PhantomBuster is brilliant at the top of the funnel. It scrapes profiles, exports Sales Navigator searches, and finds emails through built-in credits and third-party providers. Then it hands you a spreadsheet. Nothing in that spreadsheet books a call. Reachium starts where the list ends. It runs the connection requests, the personalized follow-ups, the content that warms the room, and the inbox that catches the reply. You can scrape with PhantomBuster and act with Reachium. The two are not the same job.
PhantomBuster runs a Chrome browser in the cloud authenticated by your LinkedIn session cookie. That is browser automation, it sits against LinkedIn terms, and PhantomBuster's own documentation acknowledges accounts can get restricted even inside recommended limits. Reachium is built on the verified LinkedIn API. No cookie injection, no scraping your own session, no BYOIP setup. For teams who treat the LinkedIn account as a real asset, the connection method is the whole decision, not a footnote.
PhantomBuster can build outreach Flows with branching and a LinkedIn Outreach Phantom that auto-sends follow-ups. What it has no version of is a unified inbox, account warmup, a calendar, or an inbound content engine. So real pipeline still forces you to bolt on three more tools. Reachium bundles outbound campaigns, inbound content, lead magnets, a unified inbox, meeting detection, and a network CRM into one login. Fewer moving parts, fewer things that break.
PhantomBuster is an outbound and scraping machine. It does not help you post, build authority, or pull inbound replies. Reachium runs both directions. The AI content generator works a 4-bucket strategy, the lead-magnet builder builds and hosts the asset while trigger keywords on post comments fire automated DM delivery, and engagement campaigns warm prospects before you ever send a request. Outbound plus inbound on the same relationship is a different model than scrape-and-send.
PhantomBuster meters execution hours, email credits, and AI credits that all expire monthly with no rollover and no mid-cycle top-up. Hit the ceiling and campaigns hard-stop until the next billing cycle. Reachium charges $99 per LinkedIn account per month, $79 on annual billing, and the per-account rate steps down to $79 at 10 accounts, $65 at 50, and $50 at 100, with 500 AI credits included, cancel anytime, no contract. You scale by adding accounts, not by guessing how many execution hours next month needs.
