Sales Intelligence Tools: What They Do and How to Choose One

The categories of sales intelligence tools, what each does well, and the questions to ask before you buy.

September 28, 2026

"Sales intelligence" covers very different products. Choosing well starts with knowing which job you need done.

The main categories

  1. Contact databases — emails and phone numbers at scale.
  2. Intent data — which companies are researching topics.
  3. Technographics — what software a company uses.
  4. Prospect intelligence — researched, contextual briefs on a specific account and person: why now, what pains, what to say.

Most teams have a database. What they lack is the last category: turning a name into a reason to reach out.

Questions to ask before buying

  • Does it cite sources for its claims, or invent plausible text?
  • How fresh is the data? Are old signals filtered out?
  • Does it score accounts against my ICP?
  • Can it produce outreach, not just data?
  • Does it work in the languages my buyers speak?
  • What does it cost per useful output, not per seat?

Red flags

  • Personalization with no traceable evidence.
  • Scores without explanations.
  • Annual contracts before you can test real accounts.
