Methodology and sourcing behind the figures shown above.
People-based intent audiences
No explicit market-size or CAGR figures were present in the provided search results. I therefore estimated the people-based intent audiences market as a niche subset of the broader intent-data/identity-resolution/data-as-a-service markets. Evidence from the results shows active product launches (Demandbase Person-Based Intent), multiple vendors and use cases (Visitor InSites, LinkedIn/Delivr.ai descriptions), and provider-scale signals (individual-level observations in the tens-to-hundreds of millions), indicating meaningful addressable demand. Based on typical proportions of niche segments within the larger audience-data and CDP/identity markets, and current adoption momentum, I estimate a global market size around $1.5B and a medium-term growth potential of ~12% CAGR.
Website visitor identification and lead generation
Estimate derived from observed vendor ecosystem and adoption signals in the supplied results (major players: ZoomInfo, Clearbit, Leadfeeder, Lead Forensics, Leadpipe and many niche providers), plus an internal mapping of this niche as a small but rapidly growing subset of global martech/intent-data spending. Evidence in the results shows large addressable signals (e.g., ZoomInfo’s IP-to-organization mapping, Leadfeeder’s customer base and industry positioning, Leadpipe/others reporting high match-rate improvements and strong conversion impacts), indicating meaningful monetizable demand. Conservatively model this segment as low-single-digit percent of global martech/intent-data spend, producing an estimated market size of roughly $2.0B and a growth profile driven by increased ABM/intent adoption, server-side/first-party tracking shifts, and AI enrichment — consistent with a mid-teens to low-teens CAGR; a conservative midpoint of ~12% CAGR is used here.
Agency-led audience activation
Estimated by aggregating adjacent market figures in the search results (media buying and experiential marketing) and treating agency-led audience activation as a specialist subset. Fact.MR reports media buying at ~USD 86.1B (2026) and BRI reports experiential marketing at ~USD 56.69B (2026) — combined ~USD 142.8B of relevant agency-managed activation spend. Assuming agency-led audience activation represents ~15–20% of that combined addressable activity (platform/data/activation services, CRM and cross-channel activation), the midpoint yields ~USD 25.7B. Growth potential (CAGR ~8%) is set above mature experiential (BRI 2.8%) and near/above media buying services (Fact.MR 6.9%), reflecting faster expansion for data-driven audience activation, programmatic/retail-media acceleration, and CRM integration.
- Global Experiential Marketing Agency Market is estimated to be valued at approximately USD 56.69 Billion in 2026.
- Base Value(2025): 80.5 Bn • Estimated Value(2026): 86.1 Bn • CAGR (2026 - 2036): 6.9%.
- $616 billion was spent on digital advertising globally in 2022; set to pass $1 trillion by 2027.
- Advertising agencies industry: CAGR of 2.7% since 2019, expected total $70.1 billion in 2024.
Intent-driven demand generation
Primary basis: a published market projection for the global B2B demand generation services market (~$15B by 2033) was used as the top-level market. Intent-driven demand generation (first- and third-party intent signals, personalized distribution, automated engagement) is a growing subset of that market; assuming it represents roughly 20% of B2B demand-generation services today yields an estimated current market of about $3.0B. Growth potential (≈10% CAGR) reflects continued adoption of intent data, personalization and AI in B2B demand programs and the headline projection for the broader B2B demand-gen market.
