I therefore estimated a conservative addressable market of roughly $2 billion (global annual vendor revenue) today, reflecting a small share of marketing-measurement budgets and specialist SaaS/consulting services. Growth potential is higher than traditional capital equipment measurement markets because of SaaS delivery, validation demand, and privacy-driven measurement needs; I estimate a ~12% CAGR over the coming years.
