What Gets Enriched
ClientX populates the following fields on every lead record where data is available:| Field | Source |
|---|---|
| Company name | Apollo.io → IP identification → Clearbit (in priority order) |
| Industry | Apollo.io |
| Company size | Apollo.io (estimated headcount) |
| LinkedIn URL | Apollo.io |
| Job title | Apollo.io |
| Phone number | Apollo.io (on-demand reveal) |
| Location | Apollo.io, IP geolocation |
| Company domain | Apollo.io → IP identification → Clearbit (in priority order) |
Data Sources
ClientX uses four enrichment sources in a waterfall sequence. Each stage only runs if the previous stage left a field blank, so you always get the most authoritative data available without redundant lookups.Apollo.io — Company & Contact Data
Apollo.io is the primary enrichment source for person-level data. When a lead’s email address is known, ClientX queries Apollo to retrieve their job title, LinkedIn URL, company name, company domain, company industry, and estimated headcount.Phone numbers are revealed on demand using Apollo’s mobile credits — click Reveal Phone on any lead card to trigger this lookup.Requires your Apollo API key — connect it in Integrations → Apollo.io.
Hunter.io — Email Verification & Decision-Maker Search
Hunter.io is used to find verified email addresses for decision-makers at a target company, and to validate existing email addresses before outreach. Hunter searches by company domain and returns contacts sorted by confidence score. It also acts as a fallback for decision-maker search when Apollo is unavailable.Requires your Hunter API key — connect it in Integrations → Hunter.io.
IP-Based Company Identification — No Setup Required
Even before a visitor shares their email, ClientX resolves their company from their IP address. Corporate IPs are matched to a company name and domain; consumer, ISP, VPN, and datacenter IPs are filtered out automatically so you only see real business visitors.This source requires no API key and runs automatically for every website visitor.
Clearbit — Company Name Fallback
If a lead’s company name is still unknown after the Apollo and IP stages, ClientX performs a final lookup against the Clearbit Autocomplete database using the lead’s work email domain or the domain resolved from their IP. Only exact domain matches are used — no guessing. This stage requires no API key and runs automatically as a last resort.

Find Leads by Company
Use Leads → Find to proactively search for contacts at any company — even ones that haven’t visited your site yet. Enter a company domain and ClientX uses Apollo (with Hunter as a fallback) to find decision-makers: founders, C-suite executives, VPs, directors, and managers.Go to Leads → Find
Select Find from the Leads section in the sidebar, then choose the Quick find tab.
Describe your target audience
Type a plain-English description of the contacts you’re looking for — for example, “Get me Heads of Sales at B2B SaaS companies with 50–200 employees in the US” — and press Enter.ClientX uses AI to parse your description into the correct Apollo search parameters (titles, seniority levels, company size ranges, locations, and industry keywords) before running the search.
How Enrichment Runs
Enrichment runs automatically in the background as soon as a lead’s email address or company name becomes known. You’ll see a loading indicator on newly captured leads while enrichment is in progress — it typically completes within a few seconds. You don’t need to trigger it manually for leads captured through the chat widget, forms, or LinkedIn.
