The story
Turn your LinkedIn network into a pipeline.
Challenge
- Scrolling profiles one by one to find the right people took hours.
- Names, titles and companies were copied into spreadsheets by hand.
- Most automation tools ask for your LinkedIn password or session cookie.
- Tools that route activity through unknown proxy servers get accounts flagged.
What we did
- Connect without credentials: The Chrome extension links LinkedIn in one click from the session the user is already signed in to. No password or cookie is ever shared with us.
- Sync the whole network: Connections sync automatically into a searchable list, so there is no copy-paste and the list stays up to date.
- Filter to ideal leads: Advanced filters by name, job title, company, school, and current or past companies narrow thousands of connections to the right few.
- Reach out at a human pace: Personalized templates, a side panel for qualifying leads and built-in safe limits keep outreach fast and natural.
Result
- 25,000+ LinkedIn connections synced and 75,000+ messages sent from users' own browsers.
- A 32% average reply rate across outreach sent through Zavaro.
- Setup in about 2 minutes, with no LinkedIn password or cookie ever shared.
