G2 vs Capterra: Which B2B Software Review Site Is Worth Your Time?
G2 and Capterra are the two dominant B2B software review platforms, but they have different audiences, ranking mechanics, and buyer journeys. Here is how to choose where to focus your review-building efforts.
For B2B SaaS founders, G2 and Capterra often feel interchangeable — both collect verified reviews, both show up in buyer research, and both require significant effort to build a credible presence. But the differences matter when you are deciding where to concentrate early resources.
What is G2?
G2 (formerly G2 Crowd) was founded in 2012 and hosts over 2 million verified user reviews across 1,500+ software categories. Its signature product is the G2 Grid — quarterly reports that rank products on a Satisfaction vs. Market Presence matrix, placing companies into quadrants like "Leader," "Momentum Leader," "High Performer," and "Niche." These grid reports are heavily used by buyers doing competitive research and are frequently cited in sales conversations. G2 gets approximately 7 million monthly visitors.
What is Capterra?
Capterra was founded in 1999 — making it one of the oldest software review sites — and is now part of Gartner Digital Markets alongside Software Advice and GetApp. It focuses on small and medium businesses researching software purchases across 1,100+ categories. Capterra gets around 4 million monthly visitors and is known for its strong presence in Google search results for software comparison queries. Unlike G2, Capterra has a larger pay-per-click advertising component, meaning vendors who advertise get more prominent placement in category listings.

When to prioritize G2
- You are selling to mid-market or enterprise buyers who use G2 Grid reports in their vendor evaluation process.
- You want grid badges — "High Performer" or "Leader" — to use in marketing collateral and sales decks.
- You are in a competitive category where buyers actively compare multiple vendors on a matrix.
- Your sales reps want to share third-party validation during deals.
- You have enough satisfied customers to cross the review threshold for grid placement (typically 10+ reviews).
When to prioritize Capterra
- Your primary buyers are small business owners searching Google for software comparisons.
- You want organic traffic from comparison-intent queries like "best [category] software."
- Your product fits a well-defined SMB category that Capterra covers thoroughly.
- You have budget to test paid placement alongside organic review-building.
- You want exposure to Gartner's broader network, which includes GetApp and Software Advice.
The honest answer: you likely need both
Most B2B SaaS founders building a review presence end up on both platforms, because buyers check multiple sources. The strategic question is which one to build first and where to concentrate review-gathering efforts. G2 is typically the better starting point if you are targeting enterprise buyers or want grid reports for sales. Capterra earns priority if you are SMB-focused and want Google presence quickly. In either case, getting your first 10 verified reviews on both platforms changes your buyer-facing story significantly.
