SocialOS monitors social signals from ideal buyers, organizes Voice of Customer insights, and supports personalized outreach and referrals. Its four listening modes are Topic Search, Comment Campaign, Own Engagement, and HubSpot Segment. ICP filters score engagers using criteria such as title, seniority, company size, industry, location, and tech stack. VoC Insights surfaces themes, engagement patterns, tone, and conversation gaps; Content Studio drafts LinkedIn posts from those themes and is labeled Beta. Campaign workflows can include connection requests, profile views, waits, branches, and messages, with AI drafts available for review before sending. Referral campaigns match partners’ LinkedIn networks to an ICP and prepare introductions for partner approval. SocialOS describes bidirectional HubSpot CRM sync, Slack workflow notifications, and connections to LinkedIn sender profiles. It also offers an MCP server and CLI with approval steps before actions affect LinkedIn. The web-based service has a free plan and paid plans beginning at $199 a month. Plans meter actions, and the terms place responsibility for connected-platform rules on customers while noting LinkedIn may restrict or terminate accounts using tools like this.
