# Provider: signal add-ons (tech stack, jobs, traffic, maps, email)

Person Search and Segment Search results carry a set of small, single-purpose
add-on cards on top of the main contact and company data — signals that
help you judge fit or timing rather than reach someone. Five exist in
ListPlus today: **Tech Stack**, **Open Jobs**, **Google Maps Profile**,
**Web Traffic** and **Email Infrastructure**; a sixth, **Deep Company
Profile**, bundles the first two with funding data in one lookup.

**What it delivers.** Tech Stack: technologies detected on the company
website. Open Jobs: active job postings — a buying-intent signal. Google
Maps Profile: rating, review count, phone and address. Web Traffic:
monthly visits and global rank. Email Infrastructure: the domain's mail
provider and SPF/DMARC posture. Deep Company Profile: funding rounds, tech
stack and open job titles together in one card.

**Where in ListPlus.** All six show as cards in the company section of the
Person Search / Segment Search result profile (the same drawer used from
either finder); exact prices are in "Person Search: basics and profile
add-ons."

**Inputs needed.** A domain for Tech Stack, Web Traffic and Email
Infrastructure; a company name for Google Maps Profile; a LinkedIn company
URL or company name for Open Jobs; a domain for Deep Company Profile.

**Coverage & freshness.** Each card looks up its source live at the moment
you click it; a card with nothing to show (no jobs open, no detected
technology) simply reports "Nothing found" instead of returning stale
data.

**Credits & charge rule.** Every card is charged only on a hit — a miss
costs nothing. Exact per-card amounts are in "Person Search: basics and
profile add-ons."

**What the provider receives from us.** Only the one identifier the card
needs — a domain or a company name — never the rest of your list or
search.

**Company seat, data location, legal basis.** These cards each pull from
a different specialised data source; none is named individually in these
docs. Details are available on request from support@listplus.ai.

**Caching.** Not cached — each card runs again even for a company you've
already looked up.

## FAQ

### What signal add-ons can I see on a Person Search or Segment Search result?

Five: Tech Stack, Open Jobs, Google Maps Profile, Web Traffic and Email Infrastructure, plus Deep Company Profile, which bundles funding data, tech stack and open job titles into one lookup.

### What does "Open Jobs" tell me?

Active job postings for the company — a signal it may be growing or hiring into the area you care about. It needs a LinkedIn company URL or a company name.

### What does "Email Infrastructure" show?

The domain's mail provider and its SPF/DMARC setup — useful for judging how a domain sends email before you rely on an address at it.

### Are these signal cards charged even if they find nothing?

No. Every card is charged only when it returns data; a miss costs nothing. See "[Person Search: basics and profile add-ons](https://listplus.ai/en/help/plans-credits-billing/price-list-profile-add-ons)" for the exact per-card price.

### What does "Deep Company Profile" add over the individual cards?

It's one lookup that returns funding rounds, tech stack and open job titles together, instead of running Tech Stack and Open Jobs separately.

### Do these add-ons work in a list's Enrich menu, or only in search results?

Mostly as cards in the Person Search / Segment Search profile drawer. Tech Stack is also available in a list row's record panel. None of them is a button in a list's Enrich menu.
