A demo of Clu, the Cleanlist AI agent, doing this for a whole list. Asked: Find Heads of Data or Analytics, 2-5 years in the role, at Series C+ software companies with 201-1,000 people that raised in the last 12 months. US or Canada. Skip HubSpot customers. Verify their emails. Clu runs the tools, asks for confirmation before spending credits (Find work emails for 25 leads on Data leaders, Series C+, 25 credits), fills the list row by row and reports: 25 leads, 24 verified emails. One is a catch-all, so I marked it risky.

What a TAM calculator does
A TAM calculator estimates your Total Addressable Market: the full revenue opportunity if you captured 100% of your target segment. Enter industry, geography, and company size, and this free tool returns TAM, SAM (typically 40-60% of TAM), and SOM (a realistic year-one slice), plus how many decision-maker contacts are reachable in that segment.

How does this tool work?
Total Addressable Market (TAM) is the total revenue opportunity available if you captured 100% of your target market. For B2B sales teams, understanding TAM helps prioritize which segments to pursue, how much to invest in outbound, and whether a market is large enough to justify a dedicated go-to-market motion.
This free calculator estimates your TAM, SAM (Serviceable Addressable Market, the portion you can realistically serve), and SOM (Serviceable Obtainable Market, what you can capture in year one). It also shows how many decision-maker contacts exist in your target segment and how many are reachable with verified contact data through Cleanlist AI's 25+ provider waterfall.

Frequently asked questions
Short answers about the TAM Calculator: what it checks, what it costs and where it stops.
All free toolsWhat is TAM, SAM, and SOM?
TAM (Total Addressable Market) is the total revenue opportunity if you had 100% market share. SAM (Serviceable Addressable Market) is the portion of TAM you can realistically serve with your current product and go-to-market, typically 40-60% of TAM. SOM (Serviceable Obtainable Market) is what you can realistically capture in year one, usually 5-10% of SAM. Investors and sales leaders use these metrics to assess market opportunity and set realistic revenue targets.
How accurate is this TAM calculator?
This calculator uses industry averages and public market data to provide directional estimates. It is useful for quick sizing, pitch decks, and planning conversations. For precise TAM analysis, you should build a bottom-up model using your specific ICP criteria, Cleanlist AI's People Search can help you count exactly how many contacts match your target filters.
How do I find contacts in my TAM?
After estimating your TAM, use Cleanlist AI's AI-powered People Search to find actual contacts matching your criteria. Describe your ICP in natural language, industry, company size, job titles, geography, and Cleanlist AI returns verified contacts with emails (98% accuracy) and phone numbers (85% coverage) from 25+ data providers.
