What is Market Sizing?

Market sizing quantifies potential revenue by estimating three nested buckets: Total Addressable Market (TAM) all possible spend worldwide; Serviceable Available Market (SAM) the slice you can reasonably reach; and Serviceable Obtainable Market (SOM) the share you can secure in the near term. Accurate sizing underpins fundraising, go-to-market strategy, and resource allocation.

Purpose & Strategic Value

1. Investor Confidence – Show a believable growth ceiling backed by first-party data, not hand-wavy analyst PDFs.
2. Roadmap Prioritization – Direct limited engineering bandwidth toward features that unlock the largest untapped spend.
3. Territory Planning – Assign sales and channel resources to regions with the fattest slices of SAM.
4. Pricing Optimization – Gauge budget ranges to set price points that capture value without leaving money on the table.
