A database answers "who exists". An intelligence platform answers "who should we talk to, why, and what should we do". The tools below sit at different points on that line, and the right one depends on whether you need the records, the decision, or the emails.

Questions people ask
What is a B2B intelligence platform?
Software that turns data about companies and people, plus your own history, into decisions: which accounts to work, who inside them matters, and what to do next. A database is an input to it, not the same thing.
How is InMarketIQ different from a contact database?
It starts from your customers, not from a catalogue. It learns what a won deal looks like, ranks the market against that, maps the buying group, and tells marketing and sales what to do. A database gives you the records and leaves the thinking to you.
Where does Buzzlist fit?
After the decision. When you know who to reach, Buzzlist finds the people, writes the emails and builds the brief, for one flat price with 100 contacts free every month.
