LinkedIn Sales Navigator is LinkedIn's premium prospecting layer for B2B sellers. Its job is to turn the largest professional graph into a targeted account and lead list, using more than 50 filters across role, company, seniority, geography, headcount, and tenure that free LinkedIn search cannot reach. You build saved searches and lead lists, then get alerts when people change jobs, post, or show buying signals. InMail messages contacts outside your network, TeamLink surfaces warm paths in, and higher tiers sync the activity into your CRM. In a GTM stack it is the targeting and signal source at the top of funnel. You define an ICP here, pull the matching people, then enrich and route them through the rest of the system rather than messaging one prospect at a time inside LinkedIn. At Nebor we treat Sales Navigator as a data source we scrape in real time through LeadsFactory.io, not a tool we log into to send by hand. We reach for it when a client's ICP is best defined inside its filters. When that fits, we set the ICP with its filters, pull the audience live via LeadsFactory.io, and feed it into Clay for enrichment and verification before any sequence runs. The job-change alerts also flag timing, so we know when an account is worth a fresh play rather than guessing at the window.
