Overview
How each tool is described
RB2B
What is RB2B?
RB2B is a B2B website visitor identification platform that helps businesses identify companies and professional visitors browsing their websites and turn anonymous website activity into sales intelligence. It provides visitor data, enrichment, and routing workflows that allow sales and marketing teams to understand who is engaging with their website and decide how to follow up.
- Website visitor identification: RB2B helps businesses reveal information about anonymous website visitors, including company details and professional profiles, allowing teams to understand which organizations are showing interest in their content or products.
- Lead activation workflows: identified visitor information can be delivered into sales workflows through integrations such as Slack and CRM systems, helping teams notify relevant people and take action on high-interest visitors.
- Intent-based prospecting: teams can use website activity signals, such as pages viewed and engagement patterns, to prioritize accounts that may be worth contacting.
- Revenue team use cases: RB2B is designed for B2B sales and marketing teams that want additional visibility into website traffic and prospect activity, particularly when many potential buyers visit without completing forms.
RB2B is most suitable for companies with existing website traffic that want to uncover potential prospects from anonymous visitors and connect website engagement data with outbound sales processes.
Common Room
What is Common Room?
Common Room is a go-to-market intelligence platform that helps revenue teams identify potential buyers by combining customer activity, company data, community interactions, product usage, and other market signals into unified customer profiles. It is designed to help sales, marketing, and revenue operations teams understand buyer intent, prioritize accounts, and activate signals through existing workflows.
- Buyer intelligence: Common Room’s Person360™ identity resolution connects activity from different sources to individual and account profiles, helping teams understand engagement across fragmented data points.
- Signal tracking: the platform captures signals from sources such as websites, product activity, communities, CRM systems, and other business data sources to help teams identify accounts and people showing relevant interest.
- AI-assisted workflows: Common Room’s AI capabilities help teams research accounts, summarize customer context, identify relevant signals, and support outreach preparation using available customer intelligence.
- Revenue activation: teams can use Common Room insights within existing workflows through integrations and tools such as Salesforce, Slack, email workflows, and browser-based prospecting experiences.
Common Room is most useful for companies with complex buyer journeys, community-led growth motions, product-led sales strategies, or account-based sales programs that need to combine multiple sources of customer intelligence into actionable revenue workflows.
