G2 Review: Full 2026 Breakdown

G2 is the default starting point for B2B software buying decisions. With over 6 million verified reviews across its ecosystem and more than 200 million annual buyers researching products since its acquisition of Capterra, Software Advice, and GetApp from Gartner in January 2026, it operates as both a marketplace where buyers discover software and a data platform where vendors identify those buyers.

To write this G2 review, we analyzed the platform in depth. It's a good fit if:

• You're a B2B software vendor building credibility through verified peer reviews

• You want to see which companies are researching your product category

• You need marketing content (badges, reports, Grid placements) backed by third-party validation

• Your buyers already use G2 during software evaluation

• You want to position your product for AI-driven software recommendations

• You need vendor-side competitive intelligence on category switching trends and pricing benchmarks

However, G2 might not be the best choice if:

• You need verified contact data (direct dials, business emails) for the buyers showing intent

• You require intent signals from beyond a single review platform

• You want to act on buyer signals with built-in outreach and engagement tools

• You need company firmographics, technographics, and org charts alongside intent data

• You're looking for a platform that combines intelligence and execution in one place

In that case, consider ZoomInfo: an all-in-one AI GTM Platform that pairs B2B data (500M contacts, 100M companies, 135M+ verified phone numbers, 200M+ verified business email addresses) with a GTM Context Graph that combines intent signals, CRM records, conversation intelligence, and behavioral data into a single intelligence layer.

Where G2 tells you which companies are researching software, ZoomInfo tells you who to contact, why they're in-market, and what to say, then gives you the tools to act on it.

We've included a detailed look at ZoomInfo later in this G2 review, as the platform that picks up where G2's intent signals leave off. If you're ready to see how intelligence and execution work together, you can try ZoomInfo free.

What is G2?

G2 is a B2B software marketplace and go-to-market intelligence platform founded in 2012 as G2 Crowd, then rebranded to G2 in 2019.

Co-founded by Godard Abel, Tim Handorf, and Mike Wheeler, the platform was built on a simple premise: software buying decisions should come from verified user reviews, not analyst briefings or vendor marketing.

The platform serves two audiences. For software buyers, G2 is a research destination for reading peer reviews, comparing products, and building shortlists. For software vendors, G2 offers a suite of products spanning Profiles, Reviews, Content, Buyer Intent, Market Intelligence, AI Custom Research, and the newly launched Competitive Pulse.

With the January 2026 Capterra/Software Advice/GetApp acquisition, G2's combined ecosystem now reaches over 200 million annual software buyers and nearly 6 million verified reviews, making it the largest software discovery network by reach.

The ideal G2 vendor customer is a B2B software company with a dedicated marketing or revenue operations function, typically $5M or more in ARR, that invests in demand generation and account-based marketing.

G2 Pros and Cons

G2 Review: How It Works and Key Features

G2 Profiles and Reviews: Build credibility through verified peer validation on the largest B2B review marketplace.

A G2 Profile is a vendor-managed product listing that puts a software company in front of more than 90 million buyers a year on G2's own marketplace, with the broader ecosystem now reaching 200 million buyers annually. Vendors can claim a free profile, then fill it with product information, media, screenshots, demo videos, and pricing details through the my.G2 dashboard.

The profile's value comes mostly from the reviews attached to it. G2's review collection tools include email campaigns with gift card incentives, in-app prompts through integrations with Pendo, Delighted, Medallia, and Sendoso, AI-assisted drafting from customer call transcripts, and video reviews.

Every review goes through human moderation before publication and captures 42 structured data points per submission. G2 also added Verified on LinkedIn to its review moderation (March 2026), producing 100,000+ reviews from LinkedIn-verified buyers and a 40% drop in review rejection rates.

Reviews feed directly into G2's Grid ranking algorithm, which scores products on Satisfaction and Market Presence. Profile completeness and review recency influence category rankings, creating a compounding effect: more reviews improve ranking, which drives more buyer traffic, which generates more intent signals.

On the marketing side, G2 provides embeddable widgets (Grid widgets, Star Rating widgets, Testimonials carousels), downloadable badges (SVG and PNG formats), and a Report Library for competitive comparison reports. The Star Rating widget can inject Product Review schema markup automatically for Google rich snippets.

