Methodology and sourcing behind the figures and links shown above.
B2B SaaS marketplace
Primary proxy is Labra’s cloud marketplace projection (cloud marketplaces to reach ~$100B in 2026 from $15B in 2023). I used that as a direct proxy for the B2B SaaS marketplace segment (marketplaces that connect buyers and vendors). Context from industry reports on the overall B2B SaaS market (Mordor, Fortune) — showing total B2B SaaS in the $390–497B range in 2025–2026 — supports treating marketplaces as a material sub-segment (~~20% of B2B SaaS in 2026 per Labra). The CAGR is the implied short-term CAGR from Labra’s 2023–2026 projection (≈88% annualized).
Buyer research and product comparison
Mapped the segment to the price-comparison/consumer comparison websites market. BusinessResearchInsights reports the price-comparison websites market size at USD 32.65 billion (2026) and projects growth to USD 61.41 billion by 2035 (CAGR 7.6%). A secondary industry source cites a similar CAGR (~7.2%), supporting a mid-to-high single-digit growth outlook driven by rising e‑commerce, digital buyer research, and comparison-tool adoption.
Vendor marketing and demand generation
Primary inputs are recent market reports for the demand generation software category, which serve as a close proxy for vendor marketing and demand-generation services. 360iResearch estimates the demand generation software market at roughly USD 7.6B (2026) with a ~9.8% CAGR to 2032; BusinessResearchInsights estimates ~USD 6.6B (2026) with ~11.3% CAGR to 2035. Given those software figures and overlap with services/programs, a conservative current market-size estimate for vendor marketing and demand-generation offerings is ~USD 7.0B, with growth potential around a 9.8% CAGR.
Developer API and data integrations
Estimates synthesized from multiple adjacent market reports in the provided search results (cloud API, API management, API marketplaces, and data integration). Source values range widely (cloud API reports from ~US$2.15B–US$64.8B depending on scope; API management and data-integration reports show mid-single-digit to low-double-digit billions). Because “developer APIs and data integrations” is a focused subset (developer portals, connectors, integration support, marketplace data access), the estimate uses a conservative aggregation and overlap-adjusted midpoint of the cited markets to reflect the segment’s addressable revenue (~USD 20–25B) and a blended growth outlook (mid-teens CAGR) driven by API-first adoption, API management and integration demand, and rising real-time data use cases.
- Global cloud API market size was valued at USD 64.78 billion in 2025; CAGR 31.73% (2025–2034).
- Cloud API market valued at US$2,151.6 million in 2026; expected to reach US$7,749.3 million by 2033; CAGR 20.1%.

- Data integration market valued at USD 13.28 billion in 2023; expected to reach USD 37.78 billion by 2032; CAGR 12.38%.
