LinkedIn growth, finally
visible and in control.

Yes — Businium enforces strict daily limits, human-like delays, and gradual warm-up for new accounts. Safety is the foundation, not a toggle. Default rails on, you're indistinguishable from a slightly more disciplined version of yourself.

Most tools run from remote servers using your cookies — LinkedIn detects that. Businium runs in your real Chrome session, so every action is indistinguishable from manual use.

Never. The extension works inside your existing LinkedIn session. We don't store, transmit, or even see your credentials.

You add your OpenAI / Anthropic / Gemini key in settings. Businium uses it to write personalised connection requests and follow-ups. Your key, your model, your data, your bill (avg $2/mo).

Paste a LinkedIn search URL when creating a campaign. The extension scrapes results in the background and enrolls discovered contacts into the sequence — no CSV export, no manual steps.

Yes. No contracts, no lock-in. Cancel from your dashboard and your subscription ends at the current billing period.

Posts publish at the exact time slots you configure in Posts → Settings. The Chrome extension publishes from your real browser session, so posts appear as if you typed and submitted them manually. You can require approval before any post goes live, or enable hands-free auto-publishing.

Job Campaigns continuously discover LinkedIn roles, score fit, screen company and posting risk, and place qualified applications into an auditable queue. Shadow mode keeps submission under review; operating limits and hold controls remain visible in the workspace.

Yes. The v1 REST API covers campaigns, contacts, scheduled posts, feed campaigns, accounts, personas, and Job Campaigns. API keys are scoped and revocable, and contact sync supports idempotent upserts by LinkedIn profile URL.
