G2 Evaluation & Top 3 G2 Competitors in 2024

B2B technology review platforms are important because they provide firms with valuable information and insights regarding technologies that make their businesses more efficient. These platforms often provide this information to help businesses make informed decisions about technology investments: 

  • user reviews
  • comparisons of different products and services

Buyers are eagerly looking for unbiased and insightful reviews for purchasing a product, and vendors are looking for more online reviews for awareness:

  • 92% of B2B tech buyers are depending on trusted reviews for their purchases.
  • Five product reviews increase the conversion rate by 270%.

G2 is such a technology review platform aiming to help both buyers and vendors. However, there are some shortcomings of G2 on closer inspection such as potential sources of bias in reviews and the difficulty of gaining product insights since those insights are scattered across thousands of reviews.

In this article, we will review the performance of G2 and compare it against the top 3 G2 competitors.

G2 review

G2 is a B2B software marketplace founded in 2012, providing peer-to-peer software and technology online reviews. According to their statement, more than 60% of Forbes Cloud 100 are G2 customers.1

G2 gathers user reviews and ratings for various software products and services and then uses that data to create rankings and reports. These rankings and reports are intended to help businesses and individuals make better product decisions when choosing the right software and technology. 

G2 uses the reviews and market presence data to create scores for satisfaction and market presence and then use these scores to place products into one of four categories on the G2 Crowd Grid:

  • Leaders
  • High Performers
  • Contenders
  • Niche.

G2 also provides a marketplace for vendors to list and promote their products.

Business size of users

  • Most reviewers of G2 in other review platforms are from mid-market companies.

User ratings

  • Trustpilot: 4.8/5


G2 has a 4 different pricing plans with different features:

  • Free
  • Essential
  • Pro
  • Power


  • G2 claims to use an algorithm to detect and remove fake user reviews, specifically those written by employees of the company being reviewed, or employees of the company’s competitors.
  • G2 claims that its community manually reviews and approves comments to prevent spam and irrelevant feedback.
  • G2 also asks for screenshots as proof of usage from the reviewer to ensure authenticity.


  • G2’s model reduces reviews to two numbers; the total number of reviews and the rating. For more information, a user needs to read through thousands of reviews which is not practical. This model pushes buyers to focus on a few providers and miss out on those that may offer a better solution for their specific business thanks to superior pricing, industry-specific focus etc.
  • Though they are the largest review platform regarding overall web traffic, they are not the market leader in all domains. For our analysis of market leadership with SEMrush analytics, you can check our article on best software reviews
  • Some reviewers state that the platform is not accepting their reviews despite satisfying the required features.
  • Some reviewers state that the platform is biased since it rejects some negative reviews of their advertisers.
  • Some technology related topics are not comprehensively covered by the company

Top 3 competitors of G2

Below, we listed the best alternatives according to the alphabetical order. However, we can be biased in this domain as a competitor of G2.


AIMultiple is the emerging technology industry analyst that assists companies in researching, selecting, and evaluating new technology solutions through the use of transparent metrics. 

AIMultiple addresses fundamental problems of review platforms with its approach:

  • Most tech users never write reviews. AIMultiple leverages data beyond reviews including online popularity of technology solutions, their number of employees, case studies etc.
  • Buyers do not have enough time to read reviews. Even if they had the time, they would be utterly confused since there is an abundance of superficial reviews that reflect the personal biases and unique working conditions of numerous users. AIMultiple summarizes review findings in product pages to highlight key aspects of solutions.
  • Reviews are not confined to a single platform. G2 users miss out on learning about testimonials, case studies and reviews on other review platforms like TrustRadius, PeerSpot, Gartner Peer Insights etc. AIMultiple aggregates all of these sources of information.

User Ratings

  • Trustpilot: 4.2/5