Buyer Intent Data: Identify companies actively researching your product category on G2.

G2 Buyer Intent captures behavioral signals when software buyers research products on the G2 marketplace. When a visitor from an identifiable organization views a product profile, checks a pricing page, reads an alternatives page, or compares two products, G2 records that activity as a Buyer Intent signal tied to the buyer's organization.

G2 tracks nine signal types: Profile, Pricing, Alternatives, Category, Compare, Sponsored Content, Licensed Content, Reference Page, and Competitive (activity on a competitor's pages). Each signal includes the specific page visited, the buyer organization's name and domain, visitor geolocation, and company firmographics.

Two scoring dimensions help prioritize accounts. Buying Stage (Awareness, Consideration, or Decision) estimates where the buyer sits in their evaluation. Activity Level (Low, Medium, or High) measures behavioral intensity, factoring in time spent per page and total pages visited.

The data integrates with major CRM and ABM platforms including Salesforce, HubSpot, 6sense, Demandbase, ZoomInfo, Salesloft, Outreach, Gong, LinkedIn Sales Navigator, Slack, and Snowflake. Vendors can filter signals by date range, target accounts, firmographics, region, signal type, and competitor products through the my.G2 dashboard.

Market Intelligence: Monitor competitive positioning and switching trends with live data from G2's review corpus.

G2 Market Intelligence turns G2's review database and buyer behavior signals into a continuously updated competitive intelligence hub, available on the Enterprise plan. It draws on over 6 million verified reviews with 40+ data points per review.

The platform organizes intelligence into discrete modules: a Dashboard summary, Satisfaction benchmarking, Win/Loss switching analysis, Pricing and Contracting intelligence, Traffic Analytics, and a Category Overview with AI-generated insights. The Win/Loss module stands out: it shows which products customers are switching to and from, drawn from reviewer-stated behavior. The Pricing and Contracting module reveals competitor pricing sentiment, discount patterns, and contract structures.

Competitive Pulse: Unified deal protection combining CRM data, buyer intent, and competitive research signals.

Announced in March 2026, Competitive Pulse is G2's most material product expansion. It combines a customer's CRM opportunity data with G2 Buyer Intent signals and competitive research behavior to flag at-risk deals.

Key capabilities include Churn Threats (flagging when existing customers show increased engagement with competitors on G2), AEO Traffic insights (answer engine optimization analytics measuring engagement from AI-generated answers), expanded Buyer Intent signals across G2's marketplace, and spend and contract intelligence derived from $100B+ in SaaS purchasing agreements as a Data Solutions add-on.

For marketing and RevOps teams running ABM programs, Competitive Pulse brings G2's intelligence closer to the deal-protection workflows that previously required stitching together separate tools.

G2 MCP Server: Connecting AI assistants to G2 buyer signals and review data.

Also launched in March 2026, the G2 MCP server (Model Context Protocol) connects AI assistants, starting with Claude from Anthropic, to G2 reviews, buyer signals, research behavior, and competitive insights. G2 positions this as its "trust layer" for the AI Answer Economy: as buyers increasingly ask AI assistants for software recommendations, verified G2 review signals become a source of credibility in AI-generated answers.

The G2 MCP server is scoped to G2's own review and buyer-intent dataset. This is worth noting for teams evaluating it alongside platform-level MCP access: ZoomInfo's MCP server exposes the full GTM Context Graph, including contact data, intent signals, CRM overlays, and conversation intelligence.

AI Custom Research: Commission custom buyer-insight studies combining AI interviews with G2's data.

G2 AI Custom Research delivers custom qualitative research faster and cheaper than traditional methods, built on G2's acquisition of unSurvey. The service uses AI voice agents to conduct adaptive interviews with respondents sourced from G2's verified buyer community.

The system can run 100+ daily interviews simultaneously, each capturing 20+ minutes of conversation with real-time follow-up questions. G2 claims 5x faster delivery than traditional research, 70% cost reduction, and 30% higher response rates. This product is sold as a separate engagement and is most relevant to vendors needing custom messaging research, win/loss analysis, or category positioning insights.

