The moment ClientX knows a lead’s email address or company name, it starts filling in the blanks. Job title, company size, industry, LinkedIn profile, phone number — all of it appears on the lead record automatically, sourced from the data providers you’ve connected. You get a fully-researched prospect without lifting a finger.

What Gets Enriched

ClientX populates the following fields on every lead record where data is available:
FieldSource
Company nameApollo.io → IP identification → Clearbit (in priority order)
IndustryApollo.io
Company sizeApollo.io (estimated headcount)
LinkedIn URLApollo.io
Job titleApollo.io
Phone numberApollo.io (on-demand reveal)
LocationApollo.io, IP geolocation
Company domainApollo.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

1

Go to Leads → Find

Select Find from the Leads section in the sidebar, then choose the Quick find tab.
2

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.
3

Review and save results

Results appear in a table scored against your ICP profile. Select the contacts you want to add to your pipeline and click Save to workspace. Each saved contact becomes a full lead record.
You can also search by uploading a CSV from Apollo, LinkedIn Sales Navigator, or any contact database. Go to Leads → Find → Import CSV and drop your file — ClientX auto-detects common column names like email, first name, linkedin, company, and title.

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.

Credits and Pricing

Apollo.io and Hunter.io operate their own credit systems independently of your ClientX subscription. Each API call to Apollo or Hunter consumes credits from your plan on those platforms. Monitor your usage directly in your Apollo and Hunter dashboards to avoid running out mid-month. ClientX does not bill you for enrichment calls — it passes them through to your connected accounts.
