Best Buying Intent Signal Tools for B2B 2026

Intent data is the most over-marketed and under-understood category in B2B sales tech. In 2026 there are three distinct signal sources and seven tools worth comparing, not one monolithic 'intent platform'. Pricing re-verified 29 July 2026 where noted.

What 'intent' actually means

Intent is not one thing. It is three:

1. Third-party intent (Bombora, G2): anonymous account-level topic consumption across publisher networks.
2. First-party intent (Clearbit, Koala, Warmly): deanonymized website visitors on your own domain.
3. Engagement intent (Trigify, UserGems, LinkedIn Sales Navigator): prospect actions on social or job boards.

Each surfaces different 'in-market' moments. Serious teams use all three, weighted differently per motion.

The three signal sources

Third-party intent

• Bombora: Category standard. Cooperative of ~5,000 publishers. 12,000+ topics trackable.
• G2 Buyer Intent: Intent data from G2 category pages. Useful if your category is on G2.

First-party intent

• Clearbit (HubSpot Breeze Intelligence): Reveal anonymous visitors, enrich known ones.
• Koala: Product-led sales signals from your app.
• Warmly: Website visitor ID + AI chat.

Engagement intent (LinkedIn-heavy)

• Trigify: LinkedIn engagement signal detection. $40/mo Starter, $199/mo Max, verified July 2026.
• UserGems: Job-change and champion tracking. Enterprise-only.
• Satellyte: Six signal types, including social engagement across LinkedIn, X, and Threads, plus funding, hiring, tech stack changes, news events, and technology lists. From $99/mo.

Tools compared

Trigify pricing verified 29 July 2026. It restructured during the year, so older comparisons quoting $149 Essential are stale. Our Trigify pricing explained page covers the current tiers and the credit math.

Decision framework

• Low budget, LinkedIn-heavy: Trigify Starter at $40/mo is the cheapest way to test whether engagement signals convert for you. Budget for Max at $199/mo if they do, since Starter caps tracked profiles at 50.
• PLG SaaS: Koala plus first-party, skip third-party.
• Enterprise ABM: Bombora plus 6sense, expect enterprise contracts.
• Multi-source warm outbound: Satellyte or an equivalent that unifies social engagement with hiring, funding, and tech stack changes in one feed.
• Champion tracking specifically: UserGems, narrow use case executed well.

Caveats worth an editor's eye

• Clearbit is now HubSpot Breeze Intelligence; standalone pricing is gone.
• Bombora and G2 intent signal strength varies by industry; run a 90-day pilot before annual.
• 'Intent' tools claim predictive accuracy; validate on closed-won accounts before budget defense.
• Koala and Warmly entry figures are reported, not re-verified. Trigify verified 29 July 2026.