What Users Say About G2

G2 as a vendor intelligence platform is used by marketing and RevOps teams at mid-market and enterprise B2B software companies. Based on user feedback aggregated across review platforms and G2's own integration pages:

Users consistently praise G2's first-party verified intent signal quality. The Compare signal, which identifies the specific competitors a buyer benchmarked you against on G2's compare pages, is frequently cited as the most distinctive feature. The G2 Buyer Intent and ZoomInfo integration averages 4.5 out of 5 stars across 9,084 reviews on G2's own partner hub, reflecting how commonly the two platforms are used together.

The most common user critiques track closely with the structural limitations covered in the section below: intent data bounded to a single platform, no contact resolution layer, and pricing escalation that catches teams off-guard. One recurring theme from enterprise teams: G2 intent drives account prioritization well but requires a separate data layer (most commonly ZoomInfo) to convert those account signals into actual outreach. The customer story from impact.com illustrates the upside: their team cut cost-per-lead from $120 to $53 (a 56% drop) using G2 Buyer Intent focused ABM targeting, showing the platform's ROI potential when paired with an activation layer.

Teams without a dedicated customer marketing function to run review campaigns consistently struggle to maintain G2 Grid ranking positions, since the algorithm weights review recency alongside volume.

Where G2 Falls Short

G2 excels as a review marketplace and a source of in-platform buyer signals, but several limitations appear for teams that need to move from intelligence to action.

Intent Data Is Limited to G2's Own Platform.

G2's Buyer Intent captures only activity that happens on G2. Buyers researching through analyst calls, vendor conversations, peer recommendations, or competing platforms generate no signal. For niche verticals with limited G2 traffic, intent signal volume may be too thin to drive a consistent ABM program.

No Contact Data Behind the Intent.

G2 identifies companies, not people. When a signal shows that "Acme Corp viewed your competitor's pricing page," G2 does not provide the buyer's name, email, or phone number. Vendors must add a separate data provider to convert account-level signals into outreach, adding cost and friction. G2 acknowledges this directly: the ZoomInfo integration on the G2 partner hub exists specifically to close this gap, surfacing 50 free ZoomInfo Suggested Contacts per user per month for teams using the integration.

Pricing Is Opaque and Escalates Quickly.

G2 does not publish prices for Professional or Enterprise tiers. Contracts are negotiation-dependent, with wide variation. The Starter plan doubles in price after year one (from $299/month to $599/month). Buyer Intent, Market Intelligence, AI Custom Research, and managed services are all separate add-ons with no public pricing. Auto-renewal clauses with 30-day notice windows and no stated cap on renewal price increases add further unpredictability.

Review Generation Demands Continuous Effort.

Maintaining a competitive G2 profile is not a one-time investment. G2's algorithms factor review recency and volume into Grid rankings, so vendors must run ongoing review campaigns to hold position. Teams without a dedicated customer marketing function often fall behind on review velocity. G2 Review Managed Services can help, but at additional cost.

No Built-In Execution Layer.

G2 identifies buyer interest but provides no tools to act on it. There is no outreach automation, no email sequencing, no dialer, and no sales engagement capability. Vendors must export signals to separate platforms for every downstream action, which slows response time.

Coverage Drops Outside Core Tech Categories.

G2's review and intent coverage is concentrated in B2B SaaS (marketing tech, sales tech, HR tech, DevOps). Vendors in healthcare IT, legal tech, construction tech, or other specialized verticals find thinner category coverage and fewer reviewers, which limits both social proof and intent signal usefulness.

These limitations follow naturally from G2's design as a marketplace. But for teams that need both intelligence and execution, the gap between knowing an account is in-market and reaching the right person with the right message is where a platform like ZoomInfo fits.

Top G2 Alternative for Unified Intelligence and Execution: ZoomInfo

ZoomInfo addresses G2's core limitation: the gap between knowing a company is researching and acting on that knowledge. Where G2 captures buyer signals within its marketplace, ZoomInfo combines B2B data, an intelligence layer that explains why deals move, and access methods that deliver that intelligence to any tool or workflow. ZoomInfo is an all-in-one AI GTM Platform, not just a data provider.

Comprehensive B2B Data: ZoomInfo provides the verified contact and company data that turns account-level signals into outreach.

G2 tells you a company is researching software. ZoomInfo tells you who at that company to contact and how to reach them.

