SOM (Serviceable Obtainable Market)

1. Serviceable Obtainable Market (SOM) - A Comprehensive Guide

The **Serviceable Obtainable Market (SOM)** is a critical concept in business strategy, particularly for startups and companies launching new products or entering new markets. It represents the portion of the Total Addressable Market (TAM) that a company can realistically reach with its current business model, resources, and capabilities. Understanding your SOM is vital for accurate forecasting, resource allocation, and attracting investment. This article provides a detailed exploration of SOM, its calculation, importance, and how it differs from related market sizing concepts.

1. 1. Understanding Market Sizing Concepts: TAM, SAM, and SOM

Before diving deep into SOM, it’s crucial to understand its relationship with two other key market sizing metrics:

• **Total Addressable Market (TAM):** This represents the *total* market demand for a product or service. It’s the theoretical maximum revenue a business could generate if it achieved 100% market share. TAM is often a top-down estimate, based on overall industry revenue and market statistics. It answers the question: “How big could this market be *in its entirety*?”
• **Serviceable Available Market (SAM):** The SAM is the segment of the TAM that your product or service *specifically* addresses. It’s a more refined estimate than TAM, considering the geographic locations, customer segments, and specific needs that your business caters to. SAM narrows down the focus to the markets you *could* realistically serve. It answers: “How much of the TAM are we *geographically and demographically* equipped to serve?”
• **Serviceable Obtainable Market (SOM):** As mentioned previously, SOM represents the portion of the SAM that you can realistically capture given your current business model, resources, competition, and marketing efforts. It’s the most practical and actionable market size metric. It answers: “How much of the SAM can we realistically *capture*?”

Think of it as concentric circles: TAM is the largest circle, containing SAM within it, and SAM containing SOM within it.

Market Analysis is the foundation for determining these values.

1. 1. Why is SOM Important?

Calculating and understanding your SOM is crucial for several reasons:

• **Realistic Goal Setting:** SOM provides a realistic benchmark for revenue projections and growth targets. Setting goals based on TAM alone can be overly optimistic and lead to disappointment.
• **Investor Confidence:** Investors want to see a clear understanding of the market opportunity and a credible plan for capturing a significant portion of it. A well-defined SOM demonstrates that you’ve thought critically about your business and its potential. Financial Modeling relies heavily on accurate SOM estimates.
• **Resource Allocation:** Knowing your SOM allows you to allocate resources (marketing budget, sales team, product development) effectively. Focusing on a realistic target market maximizes your return on investment.
• **Strategic Focus:** SOM helps you identify your ideal customer profile and tailor your marketing and sales efforts to reach them. Marketing Strategy is directly influenced by the SOM.
• **Competitive Analysis:** Understanding your SOM forces you to analyze your competitors and their market share. This helps you identify opportunities to differentiate your product or service and gain a competitive advantage. Competitive Intelligence is key here.
• **Product Development:** SOM insights can inform product development decisions, ensuring that you’re building features and functionalities that appeal to your target market. Product Management relies on this information.
• **Business Plan Development:** SOM is a core component of any solid Business Plan.

1. 1. Calculating Your SOM: A Step-by-Step Guide

Calculating SOM can be complex, but here’s a step-by-step guide:

• • Step 1: Define Your Target Customer**

Be incredibly specific. Don’t just say “small businesses.” Instead, define your target customer by:

• **Industry:** (e.g., Restaurants, Healthcare, E-commerce)
• **Company Size:** (e.g., 1-10 employees, $1M - $5M revenue)
• **Location:** (e.g., United States, Europe, Specific Cities)
• **Job Title/Role:** (e.g., Marketing Manager, CEO, IT Director)
• **Specific Pain Points:** (e.g., Difficulty managing social media, High customer acquisition costs, Lack of data analytics)

• • Step 2: Determine Your SAM**

Based on your defined target customer, calculate the size of the SAM. This involves:

• **Market Research:** Use industry reports, market research databases (e.g., Statista, IBISWorld), and government data to estimate the total number of potential customers within your target segment.
• **Geographic Filtering:** Narrow down the market based on your geographic focus.
• **Demographic Filtering:** Further refine the market based on demographic characteristics relevant to your product or service.

