MassLink · Chrome and Firefox

LinkedIn prospecting without Sales Navigator.

MassLink works on the LinkedIn you already have. Capture a search or your connections, let AI sort them against your ideal customer, export to CSV or Excel.

  1. Step 1: Capture

    Run a search on LinkedIn like you normally would, or open your connections list. MassLink reads what's on the page.

  2. Step 2: Qualify

    Describe who you're looking for in plain language. AI scores everyone captured against it and tells you why.

  3. Step 3: Refine and export

    Narrow it down, then take it out as CSV or Excel.

Add to Chrome — free Add to Firefox — free

Free tier, no card. Pro US$19/mo, with a 14-day trial. No credits.

How we build

The same deal on every tool.

  • It does the work, not the admin around it.

    Each tool takes a job that would otherwise eat an afternoon and returns the finished thing. Not a dashboard about the job — the job.

  • No credits.

    Every plan has a set price. No balances to top up, no counter to watch, no working out what a run costs before you make it.

  • Try it before you pay.

    MassLink and MassBlocker have free plans. MassAdmin has a 30-day free trial with no card. Sign up or install it yourself: no demo needed.
