Understanding Filters When Building a Lead Search
Last updated: September 8, 2026
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
Contact filters — narrow down individual leads using fields like name, job title, seniority, department, location, and more.
Account filters — target the right organisations using fields like industry, company size, revenue, headquarters location.
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.

Additional filter tools
Edit Filters with AI
The Edit Filters with AI button (top of the filter sidebar) lets you reprompt the agent to generate a new set of filters based on a revised description. Use it when the initial filters don't match your targeting intent.
Organisation Context filters
When Organisation targeting is active, the filters generated from your Organisation Context appear as normal filter entries in the sidebar — highlighted in green. You can edit or remove them like any other filter.
