Most B2B buying happens before a prospect ever talks to sales. Research from 6sense suggests 94% of buying groups have already ranked their preferred vendors before first contact. If your team can't see that research activity, you're invisible during the window that matters most.

Intent data platforms solve this by tracking content consumption, keyword searches, review-site visits, and web behavior across thousands of sources — then surfacing the accounts showing unusual spikes in research activity. But the market is crowded, the pricing is opaque, and the differences between vendors aren't always obvious.

This list breaks down the eight platforms worth evaluating in 2026, organized by what each does best. We looked at data sourcing methodology, signal resolution (account vs. contact level), integration depth, activation capabilities, and real-world pricing.

1. Bombora — Best for Third-Party Co-Op Intent Data

Bombora pioneered the B2B intent data category with its cooperative data model. Its Data Co-op collects consent-based signals from 5,000+ premium B2B publisher websites, tracking billions of interactions monthly. When employees at a company consume content at rates above baseline, Bombora flags a "Company Surge" signal across 12,000+ intent topics.

The co-op model is what makes Bombora foundational. Multiple platforms on this list — including 6sense, Demandbase, Cognism, and Apollo — resell or integrate Bombora data under the hood. Forrester named Bombora a Leader in the 2025 Intent Data Providers Wave, and the co-op grew roughly 20% in 2025 with topic coverage up 13%.

Strengths: Widest third-party coverage, consent-based sourcing, weekly Surge scoring (0–100 scale), and integrations with virtually every ABM and CRM platform. If you want a pure intent data feed without being locked into a specific activation stack, Bombora is the default choice.

Weaknesses: Account-level only — you know which company is surging, not which individual. Your team still needs to identify the right contacts within the account. For a deeper look at Bombora's data model and pricing, see our Bombora intent data guide.

Pricing: Starts around $25,000–$30,000/year for the basic Company Surge plan. Most implementations land between $50,000–$100,000 depending on topic count and data volume.

Best for: Mid-market and enterprise teams that want high-quality third-party intent data to feed into their existing sales and marketing stack.

2. 6sense — Best for Predictive AI and ABM Orchestration

6sense is the most feature-rich ABM platform on the market, combining proprietary intent data, predictive AI, and multichannel orchestration. Its Signalverse technology processes over 1 trillion buying signals daily in 40+ languages, supplemented by partnerships with Bombora, TechTarget, TrustRadius, and G2.

6sense has been named a Leader in the Gartner Magic Quadrant for ABM Platforms for five consecutive years, ranking highest for Ability to Execute. The platform doesn't just tell you who's researching — it predicts which accounts are most likely to buy and where they are in the buying journey.

Strengths: Predictive buying stage identification, AI-powered account scoring, multi-source signal aggregation, and built-in ad orchestration. The RevvyAI agents launched in 2025 automate account qualification and outreach recommendations.

Weaknesses: Steep learning curve — building orchestration automations takes significant ramp time. Enterprise pricing puts it out of reach for smaller teams. The platform can overwhelm teams that aren't ready for full ABM maturity.

Pricing: Free tier offers buyer discovery and 50 credits/month. Paid plans typically range from $60,000 to $300,000+/year depending on modules and account universe.

Best for: Enterprise organizations running mature ABM programs that want intent data, predictive scoring, and activation in a single platform.

3. Demandbase — Best for Full-Stack Account-Based Marketing

Demandbase One combines proprietary intent data with advertising, website personalization, and sales intelligence in one platform. It tracks 500+ billion signals monthly across 300,000+ intent keywords and uses identity resolution to tie activity back to specific accounts.

Forrester named Demandbase a Leader in the 2025 Intent Data Wave, highlighting its "highly accurate identity resolution capabilities." Gartner ranked it highest for Completeness of Vision in the 2025 ABM Magic Quadrant.

Strengths: Unified advertising, website personalization, and intent intelligence. Strong identity resolution across multiple signal types. The 2025 design overhaul added predictive surfacing of relevant ICPs and deal-risk accounts.

Weaknesses: Modular pricing escalates fast once you add advertising credits, AI orchestration, and CRM connectors. The initial sticker price can nearly triple by the time you have a functional deployment.

Pricing: Starts around $18,000–$32,000/year for small businesses. Median deployment is roughly $65,000/year. Full enterprise packages reach $100,000–$250,000+.

Best for: Enterprise marketing teams running multi-stakeholder ABM plays that want advertising, website personalization, and intent intelligence unified in one platform.

4. G2 Buyer Intent — Best for Second-Party Review Signals

G2 Buyer Intent captures signals from the world's largest B2B software review platform. When a prospect views your product profile, compares you against competitors, or browses your category page, G2 flags that activity — including company name, visit dates, pages viewed, and visitor count.

What makes G2 intent data special is signal fidelity. The underlying behavior — actively comparing software vendors and reading peer reviews — is unambiguously purchase-related. There's no guessing about whether the account is "in-market." Someone reading reviews of your product category is evaluating solutions. Period.

Strengths: Highest-fidelity intent signal available for SaaS. Buying Stage and Activity Level scoring. Integrations with Salesforce, HubSpot, 6sense, Demandbase, and major sales engagement platforms. Over 12 million buyers visit G2 annually.

Weaknesses: Limited to companies whose categories exist on G2. Uses third-party matching to identify visiting companies, which introduces some accuracy loss. Requires mature ABM workflows to convert signals into pipeline.

Pricing: Buyer Intent is included with G2 Professional and Enterprise packages (starting around $6,000/year for Professional). Standalone intent pricing is custom. Many companies negotiate significant discounts.

Best for: SaaS companies that want to know exactly which prospects are evaluating their category right now.