• • Step 3: Assess Your Reach & Capabilities**

This is the most critical and often the most challenging step. Consider the following factors:

• **Sales & Marketing Capacity:** How many sales representatives do you have? What is your marketing budget? What is your customer acquisition cost (CAC)? Customer Acquisition Cost is crucial for SOM calculation.
• **Distribution Channels:** How will you reach your target customers? (e.g., Direct sales, Online advertising, Resellers, Partnerships)
• **Competition:** How many competitors are targeting the same market segment? What is their market share? Porter's Five Forces can help assess the competitive landscape.
• **Product/Service Differentiation:** What makes your offering unique and compelling? How does it compare to the competition?
• **Brand Awareness:** How well-known is your brand within your target market?
• **Geographic Limitations:** Are there any geographic areas you cannot effectively serve?
• **Technological Constraints:** Do your technological capabilities limit your reach? (e.g., language support, compatibility with specific systems)
• **Regulatory Environment:** Are there any regulatory hurdles that could limit your access to the market?

• • Step 4: Calculate Your SOM**

There are several ways to calculate your SOM:

• **Bottom-Up Approach:** Estimate the number of customers you can realistically acquire within a specific timeframe (e.g., one year) and multiply that by your average revenue per customer. This is often the most accurate method.
• **Top-Down Approach:** Start with your SAM and apply a realistic market penetration rate based on your reach and capabilities. For example, if your SAM is $100 million and you estimate you can capture 5% of the market in the first year, your SOM would be $5 million.
• **Combined Approach:** Use both bottom-up and top-down approaches to validate your estimates.

• • Formula:**

SOM = SAM x Market Penetration Rate

Where:

• Market Penetration Rate = (Number of Customers You Can Acquire / Total Number of Customers in SAM)

1. 1. SOM vs. SAM vs. TAM: A Practical Example

Let’s say you’re launching a cloud-based accounting software specifically designed for small restaurants in the United States.

• **TAM:** The total revenue of the accounting software market in the US is $10 billion.
• **SAM:** The total revenue of accounting software used by restaurants in the US is $1 billion. (This is a segment of the TAM).
• **SOM:** You have a small sales team and a limited marketing budget. You estimate you can realistically acquire 500 restaurant customers in the first year, and your average revenue per customer is $2,000. Therefore, your SOM is 500 x $2,000 = $1 million.

1. 1. Common Mistakes to Avoid When Calculating SOM

• **Overestimating Market Penetration:** Be realistic about how quickly you can acquire customers. Don’t assume you’ll achieve a high market share overnight.
• **Ignoring Competition:** Failing to account for the competitive landscape can lead to overly optimistic SOM estimates.
• **Using Vague Definitions:** Clearly define your target customer and the specific market segment you’re addressing.
• **Relying on Outdated Data:** Use the most recent market research data available. Data Analysis is essential for accurate estimates.
• **Ignoring Geographic Limitations:** Don't assume you can serve all geographic areas equally effectively.
• **Failing to Regularly Update SOM:** Market conditions change. Revisit and update your SOM calculation periodically.

1. 1. SOM in Different Business Contexts

• **Startups:** For startups, SOM is *especially* critical. It’s often the primary metric investors use to assess the viability of the business.
• **New Product Launches:** When launching a new product, SOM helps determine the potential revenue and profitability of the product line.
• **Market Expansion:** When expanding into a new geographic market, SOM helps assess the opportunity and the resources required for success.
• **Strategic Partnerships:** SOM analysis can help evaluate the potential benefits of strategic partnerships.

1. 1. Advanced Considerations and Tools

• **Cohort Analysis:** Analyzing customer behavior based on acquisition date can refine SOM estimates.
• **Churn Rate:** Account for customer churn when calculating long-term SOM. Customer Retention impacts SOM.
