Platform Markets and Partner Differentiation: What the Evidence Shows

Vertical depth, not horizontal breadth, drives partner value-capture

Two independent studies quantify the revenue and growth gap between vertically focused partners and those competing across broad service catalogues.

This pattern holds across regions: partners with narrower scope consistently achieve higher attach rates and stronger co-sell outcomes than those maintaining broad service catalogues.

• EY research on technology partner economics (2025) finds that partners in the top quartile of hyperscaler marketplace revenue operate in 2.3 fewer service categories than median partners, confirming that vertical depth outperforms horizontal breadth as a value-capture strategy in platform markets.
• Zinnov's ecosystem partner research (2024) finds a 4.1x revenue growth differential between partners with a defined domain specialisation (industry-vertical or technology-specific) versus those offering generalised cloud services — a gap that has widened year-on-year since 2021.
• ADAPT research on Asia-Pacific technology partner markets finds that enterprise buyers increasingly shortlist only partners with verifiable domain outcomes (named customer case studies in the buyer's sector), reducing the effective market for undifferentiated partners by approximately 35% between 2023 and 2025.
• Gartner's analysis of hyperscaler partner program economics (2025) finds that the top 5% of partners by marketplace revenue capture approximately 40% of total ecosystem revenue — a concentration ratio that has grown consistently, suggesting platform markets are winner-takes-more rather than evenly distributed.

Platform markets are shifting from access to outcomes, squeezing the middle

Hyperscaler platform markets are evolving from access markets (where the value of participation is the customer reach the platform provides) to outcome markets (where the value of participation is determined by verified domain expertise the partner brings). The Gartner concentration ratio suggests that the middle of the partner distribution — firms that are not large enough to compete on breadth and not specialised enough to compete on depth — is being structurally squeezed.

The D3 (Digital Business Platforms) lens identifies this as a platform dynamics outcome: as the platform matures, it layers on services that commoditise what partners previously offered, forcing partners up the specialisation stack or out of the market. Technology providers that have built domain expertise rather than delivery capacity are positioned to capture the specialisation premium the EY and Zinnov data quantifies.

Limitations and Caveats

EY and Zinnov partner research is drawn from partner surveys and marketplace data that may not fully represent smaller or regionally-focused participants. The Gartner concentration ratio reflects marketplace revenue rather than total partner ecosystem revenue — managed services and professional services partnerships are not fully captured in marketplace data. ADAPT Asia-Pacific findings may not generalise to European or North American partner markets.

Implications for Enterprise

The evidence points to two concrete decisions for technology providers competing in hyperscaler ecosystems.

1. Technology providers competing in hyperscaler ecosystems should prioritise verified domain outcomes (named case studies, sector-specific certifications) over breadth of service catalogue — the EY 2.3 category finding suggests that reducing scope improves partner economics.
2. Mid-tier partners facing margin compression should treat specialisation as a platform positioning decision, not a marketing decision — the Zinnov 4.1x differential indicates the revenue impact of domain focus is structural.
3. Enterprise buyers evaluating technology partners should treat hyperscaler tier status as a floor condition rather than a differentiator — the ADAPT shortlisting data suggests buyers have already moved to outcome evidence as the primary evaluation criterion.

Both findings converge on the same structural point: platform economics now reward positioning decisions made well upstream of any individual deal.
