kalko10 best intent data providers in 2026
The best intent data provider depends on where your buyers read. Bombora covers a co-op of B2B publishers, G2 covers software review sites, and TechTarget covers IT buyers. Kalko adds the public reason behind the interest, such as a job post.
Key takeaways
- Bombora collects intent from a co-op of thousands of B2B publisher sites (Bombora).
- Most third-party intent data names the company, not the person who read the content.
- Bombora, G2 Buyer Intent and TechTarget Priority Engine do not publish prices.
