What it does

Six superpowers, no tabs to babysit.

One-click on every profile

Find verified emails + phone numbers directly from any professional network profile — no copy-paste, no manual lookups.

Bulk-grab search results

Sweep an entire results page into your workspace in one shot. Filters, lists and saved searches all become enrichable in seconds.

Phone Waterfall, inline

Trigger our multi-source phone cascade right from the sidebar. Live carrier validation tells you mobile vs. landline before you call.

Verified emails only

Every address is run through MX + SMTP + catch-all + disposable checks before it lands in your CRM. No more 5% bounce rates.

Push to any workflow

Send freshly enriched leads straight into a sequence, a saved list, or a webhook. The extension is a doorway, not a dead end.

Encrypted local cache

The extension stores nothing about the people you research in plaintext. AES-encrypted cache, cleared on sign-out, never synced to disk.

Install

Four clicks to your first enrichment.

Under a minute, no terminal, no developer mode. Same flow on every browser.

  1. 1
    Click "Add to Chrome"

    Pick your browser from the badges above. You'll land on the official Web Store listing — verified publisher, signed package, no sideloading.

  2. 2
    Confirm permissions

    Approve the install prompt. We ask for the minimum set: read tab URL and contents on the supported professional networks only — no all-sites access.

  3. 3
    Sign in once

    Open the toolbar icon, sign in with your Netounim credentials (or Google / Microsoft SSO). The session is scoped to your workspace.

  4. 4
    Start enriching

    Open a profile or a results page. The Netounim button appears next to every contact you can enrich. That's it — you're done.

Permissions — and why we ask.

The extension is open-source-friendly: every line that handles your data is auditable through the Web Store's unpacked source view.

  • Read the URL of the active tab

    So we know whether to inject the enrichment button on a supported page.

  • Read DOM content on linkedin.com (+ subdomains)

    To extract the visible name + company so we can resolve the email.

  • Storage (≈ 200 KB)

    Caches your session token and a small AES-encrypted recents list.

  • Network — api.netounim.com only

    Every API call goes to our own backend. No third-party trackers, no telemetry beacons.
