Total Addressable Market

Definition

Total Addressable Market (TAM) is the total revenue opportunity available for a product or service if it achieved 100% market share. Investors and operators use TAM to size the potential of a business, evaluate growth runway, and compare sector opportunities.

Context

In Ep. 1, Karl Rectanus references TAM twice when describing LearnPlatform's strategic positioning. He notes that education "had a massive TAM" that influenced the company's decision to remain focused on the sector. Karl also argues that impact-centered practices — such as eliminating bias and serving underrepresented populations — expand TAM: "It's also a much larger TAM. It is directly aligned with, if you activate those who have been underrepresented or provide services and outcomes, you get better innovation, you get a more diverse workforce, you get a larger TAM to go and sell to."
