They would consider factors like company size, geographic reach, and technological readiness. If there are 5 million potential business customers worldwide, and their solution is priced at an average of $5,000 annually per customer, their TAM would be $25 billion. This figure helps them understand that even capturing just 1% of this market would result in $250 million in annual revenue. The company can then develop targeted marketing campaigns for specific segments within this TAM, such as small e-commerce businesses or mid-sized manufacturing firms, allocating resources proportionally to the most promising opportunities while setting realistic sales targets for their teams. ## You should also read: [Total Audience Measurement](/glossary/total-audience-measurementx)[Touches](/glossary/touchesx)[Touchpoints](/glossary/touchpointsx)[Trade Shows](/glossary/trade-showsx)[Trademarks](/glossary/trademarksx)[Trigger Marketing](/glossary/trigger-marketingx)[Triggered Email](/glossary/triggered-emailx) ## Why teams choose Derrick.