5. ZoomInfo — Best for Combined Intent + Contact Data

ZoomInfo bundles intent data as part of its broader sales intelligence platform, which includes one of the largest B2B contact databases (300M+ contacts, 100M+ company profiles). The ZoomInfo Copilot AI layer processes real-time intent data alongside contact information to surface outreach recommendations.

Named a Leader in the 2025 Gartner Magic Quadrant for ABM for the second consecutive year, and the only vendor recognized as a Gartner Customers' Choice for ABM in 2025. The primary value is convenience: intent signals alongside verified contacts in a single workflow.

Strengths: Intent data bundled with a massive contact database. Copilot AI automates insight surfacing and outreach suggestions. No need to buy separate tools for contacts and intent.

Weaknesses: User reviews consistently report accuracy issues with ZoomInfo's intent layer specifically — "high-intent" accounts that, when contacted, had no awareness of the flagged topics. The contact database is strong; the intent data is middling compared to dedicated providers.

Pricing: Professional starts around $15,000/year. Advanced: $25,000–$30,000/year. Elite (full Copilot): ~$40,000/year. Intent data ("Streaming Intent") is an add-on priced by keyword volume.

Best for: Teams already using ZoomInfo for contact data that want to layer in intent signals without adding another vendor.

6. Intentsify — Best for Multi-Source Precision Intent

Intentsify earned the highest overall score for Current Offering in the Forrester Wave Q1 2025, receiving the highest possible score across 12 of 21 evaluation criteria. Its "Precision Intent" technology calibrates intent models specifically to each customer's products rather than using generic topic categories.

The platform monitors over a trillion monthly intent signals and aggregates multiple proprietary and third-party sources. Its Orbit identity graph enables buying-group-level attribution — one of the most significant innovations in intent data over the past two years, according to Forrester.

Strengths: Product-calibrated intent models (not just generic topics), buying-group-level attribution, and managed activation services including advertising and content syndication. Particularly strong for teams that lack internal resources for sophisticated targeting campaigns.

Weaknesses: The managed-service model can feel inflexible for organizations that prefer full self-service control. Not ideal for startups or teams with small budgets.

Pricing: Not publicly listed. Combines annual subscriptions with CPM/CPL-based activation fees. Third-party benchmarks suggest median annual spend in the mid-five-figure range.

Best for: Mid-market and enterprise teams that want intent intelligence and managed activation services in one package.

7. TechTarget Priority Engine — Best for Technology Buyer Intent

TechTarget's Priority Engine generates intent data from an extensive network of technology-focused editorial websites. The data is opt-in and contact-level — meaning you get individual contacts, not just account signals. The platform tracks over 1.4 million intent signals from 32 million opt-in B2B professionals.

Named both a Leader and Customer Favorite in the Forrester Wave Q1 2025. If you sell to IT buyers, TechTarget provides the closest you can get to knowing exactly what they're evaluating — because the signal comes from editorial content consumption on TechTarget's own publications.

Strengths: Contact-level resolution (not just account-level), opt-in data with high compliance, deep coverage of IT and technology purchasing signals. Content syndication bundled with intent data.

Weaknesses: Narrow focus. Excellent for technology purchasing signals but minimal coverage for non-tech buying scenarios (HR, finance, operations). The UI has drawn criticism for complexity.

Pricing: Custom, typically $5,000–$15,000/month depending on topic coverage and lead volume.

Best for: Technology vendors selling to IT departments, cybersecurity teams, cloud infrastructure buyers, or enterprise software decision-makers.

8. Warmly — Best for Website Visitor Identification

Warmly is a person-level website visitor identification platform that combines first-party intent with Bombora third-party data and orchestration. The platform identifies up to 65% of companies and 45% of individual contacts visiting your website, using 20+ data providers for cross-validation.

Unlike most intent data platforms that surface account-level signals, Warmly attempts to identify specific individuals browsing your site. It also bundles AI chatbot, live video chat, and email/LinkedIn automation — making it a full activation layer rather than just a data feed.

Strengths: Person-level website identification, free tier for getting started, built-in outreach orchestration, and Bombora integration for third-party context. Strong for teams that want to act on intent signals without a separate ABM platform.

Weaknesses: Person-level identification rates vary significantly by traffic source and visitor behavior. The 45% contact identification claim is a peak number; real-world rates depend on your audience. Newer entrant with less enterprise validation.

Pricing: Free plan identifies up to 500 website visitors/month. Paid plans range from $10,000–$25,000/year depending on features and orchestration capabilities.

Best for: SMBs and mid-market teams wanting person-level website intent identification without the price tag of enterprise ABM platforms.

How to Choose the Right Intent Data Platform

The right platform depends on three things: what type of intent data you need, how you plan to activate it, and your budget.

If you need broad third-party coverage to feed into your existing stack, start with Bombora. If you want predictive AI and full ABM orchestration, evaluate 6sense or Demandbase. If you sell SaaS and want the highest-fidelity signal, G2 Buyer Intent is hard to beat. If you sell to IT buyers, TechTarget's contact-level data is unique. And if you're a smaller team wanting website intent without enterprise pricing, Warmly is worth a look.

The strongest programs layer multiple signal types. A prospect who visits your pricing page (first-party), reads G2 reviews in your category (second-party), and has been researching your problem space across the web (third-party) is a fundamentally different lead than one who triggers a single signal. For a deeper breakdown of how to evaluate and activate intent data, read our complete guide to intent data platforms.

One more thing: intent data tells you who to target, not how to reach them. Once you've identified in-market accounts through intent signals, you still need verified contact information — direct emails and mobile phone numbers — to actually engage the right people. That's where connecting intent data to your enrichment workflow becomes critical. Tools like FullEnrich bridge that gap by waterfalling across 20+ data providers to find verified contact details for the accounts your intent data surfaces.
