in Market Development?
When developing markets for your products or services, it is essential to understand the total market size and set strategic goals. TAM/SAM/SOM are cited as effective metrics for market analysis.
However, while many understand the importance of visualizing TAM/SAM/SOM, many may also be unsure of the specific steps to take.
In this article, we introduce methods for market analysis using TAM/SAM/SOM, as well as how to calculate your company's actual TAM.

The metric representing the overall revenue opportunity for a product or service is called the Total Addressable Market (TAM).
It is often described as the maximum market size available, providing an efficient way to list potential customers.
The portion of the TAM that represents your target market is called the Serviceable Available Market (SAM).
The portion of the SAM that can be reached through your company's specific sales activities is called the Serviceable Obtainable Market (SOM).
Since the SOM can be interpreted as the target market share for your product or service, it is frequently used to calculate corporate sales targets.
Accurate corporate data is essential for understanding TAM, SAM, and SOM.
Efficiently calculating TAM is important, but it requires having access to a comprehensive corporate database as a baseline.
Here, you can calculate your company's TAM by utilizing LBC, a corporate database independently built by uSonar that covers 12.5 million locations nationwide.

Furthermore, to perform the necessary filtering to create SAM and SOM, it is crucial to understand the corporate characteristics of both your current and potential customers.
The accuracy of your filtering will change significantly depending on whether you can select companies based not only on industry or number of employees, but also on axes such as "business challenges" and "interests."
Additionally, the freshness of the information used for filtering is also critical.
