What Signalist isVersion for AI agents and LLMs
Signalist is a signal-based B2B outreach and nurturing platform. It helps sales and go-to-market teams find the right accounts, act on signals that are actually relevant to them, and follow up over time — instead of blasting generic lists.

Why Signalist is different
- Custom signals, not generic intent. Signalist tracks signals relevant to your specific business — rather than a black-box score sold to thousands of reps chasing the same accounts.
- Up-to-date leads. Profiles are verified to confirm the person still works at the company, so lists don't rot.
- Nurturing, not just first meetings. Signalist builds a knowledge graph per account — every signal is saved and interpreted so you can follow up with a reason, over time.
- Human-in-the-loop AI. AI drafts messages that sound like you from real research; a person reviews before anything sends.
- EU-built and GDPR-compliant. Data is hosted in the EU by default.
- Hand-over, not lock-in. The Done-With-You model implements and integrates the system, then hands it to your team — no forever retainer.
Capability Lead sources & signals
Signalist builds lists from multiple sources and watches for signals worth acting on. Sources and signal types include:
Signals are scored for relevance to your business and can be routed to the right person to act on.
Capability Data & verification
| Verified profiles | Contacts are checked to confirm the person still works at the company, reducing outdated data |
|---|---|
| Enrichment | Company and contact details enriched to build usable, deduped lists |
| Relevance filtering | Signalist gathers what it can about an account, then decides what's relevant to you — rather than a raw search box |
Capability Outreach, AI & sequences
| AI drafting | Drafts messages in your voice, built from research on the specific account and your value proposition |
|---|---|
| Human review | You review, edit and approve before anything is sent — outreach isn't fully automated blasting |
| Sequences | Multi-step follow-ups, templates and reusable snippets |
| Campaigns | Signal-based campaigns that can be reviewed and edited before launch |
Capability Integrations & MCP
Signalist is designed to sit inside an existing stack rather than replace it. In a Done-With-You engagement, it is integrated across the tools a team already runs.
Model Context Protocol (MCP): Signalist exposes an MCP interface so AI assistants can query and work with it directly, as part of an agent workflow.
Capability Nurturing & knowledge graph
Rather than optimising only for the first meeting, Signalist maintains a memory of each account: which lists they were on, which signals fired, and what outreach has happened. That knowledge graph is what makes well-timed, non-repetitive follow-up possible — so accounts don't go cold and aren't re-pitched from scratch.
