How to calculate TAM size
Describe your ICP to map your TAM
Add your ICP filters, such as industry, headcount, funding stage, and location. Sculptor scans Clay's B2B company data for every matching account.
Sculptor compiles the matched company list
Sculptor assembles a company list filtered by your exact ICP criteria, then waterfalls through 150+ providers to find a verified Head of Marketing email on rows where a match is returned.
Export your TAM with Head of Marketing emails
The finished table has company name and, for matched rows, a verified Head of Marketing email. Export to CSV, sync to Salesforce, or pipe into your outbound tool of choice.
Why Clay for calculating TAM size
One dataset for your full B2B TAM
Map every company that fits your ICP using Clay's B2B company database, filtered by industry, headcount, funding stage, tech stack, hiring activity, and location. No stitching together exports from multiple tools.
AI scoring that tiers every matched account
Claygent browses each company's site and job listings to assign ICP tier scores based on hiring signals, funding recency, and tech stack fit. Your TAM goes from a raw count to a prioritized, actionable list in minutes.
Waterfall enrichment for decision-maker contacts
Get verified emails for matched rows by running waterfall enrichment through 150+ providers, with credits charged only when a match is returned. Catch-alls and role inboxes are flagged before contacts reach your sequencer.
Auto-sync TAM to Salesforce and LinkedIn Ads
Push your scored TAM directly to Salesforce with ICP tier fields populated, and sync enriched audiences to LinkedIn Ads for multi-channel targeting. Your TAM stays live as Clay auto-refreshes accounts on a schedule.
This job has always been about creativity, despite how it might seem, and Clay enables me to answer more 'what if we could...' questions from our GTM teams than I ever could before.
Frequently asked questions
How does Sculptor calculate my total addressable market?
Sculptor queries Clay's Find Companies database of 40M+ records, filtering by the industry or region you specify, and returns every company that matches your ICP criteria. It then runs a waterfall enrichment across multiple contact providers to find a verified Head of Marketing email for each account, so you get a sized, contact-ready TAM list in one step.
How accurate is the company and contact data in my TAM list?
Clay's waterfall enrichment lifts contact coverage to 85-95% compared to 60-75% from a single provider. In Clay's own benchmarks, top work-email providers score 94-97% accuracy on verified addresses. Firmographic data (industry, headcount, geography) lands around 80-88% accuracy across providers, and Clay's multi-source approach fills gaps that any one database misses.
Can I build a TAM list for thousands of companies at once?
Yes. Sculptor generates your full TAM table in bulk. Start with 200-500 rows to validate ICP fit, then scale to thousands. You can also paste a domain list or upload a CSV to enrich an existing account list. Push the final output directly to HubSpot or Salesforce, or export as a CSV for further analysis.
Is it legal to collect company data for TAM sizing?
Company-level firmographic data (industry, headcount, revenue) is generally not considered personal data under GDPR or CCPA. When you add individual contacts like a Head of Marketing email, GDPR's legitimate interest basis (Article 6(1)(f)) applies in the EU, and California's CCPA now covers B2B work emails after the exemption expired in January 2023. Penalties under CCPA reach $7,988 per intentional violation.
