Prospeo is the licensed B2B contact database behind **Segment Search**, and also
powers several email, phone and company-contact lookups elsewhere in
ListPlus.

**What it delivers.** Filtered audience results in Segment Search; a verified
work email plus the company's main phone number via "Contact Brief"; a
verified personal mobile via "Reveal Mobile Number"; and up to 25 company
decision-makers with contact teasers via "Company Contacts (Prospeo)."

**Where in ListPlus.** The Segment Search page; "Contact Brief (by LinkedIn
URL)" and "Contact Brief (by Name & Company)" (Enrich menu, record panel,
single-cell fill window) — in the Enrich menu, Prospeo's 2-credit name
lookup can also appear as "Find Email (by Name & Company)"; "Verified
Email & Company Phone" in Person Search; the Reveal · 12 Cr mobile button
under a profile's Reachability section, also available in the record panel
and the single-cell fill window as "Reveal Mobile Number"; "Deep Company
Profile" (3 credits) and "Company Contacts" on a Person Search profile, and
"Company Contacts (Prospeo)" in the record panel.

**Inputs needed.** For Segment Search, your filter selections (role, industry,
seniority, company size, location, funding stage and more) — Prospeo
receives the filters, not any of your existing contacts. For a lookup, a
LinkedIn profile URL, or a first name + last name + company name/domain.
Company Contacts needs a company domain.

**Coverage & freshness.** By Prospeo's own figures: roughly 300 million
profiles and 143 million verified email addresses, refreshed weekly — that
claim is the provider's, not independently verified by ListPlus.

**Credits & charge rule.** Charged only when Prospeo returns a value (a
Segment Search page with zero matches is free). Exact amounts are in "Price
list: what every action costs," "[Get emails and phone numbers](https://listplus.ai/en/help/find-contacts/reveal-email-and-phone)" and
"[Person Search: the profile drawer and its add-ons](https://listplus.ai/en/help/find-contacts/profile-and-add-ons)."

**What the provider receives from us.** For Segment Search, only your search
filters. For a lookup, only the identifier needed: a LinkedIn URL, a name
and company, or (for Company Contacts and Deep Company Profile) a company
domain. It never receives your whole list.

**Company seat, data location, legal basis.** ListPlus doesn't publish
Prospeo's registered seat or data location in this help center. Email
support@listplus.ai and we'll send you the details.

**Caching.** An identical Segment Search you repeat within 30 days is
free. A Contact Brief or mobile reveal that returned data is reused for 7
days in your account, so repeating it sooner doesn't charge again; lookups
that found nothing, and Company Contacts, are run again.

## FAQ

### What does Prospeo do inside ListPlus?

Prospeo is the licensed B2B contact database behind Segment Search, and also finds verified work emails, company phone numbers, personal mobile numbers, and company decision-maker lists elsewhere in ListPlus.

### How current is Prospeo's data?

By Prospeo's own figures, its database holds roughly 300 million profiles and 143 million verified email addresses, refreshed weekly — that's the provider's claim, not independently verified by ListPlus.

### What does Prospeo receive when I run a Segment Search?

Only the filters you set (role, industry, seniority, company size, location and so on) to match against its database — not any data from your existing lists.

### What does Prospeo receive when I look up one person?

Only the identifier needed for that lookup: a LinkedIn profile URL, or a first name, last name and company name or domain. It never receives the rest of your list.

### Does repeating a Prospeo lookup cost credits again?

An identical Segment Search repeated within 30 days is free, and a Contact Brief or mobile reveal that returned data is reused for 7 days in your account without charging again. Lookups that found nothing are run again, and Company Contacts is billed again on each hit.

### What is "Company Contacts (Prospeo)" in the record panel?

A lookup that returns up to 25 decision-makers at a company, with masked email and mobile teasers, added to your list as new rows. It needs a company domain and appears in the record panel's company section. It costs 2 credits, charged only when contacts are found; it is also a Person Search add-on called "Company Contacts."

### Where is Prospeo based, and is it GDPR-compliant?

ListPlus doesn't publish Prospeo's registered seat or data location in this help center. Email support@listplus.ai and we'll send you the details.