ZoomInfo's data platform covers 500M contacts, 100M companies, 135M+ verified phone numbers, 120M direct dials, and 200M+ verified business email addresses. This data goes through a multi-source verification pipeline backed by 300+ human researchers, achieving up to 95% accuracy on first-party data.

Beyond contact information, ZoomInfo provides 300+ company attributes for segmentation, department org charts with decision-makers, technographic profiles covering 30,000+ technologies across 30+ million companies, and parent-child company hierarchies.

On the intent side, ZoomInfo Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings sourced monthly, capturing research behavior across the open web rather than one platform. Guided Intent, exclusive to ZoomInfo, identifies topics historically correlated with deal success rather than requiring manual topic selection.

In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close."

GTM Context Graph: ZoomInfo's intelligence layer captures not just what happened in a deal, but why.

G2's Market Intelligence shows competitor positioning and switching trends based on review data. ZoomInfo's GTM Context Graph goes further by combining ZoomInfo's B2B data with your CRM records, conversation transcripts, email interactions, and behavioral signals into a graph that processes 1.5B+ data points daily.

A CRM records that a deal moved stages. G2 Market Intelligence shows that a competitor is gaining review momentum. The GTM Context Graph connects both to the conversation where the CFO raised ROI concerns, the intent spike showing the account is researching alternatives, and the hiring patterns suggesting an upcoming technology decision. It captures the reasoning behind outcomes, not just the events.

This intelligence powers every downstream action: follow-up emails address the specific concern a stakeholder raised, GTM plays target accounts matching your actual win patterns, and forecasts weight deals by buying evidence rather than stage labels.

ZoomInfo holds a leadership position in the Forrester Wave for B2B Intent Data Providers, a category G2 Buyer Intent competes in but has not claimed analyst recognition in. For marketing and demand gen leaders whose CMOs read Gartner and Forrester reports, this is a material defensibility difference.

Seismic, a leading sales enablement platform, attributed 39% of active pipeline to ZoomInfo-influenced opportunities. Toby Carrington, Chief Business Officer, stated: "That combination of our internal CRM data, external signals, and AI that's given all that context has helped us craft very specific account- and persona-based messages." (Seismic Case Study)

Smartsheet's demand gen team, using ZoomInfo's FormComplete and intent data for ABM, reported an 84% increase in MQLs sent to sales, a 26% increase in opportunity rate, and a 59% increase in win rate. (Smartsheet Case Study)

Universal Access: Use ZoomInfo's intelligence in any tool, any workflow, any AI agent.

G2 integrates with CRM and ABM platforms to push intent signals downstream. ZoomInfo delivers its intelligence through three channels, so where you work never limits the intelligence available.

GTM Workspace gives sellers a single place where prioritized accounts, AI-drafted outreach, and deal execution come together. AI agents handle account research, follow-ups, signal monitoring, and CRM updates. Thomson Reuters increased closed-won deals by 40% and reached 115% average monthly quota attainment using GTM Workspace.

GTM Studio gives marketers, RevOps, and GTM engineers a builder environment where audience definition, campaign orchestration, and pipeline measurement happen in natural language. Expansion plays that used to take three weeks now launch in 30 minutes.

For teams building beyond ZoomInfo's products, APIs and MCP expose the same intelligence to any custom agent, internal tool, or partner platform. API access is included in all relevant plans.

Jerry Wilson, Senior Marketing Intelligence Analyst at BDO Canada, stated: "The plug-and-play aspect of the API means I can integrate it very easily into any process and get information at a moment's notice." The team cut time spent on internal data dashboard updates by 87%. (BDO Canada Case Study)

Pricing: Free to start with consumption credits based on usage.

ZoomInfo pricing is free to start with consumption credits based on usage. A permanent free tier (ZoomInfo Lite) is available with access to ZoomInfo's B2B database, 10 monthly export credits, individual and company searches, a Chrome extension, and WebSights Lite for website visitor identification. A separate 7-day free trial gives broader access to core platform features.

G2 or ZoomInfo: Comparison Summary

Final Verdict

The choice between G2 and ZoomInfo depends on what problem you're solving.

