding new markets. For most businesses internal growth is slow, but it does so at less risk than external growth and can be financed through internal funds. External growth is a much quicker alternative to organic growth. External growth can be a quick way to reduce competition in a market, gain economies of scale, gain entry into foreign markets or achieve synergy.

The growth and expansion of a business are pivotal to its long-term success and sustainability. Businesses typically pursue growth through either internal (organic) or external means, each path offering distinct advantages, challenges, and strategic implications. Understanding the nuances between internal and external growth is crucial for IB Business & Management students, as it provides insights into how companies scale their operations, enter new markets, and enhance their competitive positioning. This comprehensive analysis explores the concepts of internal and external growth, supported by industry examples to illustrate their practical application and impact.

Internal (Organic) Growth

Definition: Internal growth, also known as organic growth, refers to the process of expanding business operations and increasing sales revenue using the company’s own resources, without resorting to merging with or acquiring other firms. This growth strategy focuses on enhancing the core competencies of the business through investment in technology, product development, market expansion, and operational efficiencies.


  • Control: Maintains control over the growth process without diluting ownership or compromising the company’s culture and values.
  • Brand Consistency: Ensures consistent brand message and customer experience as the company expands.
  • Gradual Expansion: Allows for a more manageable pace of growth, reducing risks associated with rapid expansion.


  • Resource Limitations: Growth is limited by the company’s own financial and operational resources.
  • Slower Growth Rate: Organic growth typically takes longer to achieve significant increases in market share or revenue.
  • High Competition: Relies on the company’s ability to innovate and compete in the market without the benefits of synergies from mergers or acquisitions.

Industry Example: Google has demonstrated significant internal growth by continually innovating and expanding its range of products and services. Starting from its search engine, Google organically grew by developing new offerings such as Gmail, Google Maps, and Google Drive, significantly increasing its market presence and revenue streams.

External Growth

Definition: External growth, or inorganic growth, involves a business expanding its operations through collaborations, acquisitions, mergers, or partnerships with other firms. This strategy enables companies to quickly gain market share, access new customer bases, and achieve synergies that can enhance efficiency and innovation.


  • Rapid Expansion: Enables quicker scaling of operations and market presence compared to organic growth.
  • Access to New Markets: Provides immediate access to new geographical markets and customer segments.
  • Operational Synergies: Can achieve cost savings and efficiencies through the consolidation of operations, technologies, and resources.


  • Integration Challenges: Merging different corporate cultures, systems, and operations can be complex and costly.
  • Higher Risk: Involves significant upfront investment and financial risk, especially in the case of acquisitions.
  • Potential for Dilution: Shareholders may face dilution of ownership, and the company’s culture may be compromised.

Industry Example: Disney’s acquisition of Pixar, Marvel, and Lucasfilm are prime examples of external growth, allowing Disney to rapidly expand its portfolio of intellectual properties, enter new markets, and leverage synergies across its entertainment and media businesses.


Both internal and external growth strategies offer viable paths for business expansion, each with distinct advantages and considerations. While internal growth focuses on leveraging a company’s inherent strengths and resources for gradual expansion, external growth offers a pathway to rapid scaling, market entry, and operational synergies through strategic alliances and acquisitions. The examples of Google’s internal growth through product innovation and Disney’s external growth through strategic acquisitions illustrate how businesses can effectively leverage these strategies to enhance their market position and achieve long-term success. For IB Business & Management students, understanding these growth strategies is essential for analyzing business operations and developing strategic plans that align with a company’s goals and resources.
