Reachvite helps small B2B teams and independent professionals start new conversations on LinkedIn. Define a target audience with filters for industry, company, job title, location and language; Reachvite proposes matching profiles with a short reason for each, and you approve the batch. The Chrome extension sends the invitations at a human pace and stops for 48 hours if a warning appears. Plans: 19 USD/month or 190 USD/year, with no setup fee.
