Bottom-Up Analysis
Last updated
Quick Answer
A market sizing approach that builds estimates from actual customer data and unit economics rather than top-down market reports.
What it is
Bottom-up analysis calculates market opportunity by starting with specific, measurable inputs: number of potential customers, expected conversion rates, average revenue per customer, and expansion potential. VCs prefer this to top-down TAM claims.
In Practice
Instead of citing a $50B TAM from Gartner, the founder showed: 50,000 target companies × 12% expected penetration × $50K ACV = $300M serviceable revenue opportunity.

VC Beast Take
Any startup can claim a $100B TAM. The ones that can build it from the bottom up actually understand their market.
