What is Signl?

Signl is a GTM data layer your AI agent queries directly: companies, buying signals and verified contacts, over MCP.

Updated Aug 20, 2026

Signl is the GTM data layer for AI agents. You connect it to Claude, ChatGPT, Cursor or another MCP-compatible client, and your AI can search companies by industry, geography, headcount and funding stage, track buying signals like funding rounds and hiring surges, and pull verified decision-maker contacts on demand. You only pay when a verified contact is delivered.

The three things Signl gives your agent

  • Companies. Search any market by industry, geography, headcount, funding stage and hiring activity.
  • Buying signals. The changes that make an account worth contacting now: funding rounds, hiring surges, technology adoption, leadership moves.
  • Verified people. Decision-makers at those companies with name, title, verified email and LinkedIn profile.

Each of those is a tool your agent calls in plain English. You do not build a query or export a CSV; you ask, and the agent handles the rest.

What makes it different from a database

Traditional prospecting tools are databases with a user interface: you filter, you export, you import somewhere else. Signl is built for an agent to query directly, which changes three things.

Searches run live against the market when your agent asks, so a signal like "raised a round this month" reflects this month. Every tool returns a structured result your agent can act on, including clear reasons when something is unavailable, so it never has to guess. And billing charges only for a verified contact delivered, never for a search or a miss, because an agent runs far more queries than a person would.

Getting started

Signing up is free and takes a minute, with no credit card. You start with 50 verified contacts and earn more as you set up. The fastest path is connecting your agent, then defining your ICP so results are scored for your market.

Common questions

Do I need to use the dashboard?

Only for setup and billing. The dashboard handles signing up, connecting your agent, defining your ICP, managing Loops and viewing your credit balance. The day-to-day work of finding companies and contacts happens in your AI client, not here.

Which AI clients work with Signl?

Any MCP-compatible client, which as of August 2026 includes Claude, ChatGPT, Cursor and most agent frameworks. There is also a CLI if you want scriptable access outside an agent.
