LinkedIn content workflow for agencies and ghostwriters: plan, draft, get client approval, publish, and track results.
Postline is built for agencies and ghostwriters who manage LinkedIn for multiple clients at once. It runs a content calendar, drafts posts with two separate AI assistants (one for pipeline strategy, one for individual post writing), routes drafts through client approval, publishes on schedule, and reports on performance — while keeping each client's voice separate inside one dashboard. It's built by a Hamburg, Germany team, Mind Nexus GmbH, founded in 2023, and Postline itself has been in production since January 2025. Pricing is per connected LinkedIn profile with unlimited posts and AI usage included, plus an optional add-on for inviting clients and teammates.
$30/month per connected LinkedIn profile with unlimited posts and AI usage; a $10/month add-on unlocks client/teammate invitations.
Use tool ↗Postline is built for agencies and ghostwriters running LinkedIn for several clients at once, with a client-approval step and per-client voice separation that a single-user writing tool doesn't need. It's priced per connected profile, so cost scales directly with client count.
