Signal Checker Blog Integrations FAQ Contact PricingSignal Tracker watches your target companies 24/7, detects 40+ types of buying signals, and turns each one into a warm, ready-to-send email — sent from your own inbox.
Email Sarah Klein (VP Sales) — budget allocation window is open
Reach out to Daan Vermeer (CEO) — scaling teams buy tooling
Pitch localization support to their new market lead
Most tools do one of these. Signal Tracker does all six — that's why a signal becomes a reply, not just a notification.
Every tracked company is monitored daily across 40+ signal types — funding, hiring, expansion, product launches, partnerships, leadership changes, risk events. Noise filtered, duplicates removed, everything timestamped.
Browse all signal typesSignals are scored 0-100 by how actionable they are for you — your product, your ICP, your geography. The board tells you who to contact today, who can wait, and who to skip. No more staring at a list wondering where to start.
Tell it once what you sell, who you sell to, and how you talk. From then on, every draft pitches the right product, with the right angle, in your voice — with guardrails for things it should never say.
Not "Hi {first_name}, I hope you're well." Every draft opens with the actual event, explains why it matters, and connects it to what you sell. The right contact is found and email-verified before you ever see the card.
Turn it on and signal-triggered emails queue themselves — with a review window before anything goes out. Daily caps, send windows, natural gaps between sends, and per-company cooldowns keep your sender reputation intact.
See which signals turn into conversations and which follow-ups get replies. Sync everything to Pipedrive or HubSpot so your pipeline reflects reality — without manual data entry.
Nothing sends without your review window — even on auto-pilot.
Emails go through your own Gmail/Outlook/SMTP. Replies land where you work.
Daily caps, send windows and cooldowns protect your domain.
We track companies, not people's private data. EU-based processing.
The free plan is genuinely free — upgrade only when the replies justify it.
