One Company Now Owns the Review Record for 96% of B2B Software

One company now owns the review record for 96% of B2B software. We measured it across 4,335,232 aggregated reviews covering 10,248 products.

In January 2026, G2 announced it would acquire Capterra, Software Advice and GetApp from Gartner, closing on 5 February for roughly $110 million. Before that deal, G2 and the Gartner properties were each other's main competitor. After it, they are the same company.

We aggregate third-party ratings across our catalog, which means we can measure what that consolidation actually covers rather than estimate it.

What one owner now covers

Toolradar data, 4,335,232 reviews aggregated across 10,248 published products, August 2026.

G2 and Capterra together hold 92% of every review we aggregate. Both are now owned by G2.

The dependency is deeper than the share suggests

A market share figure understates this, because what matters to a vendor is not the share of reviews but whether an alternative exists for their specific product. We can measure that too.

Of the 6,499 products in our catalog that carry any third-party reviews at all:

• 3,624 (56%) appear on both G2 and Capterra
• 1,834 (28%) appear on G2 and not Capterra
• 774 (12%) appear on Capterra and not G2
• 267 (4%) appear on neither

So 6,232 products, 96% of everything reviewed, now depend on a single owner for their public review record. Only 267 products have a third-party reputation that sits entirely outside it, and the average product we track carries reviews on 1.73 sources, so most have no second opinion to fall back on.

Why the remaining alternatives are not alternatives

The obvious response is that other platforms exist. They do, at a scale that does not substitute.

TrustRadius is named in nearly every ranking of review sites as a peer of G2 and Capterra. It covers 100 products in our catalog against G2's 5,429, and holds 463 times fewer reviews. It is a credible enterprise source, not a general-purpose one.

Trustpilot has real depth, averaging 699 reviews per product, the highest of any source here. But it covers only 250 of our products, and it collects from consumers rather than verified business buyers, which is a different signal answering a different question.

SourceForge is the inverse: broad at 994 products, shallow at 167 reviews each.

None of the three is a place a B2B vendor can move to and expect comparable reach.

What this changes for software buyers

Cross-checking two sources may no longer mean what it used to. Comparing a product's G2 rating against its Capterra rating was the standard sanity check. Both properties now answer to one owner, and while the review corpora remain separate today, the incentive structure behind them is no longer independent.

The commercial model deserves attention it did not get before. These platforms sell placement, buyer-intent data and leads to the same vendors they rate. That tension existed before the acquisition and was tolerable because a competitor could expose it. Consolidation removes the competitor.

267 products, 4% of those reviewed, are the actual control group. They carry third-party reputation entirely outside the G2 family, and they are worth more attention than their number suggests: they are the only remaining sample where the review record and the leads business have no common owner.

Methodology

We aggregate publicly published review counts and ratings from third-party platforms across the 10,248 products in our catalog, recording each source separately rather than blending them into a single score. Figures above are the state of that aggregation in August 2026.

Counts are of reviews each platform publicly reports, not reviews we have independently verified. Coverage reflects products in the Toolradar catalog, which skews toward B2B software with an active web presence, so consumer and on-premise-only categories are underrepresented. Case variants of the same platform name are folded together.

We have no commercial relationship with any platform named here.

What a buyer should do differently now

The consolidation changes three habits worth naming.

Cross-checking two sources is no longer two sources. Comparing a product's G2 rating against its Capterra rating was the standard sanity check. Both properties now answer to one owner. The review corpora remain separate today, but the incentive structure behind them is no longer independent, so treat agreement between them as weaker evidence than it was.

The 4% outside the family is the real control group. Of the 6,499 reviewed products in our catalog, only 267 carry third-party reputation entirely outside G2 and Capterra. Those are the only products whose review record and lead-generation business have no common owner, which makes them disproportionately useful as a reference point when a rating looks too clean.

Weight recency and specificity over stars. A single detailed review describing a real workflow is now worth more than an aggregate score, because the aggregate sits inside a system that sells placement to the vendors it rates. The star number was always soft; consolidation makes it softer.
