TAMLabs by Orca Labs
The only Excel-native market sizing platform built on SEC-verified company data and a proven enterprise TAM/SAM methodology
Stop guessing. Start closing.
TAMLabs gives GTM leaders, founders, and revenue teams a ready-built, data-backed market sizing engine — directly inside Microsoft Excel. No data science team required. No stitching together spreadsheets from scratch. No questionable data sources
What makes TAMLabs different:
Most market sizing tools give you a framework and leave you to find your own data. TAMLabs ships with both — a battle-tested TAM/SAM methodology AND a pre-loaded universe of public company data sourced directly from SEC filings. The result is a target list that's defensible in a board meeting, credible in a sales deck, and actionable in the field on day one
Why it works:
The underlying TAM/SAM methodology was developed and validated across decades of enterprise go-to-market strategy work — the same framework used to size markets for $1B+ SaaS companies and PE-backed growth initiatives. You're not buying a template. You're buying a proven system
Who it's for:
- AI startups building their first enterprise target list
- GTM and revenue leaders who need to justify market entry to a board or investor
- Strategy and corporate development teams sizing acquisition opportunities
- Sales and marketing ops teams building ICP-driven account lists
- Value engineers building their customer business cases
