How big is G2’s footprint after the acquisition?
According to G2’s own disclosures, the combined group will host around 6 million verified software reviews and reach more than 200 million software buyers annually across thousands of categories.
Individually, the platforms already commanded significant scale:
- G2 reports over 3 million verified reviews on its platform
- Capterra publicly states it hosts more than 2.5 million reviews across business software categories
- Software Advice and GetApp, both part of Gartner Digital Markets, contribute additional large review inventories, though Gartner does not break out exact figures per site
- G2 accounted for ~23.1% of review-platform citations
- Capterra for ~17.8%
- Software Advice for ~12.8%
(GetApp was included within the same Gartner Digital Markets cluster and not listed separately)
Taken together, these figures imply that platforms now owned by G2 represent approximately 53–54% of global software-review visibility in this dataset. Analysts estimate that including GetApp’s additional reach lifts that figure to roughly 55–58% of review and discovery influence, depending on methodology.
Is that a monopoly?
Why the industry is uneasy
Vendors and analysts point to several risks:
- Pricing power: fewer alternative platforms may reduce vendors’ ability to diversify demand generation
- Ranking influence: consolidated control over taxonomies, badges, and visibility logic could shape outcomes across categories
- AI amplification: as AI search tools rely on dominant review sources, concentration at the data level may translate into disproportionate downstream influence
The bottom line
G2 is not a monopoly in the legal sense. But by combining G2, Capterra, Software Advice, and GetApp, the company has moved into clear gatekeeper territory, with control over more than half of global software-review influence by several independent measures. That level of concentration explains why the software industry, and potentially regulators are beginning to ask whether G2’s growing power has gone too far.
