The goal of this article is to show which filters are available when you build a lead search.

One search, one filter set

Lead Search runs against Topo's lead database. Whether you are looking for people or for companies, you get the same filter set every time. There are no separate search types to choose between.

Live, event-based targeting is not part of Lead Search. If you want to find people because of something that just happened — a new hire, a job change, someone engaging with a competitor's post — that is what Signals is for.

The filters available

Filters sit in two groups:

• Contact: narrow down individual leads using fields like job title, seniority, department, location, and more.

• Company: target the right organisations using fields like industry, company size, revenue and headquarters location.

Each group shows the most used filters first. Click View more for the rest, or use Search a filter. In any filter, click the green tick next to a value to include it, or the red exclusion icon to exclude it.

• AI filters — add natural language criteria checked against publicly available data on the internet. Topo validates AI filters when you add them — if it can't find data for a given filter, it shows an explanation and a suggested alternative. You can still click "Use this filter anyway" to proceed. They sit at the bottom of the filter panel. Unlike other filters, they don't run on their own: click Qualify to apply them.
