Gro v2 is an AI-powered sales platform that adds social signal monitoring to its existing prospecting engine. The key new feature in v2 is Content Search — it scans LinkedIn, Twitter/X, and other platforms in real-time for posts that indicate buying intent, then automatically triggers workflows: alerts, connection requests, comment drafts, and email sequences, all from one interface. Underneath that is a database of over 1 billion contact records with AI-driven propensity scoring that ranks accounts by likelihood to convert. The system coordinates multi-channel outreach (email + LinkedIn + others) and tries to collapse what used to be a stack of five or six point solutions — Apollo, Clay, Phantombuster, etc. — into one system. Gro v2 targets growth-focused B2B teams who currently have to stitch together multiple tools for their outreach stack. It offers a free tier, though the full intent-monitoring and automation features are presumably gated behind paid plans.

Reviewer scorecard
“Social signal monitoring that auto-triggers structured outreach is a real workflow upgrade. If the signal quality is high — not just keyword matching — this replaces three separate tools in the stack immediately.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“The '1B+ contact database' claim is table stakes in 2026, and every Sales AI promises to unify the stack. The real question is whether the intent signals are actually predictive or just keyword noise. No independent validation here.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
“Real-time social intent layered on top of structured outreach automation is the logical next step for B2B AI. The companies that nail signal fidelity will eat the legacy CRM market.”
“Auto-triggering comments and connection requests from detected 'intent' is the kind of feature that makes LinkedIn even more of a spam hellscape. I'd use this sparingly unless the personalization is genuinely thoughtful.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
