Built around the moment they raise

Most teams hear about a raise from a newsletter. Yours hears it first.

By the time funding news is public, it's already crowded. Signl watches for the round directly, scores it against your ICP, and hands your agent a verified contact before the noise arrives.

1

Funding rounds, first

A live feed of new funding rounds, plus hiring sprees and tech adoption as supporting signals, scored against your ICP the moment it lands. Not a quarterly database dump.

2

Agent-first, not app-first

No dashboard to learn. Your agent calls four tools over MCP and composes them however the conversation demands: search, drill in, enrich, export.

3

Pay only for hits

Enrichment charges one credit only when a verified email comes back. Misses, retries, and cached repeats are free. No bounce tax.

Knowing who raised is easy. Knowing first is not.

Every option below gets you part of the way to a fresh raise. The part it skips is the part that costs you replies.

$10–30k/yr

Static B2B databases

Huge without an operator behind them.

Millions of rows, most of them stale. By the time a company shows up in the export, the funding news is old and the inbox is crowded.

$99+/mo

Enrichment credit tools

Strong on emails, blind on timing.

They'll find an address for anyone, but they can't tell you who to contact this week, and they charge you for the bounces too.

Your weekends

DIY scraping + spreadsheets

Strong on control, brutal on upkeep.

The scraper breaks, the sheet drifts, the enrichment key expires. Every hour on plumbing is an hour not spent selling.

From $199/mo

Signl

Fresh funding rounds + verified contacts, inside the agent you already use.

Ask in plain language. Get companies that just raised, with timing context and a verified decision-maker. Then export and go.

Four tools. One endpoint.

Everything below is a single MCP tool call away. Your agent picks the right one from the conversation. No UI to learn, nothing to configure per campaign.

01

search_signals

Search the live feed or run open-ended market discovery: by industry, country, headcount, tech stack, department size, or open roles. Ranked by ICP score.

  • "US startups that raised a Series A this month"
  • "UK health tech, funded in the last 30 days, under 100 people"
  • "Recently funded, now hiring their first sales lead"

get_credit_balance

Balance and plan, on demand, so your agent can budget a campaign before it starts enriching, and stop cleanly instead of failing mid-run.

{ "ok": true,
  "credit_balance": 187,
  "plan": "elite" }

Connected in four steps.

The whole setup is the length of a coffee refill. Works with Claude's native connectors and any MCP-capable agent.

Step 1

Paste one URL

Add Signl as a custom connector in Claude, or point any MCP client at the endpoint with an API key.

Step 2

Approve access

Log in, click Allow. OAuth handles the rest, with no keys pasted into config files.

Step 3

Ask in plain language

Describe the companies you want. Your agent picks the tools, runs the search, enriches the winners.

Step 4

Export & send

Verified contacts out as CSV or straight into the rest of the conversation, ready for your sequencer.
