GTM Workspace - Powered by ZoomInfo

Note: GTM Workspace is the upgraded version of ZoomInfo Sales and ZoomInfo Copilot. GTM Workspace is a unified sales execution platform that empowers account executives and account managers to run their entire book of business from a single workspace. By bringing together CRM data, ZoomInfo intelligence, engagement history, and buying signals into one consolidated view, GTM Workspace eliminates the constant context-switching that prevents sellers from doing their best work. At the core of GTM Workspace is an AI assistant that understands the full context of a rep's territory - their accounts, open opportunities, past conversations, and real-time signals - enabling natural language commands that drive real action. Sellers can instantly prepare for meetings, monitor account health, prioritize pipeline, and identify the best prospects to pursue, all without leaving a single interface. GTM Workspace integrates directly with Salesforce, maintaining bidirectional, real-time sync so CRM data stays current automatically. Flexible, spreadsheet-style Views allow reps to slice and analyze their accounts, contacts, leads, and opportunities exactly the way they work - with ZoomInfo firmographic, technographic, and intent data enriched directly alongside CRM fields. Purpose-built for the way modern sales teams operate, GTM Workspace requires no training, no agent building, and no engineering projects. It works immediately out of the box, delivering day-one value on top of the data foundation teams already rely on. The result: sellers spend less time stitching together information across disconnected tools and more time doing what they do best - building relationships and closing deals.

SalesIntel

SalesIntel is the pipeline generation platform for GTM teams. We help sales and marketing teams find accounts that match their ideal customer profile, surface the buying signals that show who's in-market, and use AI agents to automate manual prospecting work. That gives teams more time to focus on what humans do best: building relationships with prospects. Everything runs on a foundation of human-verified B2B data. Rather than guessing which accounts to prioritize, teams get verified contacts, deep company and technographic detail, and real-time buying signals, so every account and contact is enriched with the context needed to engage at the right moment. With that data and signal foundation in place, AI agents take on repetitive GTM tasks such as account prioritization, research, and enrichment. They filter for accounts that match a team's ICP, then surface the right leads for the right rep, cadence, or CRM record, reducing the time spent searching for information. SalesIntel's core capabilities include: Data Management: human-verified contact and company data that keeps CRM records accurate and current. ICP Modeling: tools to define, refine, and enrich an ideal customer profile so teams know exactly who to target. Inbound Lead Management: enrichment the moment a lead converts, so context flows directly into existing workflows. Outbound Prioritization: named account prioritization synced with Salesforce and HubSpot, paired with a no-code workflow builder for building signal-triggered plays. GTM Execution: tools that turn account and signal intelligence into targeted advertising and outreach. Together, these capabilities give sales and marketing teams a shared view of the same data, the same signals, and the same accounts, helping them build pipeline with less manual work and more informed context throughout the buying journey.
