Enrich any lead, right where you find them.
The Netounim browser extension brings verified emails, mobile phones and one-click sequencing to every professional network you already spend your day on.
Available on every modern browser.
Same package, same code, signed and reviewed by each store.
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.
Four clicks to your first enrichment.
Under a minute, no terminal, no developer mode. Same flow on every browser.

- 3Sign in once
Open the toolbar icon, sign in with your Netounim credentials (or Google / Microsoft SSO). The session is scoped to your workspace.
- 4Start 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.
