This analyst relations firm directory covers ten research and advisory firms that B2B technology vendors brief and get evaluated by: Gartner, Forrester, IDC, HFS Research, ISG, S&P Global Market Intelligence (formerly 451 Research), Omdia, Constellation Research, Everest Group, and Moor Insights & Strategy. Six firms carry a scored 2026 EPR Analyst Visibility Index rating, while four are interim profiles ahead of the Index's 2027 expansion.
Which Analyst Firms Carry an EPR Analyst Visibility Index Rating?
Six firms carry a scored rating in the 2026 EPR Analyst Visibility Index. The Index measures how often ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews cite each firm across a locked 120-prompt set.
Which Firms Have Interim Profiles Before the 2027 Index Expansion?
Four firms carry an interim, qualitative profile because formal EPR Analyst Visibility Index scoring for these firms begins with the 2027 edition. Their profiles are based on citation testing rather than the full five-factor scoring model.
What Separates Institutional Firms From Named-Voice Firms?
Institutional firms, such as Gartner, Forrester, IDC, ISG, and Omdia, publish research under the firm's brand. This produces consistent institutional citation share but results in weaker retrieval for queries asking for a specific person's opinion.
Named-voice firms, such as Constellation Research and Moor Insights & Strategy, publish under individual analysts. For example, Ray Wang and Holger Mueller lead at Constellation, while Patrick Moorhead and his colleagues lead at Moor Insights. This model results in strong retrieval on named-analyst queries and weaker retrieval outside each analyst's specific coverage area.
Why it works: AI engines retrieve structured, attributable claims more reliably than unattributed institutional prose. A named analyst's on-the-record, dated quote in Forbes or on CNBC is a structured claim. Similarly, a Magic Quadrant placement is a structured claim. Firms that publish only paywalled institutional reports must route their citation share through secondary press coverage. Firms built around named, publicly quotable analysts get cited more directly and faster after each research cycle, according to EPR's 2026 Analyst Visibility Index findings.
How Should a Vendor Decide Which Firms to Brief First?
A vendor should brief Gartner, Forrester, and IDC first if the goal is a Magic Quadrant, Wave, or MarketScape placement. A broad enterprise buying committee will see these placements.
These three firms hold 87 percent of all analyst citations across the five major AI engines combined. Vendors should brief ISG, HFS Research, or Everest Group first if the category is sourcing, managed services, or business process outsourcing. In these categories, those three firms outperform the Big Three.
A vendor selling AI infrastructure or semiconductors should add Moor Insights & Strategy to the briefing list. This firm provides fast, quotable, single-analyst commentary that a Gartner or Forrester report cycle cannot match in speed.

Which analyst firm has the highest AI citation share?
Gartner has the highest AI citation share, with a 2026 EPR Analyst Visibility Index score of 94.2. This represents roughly 94 percent citation share across the five major AI engines on analyst-relevant buyer queries.
What is the difference between an institutional analyst firm and a named-voice analyst firm?
An institutional firm, like Gartner or Forrester, publishes under the firm's brand and gets cited as an organization. A named-voice firm, like Constellation Research or Moor Insights & Strategy, publishes under individual analysts who are quoted and cited by name.
When does the EPR Analyst Visibility Index add Omdia, Constellation, Everest Group, and Moor Insights & Strategy?
Formal scoring for Omdia, Constellation, Everest Group, and Moor Insights & Strategy begins with the 2027 edition of the Index. Their current profiles are qualitative, based on citation testing rather than the full five-factor scoring model applied to the six 2026 firms.