Choose G2 if you need to build credibility in the B2B software marketplace through verified peer reviews, earn Grid placements and badges that strengthen your marketing, and capture intent signals from buyers evaluating software on the platform. G2 is most valuable when your buyers already use it as part of their research process and when your marketing team can activate account-level intent signals through existing CRM and ABM workflows. The March 2026 Competitive Pulse launch makes G2 a more serious deal-intelligence option for enterprise teams. For software vendors investing in brand presence and third-party validation, G2 remains the leading marketplace.

Choose ZoomInfo if you need the full picture: not just which companies are researching, but who to contact, why they're in-market, and what to say. ZoomInfo closes the gap between intelligence and action by combining B2B data with a GTM Context Graph that reasons across your CRM, conversations, and market signals, then delivers that intelligence through native execution tools and open APIs.

For teams that need to move from signal to outreach without stitching together multiple platforms, ZoomInfo provides the foundation.

Get started with ZoomInfo here.

Many teams use both: G2 for marketplace presence and review-derived credibility, and ZoomInfo for the contact data, broader intent coverage, and execution infrastructure that turns signals into revenue. G2 integrates directly with ZoomInfo, making the two platforms complementary rather than exclusive for organizations that can invest in both.

G2 FAQ

What does G2 cost for software vendors?

G2 offers a permanent free tier for basic profile management and review collection. The Starter plan costs $299/month in year one, but doubles to $599/month in year two. Professional and Enterprise tiers are not publicly priced and require a sales conversation.

Buyer Intent, Market Intelligence, Competitive Pulse, AI Custom Research, and managed services are separate add-ons with no published pricing. ZoomInfo is free to start with consumption credits based on usage, with a permanent free tier (ZoomInfo Lite) and a 7-day free trial.

How does G2 Buyer Intent data work?

G2 captures behavioral signals when buyers from identifiable organizations interact with product profiles, pricing pages, competitor comparisons, and category pages on the G2 marketplace. Signals are scored on two dimensions: Buying Stage (Awareness, Consideration, Decision) and Activity Level (Low, Medium, High). The data integrates with Salesforce, HubSpot, 6sense, Demandbase, ZoomInfo, and other platforms.

The key limitation: signals only capture activity on G2 itself, not across the broader web.

Does G2 provide contact information for buyers showing intent?

No. G2 identifies organizations, not individuals. When intent data shows a company researching your product category, G2 provides the company name, domain, firmographics, and the specific pages visited, but not the name, email, or phone number of the person doing the research.

The G2 and ZoomInfo integration directly addresses this: it surfaces ZoomInfo Suggested Contacts inside my.G2 for accounts triggering G2 intent signals, giving teams 50 free ZoomInfo contacts per user per month for 6 months. For ongoing contact resolution at scale, a ZoomInfo subscription closes the gap fully.

How many reviews does a vendor need on G2 to be competitive?

G2 does not publish a minimum review threshold for Grid placement, but its algorithms weight both review volume and recency. The "Users Love Us" badge requires at least 20 reviews with an average rating of 4.0 stars or higher. A product needs a minimum of 10 responses to appear in a Compare Report. Maintaining competitive positioning requires ongoing review campaigns, as stale reviews lose weight over time.

What is G2's AI Answer Economy positioning?

G2 claims its reviews are cited more often in AI-generated answers than competing sources. The platform has launched AEO (Answer Engine Optimization) analytics to measure engagement from AI-generated answers and conversational search. The March 2026 Competitive Pulse announcement also includes expanded Buyer Intent signals and an MCP server integration with AI assistants, starting with Claude from Anthropic. The strategy: as buyers increasingly ask AI assistants for software recommendations, a strong G2 review presence becomes a channel for AI-driven discovery.

Does G2 integrate with CRM and sales tools?

Yes. G2 Buyer Intent integrates with Salesforce (G2 CRM Connector on AppExchange), HubSpot, Pipedrive, Salesloft, LinkedIn Sales Navigator, ZoomInfo, 6sense, Demandbase, Marketo, Outreach, Gong, Slack, and Snowflake. The ZoomInfo integration is bidirectional: G2 Buyer Intent data flows into ZoomInfo Sales and ZoomInfo Marketing, and ZoomInfo Suggested Contacts surface inside my.G2. The integration averages 4.5 out of 5 stars across over 9,000 reviews on G2's partner hub.
