Why teams replace Common Room
The published starting price is $2,500/month billed annually for the Essential plan (5 seats, up to 100k contacts), with the Advanced and Enterprise tiers priced custom - there is no free plan or self-serve low tier, so solo founders, small SDR teams, or anyone wanting to try the product without a sales conversation will find the entry cost prohibitive. Research and prospecting credits (RoomieAI credits, Prospector credits) are metered and capped per plan, with additional credits sold as add-ons, so heavy AI-agent usage carries incremental cost beyond the base subscription.
Common Room current baseline
Common Room sells itself as a replacement for stitching together a CDP, an enrichment vendor, an intent-data feed, and a sales engagement tool: it ingests first- and third-party signals into one buyer record (Context360) and offers RoomieAI agents and a Revenue Control Plane to turn those signals into prioritized, personalized outreach.
- Context360: unified buyer-intelligence record combining first-party (CRM/product/marketing) and third-party signal data
- Person360: waterfall enrichment and identity resolution across contacts
- RoomieAI: AI agents for account research, contact research, message personalization, and prospecting
- Signals: job changes, website visits, product-led-growth usage, and dark-funnel detection
- Segments, workflows, and automated plays for routing and alerting on signals
- Published starting point
- $2,500/month (billed annually, Essential plan)
