Analyst Relations Firm Directory: Gartner to Moor Insights
This directory covers ten analyst 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. It lists the research firms that publish analyst reports. It does not list analyst relations agencies, the consultancies a vendor hires to run its analyst program. Each firm below is profiled by what it covers, how it publishes research, and which vendors typically brief it.

What does "analyst relations firm" mean?
"Analyst relations firm" is used in two ways, and this page covers the first.
An analyst firm is a research and advisory company, such as Gartner or Forrester, whose analysts publish reports that vendors try to influence and appear in. The ten firms below are analyst firms.
An analyst relations agency or consultancy is a services company that a vendor hires to run or support its analyst relations program: planning briefings, managing inquiries, and preparing for evaluations such as a Magic Quadrant.
If you are searching for an agency to hire, start with the 2026 Analyst Relations Playbook, which explains what an AR program does, who runs it inside companies, and what EPR estimates it costs by company stage. EPR does not rank analyst relations agencies on this page.
What do the ten analyst firms cover?
The ten firms split roughly into broad enterprise-technology advisory firms and category-specialist firms. The table summarizes each firm's core focus and links to its profile.

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 and not under an individual analyst's byline. Reports, Magic Quadrants, Waves, and MarketScapes carry the firm name as the primary credited source.
Named-voice firms, such as Constellation Research and Moor Insights & Strategy, publish under individual analysts. Ray Wang and Holger Mueller are the best-known names at Constellation, and Patrick Moorhead leads at Moor Insights. Vendors briefing these firms are often briefing a specific analyst's beat, not the institution as a whole.
The two models call for different briefing strategies. Briefing an institutional firm means aligning with a fixed research cycle and methodology, such as the annual Magic Quadrant refresh. Briefing a named-voice analyst means building a direct relationship with that person's coverage area, since commentary and press availability move faster than an institutional report cycle. EPR has not re-verified current analyst names, so check each firm's own site before citing a person.
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, since these reach the broadest enterprise buying committees.
A vendor in sourcing, managed services, or business process outsourcing should brief ISG, HFS Research, or Everest Group first, where those firms carry more category-specific weight.
The term has two meanings. An analyst firm, such as Gartner, Forrester, or IDC, is a research company whose analysts publish reports that vendors brief. An analyst relations agency is a services company that vendors hire to run their analyst program. This directory covers the analyst firms.
What does an analyst relations agency do?
An analyst relations agency plans analyst briefings and inquiries, prepares a vendor for evaluations such as the Magic Quadrant or the Forrester Wave, and coordinates the analyst program with PR and marketing. EPR's playbook describes these tasks and estimates program costs by company stage.
How many analyst firms does this directory cover?
The directory covers ten: Gartner, Forrester, IDC, HFS Research, ISG, S&P Global Market Intelligence (451 Research), Omdia, Constellation Research, Everest Group, and Moor Insights & Strategy.
What is the difference between an institutional and a named-voice analyst firm?
An institutional firm, like Gartner or Forrester, publishes research under the firm's brand. A named-voice firm, like Constellation Research or Moor Insights & Strategy, publishes under individual analysts who are quoted and cited by name.
Which analyst firms compete directly with each other?
ISG, HFS Research, and Everest Group compete directly in sourcing, managed services, and business process outsourcing research. Gartner, Forrester, and IDC compete across broad enterprise IT research, each with a different flagship methodology: the Magic Quadrant, the Wave, and the MarketScape.
What methodologies do these firms use to evaluate vendors?
Gartner uses the Magic Quadrant and Hype Cycle, Forrester uses the Wave, IDC uses the MarketScape, and ISG uses Provider Lens. Constellation Research and Moor Insights & Strategy rely mainly on named-analyst commentary. The decision for a vendor is to choose its first three analyst firms by buyer and category, not by brand size, before it hires an agency or builds a program.
