Signal-Stack maps relationship overlap across your team and tells you exactly who should engage — and how. Pre-call briefs, warm intro paths, and network intelligence in one platform.
How it works
Upload LinkedIn exports across your team. Connect Gong, Gmail, Outlook, Salesforce, and HubSpot. Data stays scoped to participants — privacy-safe by design.
Network overlap, connection strength, seniority mapping, ICP matching, and account relevance — computed automatically across your entire org.
Shortlist targets, auto-generate personalized intro emails, review and send in bulk. Pipeline tracks every contact from shortlisted to meeting booked. Push to Apollo, trigger Zapier webhooks, enrich via Prospeo.
Core capabilities
Each capability feeds the next. Overlap data enriches intro paths. Intro paths inform outreach. Outreach drives signal scoring.
Detect shared connections across your entire org instantly. Two-tier matching — exact LinkedIn URL and name-plus-company — catches what simple dedup misses. See who on your team already knows your prospect before you reach out.
Network analysisIdentify the strongest path into any target account. Relationship scoring from endorsements, messages, recommendations, and invitation direction. Know not just who to reach, but who should make the introduction.
Intro pathsSee which companies your team has deep coverage in and where the gaps are.
Prevent duplicate outreach and internal collisions before they happen.
Rank opportunities by relationship strength, ICP fit, and seniority weight.
CSV export, outreach templates, contact shortlists, and one-click copy.
Shortlist prospects, track them through your funnel, and generate AI-personalized intro emails in bulk. Review, edit, then send — all from one pipeline view.
Pipeline & outreachOne click generates hyper-personalized intro request emails for every shortlisted contact. Uses relationship signals, user notes, ICP fit, and company intel to craft messages your connectors actually want to forward.
AI-poweredInside the product
Not another dashboard to stare at. Every view answers one question: who should engage, and what should they say?
