Signalbase pricing, plans and limits
Signalbase shows recruitment agencies which companies are about to hire, using funding, hiring, job-change and M&A signals with the source attached, via dashboard, API or MCP.
- Best for
- RevOps or GTM engineer building trigger-based outbound
- Not for
- Solo founder who just needs a simple contact list
Should you use Signalbase?
Signalbase gives recruiters a reason to call: a funding round, a repeated job ad or a new leader, each with its source attached. Pro is one flat monthly plan with 3 seats, the API and the MCP server included. It finds the lead and the timing; the outreach itself happens elsewhere.
Every API endpoint is independently callable as an MCP tool, so an agent can query a single funding or hiring signal without ingesting a full contact database.
The verify-before-listing pipeline and per-signal MCP pricing differentiate it from a raw data dump, but funding and hiring event data is not proprietary, and well-funded incumbents like Apollo.io and Clay can source similar signals.

Main trade-off
No public SOC 2, ISO 27001, or GDPR compliance page was found as of August 2026, which is a common procurement blocker in the sales-intelligence category.
Signalbase pricing
| Plan | Monthly price | What it includes |
|---|---|---|
| Pro | €99/mo (about $110) | 500 credits a month, 3 seats; API, MCP and webhooks included; investor data access |
| Custom | Custom | More than 3 seats or white-label: seats for the whole team, the right to redistribute signals to your own users, white-label API and webhook delivery, historical backfill and dataset licences; quoted on a demo call |
Prices are in euros on Signalbase's own pricing page (read 6 November 2026). Pro is €99 a month with 500 credits and 3 seats, and includes the API, MCP server and webhooks. Custom is quoted after a demo, for teams that need more seats or resale and white-label rights; the full list of Custom inclusions sits in the plan table. New accounts get a 7-day trial with no card required.
Before you commit
- MCP tool calls draw from the same credit pool as direct API calls, so agent-heavy workflows can burn through the Pro plan's monthly credits faster than a single human user would.
- Data Partner redistribution rights require custom negotiation above the published starting price, so the public pricing page understates cost for platforms that want to resell the data.
What Signalbase does
Signalbase watches funding, vacancies, leadership changes and deals, then returns a company profile with decision-makers and the source behind each event. The vendor claims sub-minute freshness across 7 sources. Recruiters use it to spot hiring needs before a role is advertised, and the same data is available by API, webhook or MCP.
Funding Signals
Flags new funding rounds with round type, amount, and investor names attached, sourced continuously and delivered with the original citation link.
Job Change and Hiring Signals
Tracks executive job changes and hiring patterns across more than 960,000 recorded role changes, filterable by department and seniority; hiring posts typically surface 3 to 4 weeks ahead of the matching job-board listing.
Acquisition Signals
Detects announced acquisitions and mergers in real time, returning acquirer, target, deal value, and date with the original source attached.
MCP Server for AI Agents
Exposes every signal category as an individually callable MCP tool, so an agent in Claude Code, Claude Desktop, Cursor, or Windsurf can query one signal type without ingesting a full dataset.
Show all 9 features
Verified Three-Stage Pipeline
Every signal carries an original source link and passes a three-step sourcing check before it is published, instead of being listed as raw unverified text.
REST API with Webhooks
Streams new signals into a CRM or data warehouse through webhooks or the v2 REST API, so events flow directly into an existing pipeline.
Complete Company Profiles Per Signal
Every detected event returns an enriched company profile rather than a bare event, with source attribution on the individual signal, investor data nested inside funding rounds drawn from roughly 48,000 active investors, and decision-maker data attached at company level.
List Enrichment
Point Signalbase at an existing account list, pulled from a CRM or pushed via the API, and get back live signals per account: funding, hiring, job changes, and M&A, with sources attached. Nothing is billed on a lookup that comes back empty.
Account Monitoring
Drop in a list of target companies and Signalbase maps and watches them continuously, pushing signals as they land; the documentation lists a dedicated Monitoring endpoint beside People and CSV enrichment.

Strengths and limits
Strengths
- The vendor claims sub-minute freshness across 7 sources, where exported contact databases refresh on a weekly or monthly cycle.
- The MCP server lets a coding agent call a single signal type directly, avoiding the custom glue code most sales-intelligence APIs require.
- One flat plan with 3 seats, the API, MCP server and webhooks included means a solo recruiter or small agency does not pay per seat or per integration.
- Each signal carries a source URL and a stated reason to call, so a recruiter can check the claim before dialling.
Limits
- No persistent free plan: the only no-cost option is a time-limited trial, so ongoing use requires a paid plan.
- No published SOC 2, ISO 27001, or GDPR compliance page was found as of 6 November 2026, which may slow enterprise security reviews.
- Pro's credit and seat caps are fixed; anything bigger is a quoted Custom plan.
- It finds the lead and the reason to call, but the outreach itself happens in another tool.
- Coverage depends on public and semi-public web sourcing, so very early or stealth-stage companies may not yet have a signal.

Questions about Signalbase
What does a Signalbase subscription cost?
Pro is €99 a month, billed monthly in euros, and includes 500 credits, 3 seats, the API, the MCP server and webhooks. A team that needs more seats, or the right to resell signals under its own brand, is quoted a Custom price after a demo call.
Can I use Signalbase without paying?
Not permanently. Signalbase offers a 7-day trial that asks for no card and comes with 500 credits. After that a Pro or Custom plan is needed to keep using it.
Which tools does Signalbase get compared with?
Apollo is the contact database most buyers weigh it against, and Clay is the list-enrichment option. Factors.ai covers inbound website-visitor intent. PredictLeads and Crunchbase are the closest sources of company events and funding data, one with deeper history and one updated in batches.
Is Signalbase or Apollo better for recruitment business development?
Apollo centers on a large contact database with outreach in the same product. Signalbase centers on timing: it surfaces a fresh round, a role posted three times or a newly hired leader, and shows where it read that. Pick Apollo to find and email contacts in one place; pick Signalbase if you already have an outreach routine and want the timing.
How do I get started with Signalbase?
Start the 7-day trial at trysignalbase.com, then build a search for companies that match your ideal client or drop in an account list to monitor. Developers can take an API key from the workspace API page, or connect Claude, Cursor or Windsurf through the MCP server.
About Signalbase
Signalbase is built by Signalbase B.V. in Amsterdam. It started as a signals API for sales and RevOps teams and now leads with business development for recruitment agencies: its homepage tells recruiters it shows which companies are about to hire, why now and who to contact. The product watches funding rounds, open roles, executive moves and acquisitions, attaches the original source to each event and returns a company profile with decision-makers and open roles.
Read the full background
Data reaches you in three ways. The dashboard holds saved searches for ICP-like companies and monitored account lists. The v2 REST API and signed webhooks push events into a CRM or warehouse. An MCP server lets Claude, Cursor or Windsurf query one signal type at a time. The documentation index now also lists People, CSV enrichment and Monitoring endpoints, and the vendor says each signal passes a detect, verify and normalize pipeline with an 80 percent accuracy threshold before it is listed.
In Hokai's AI SDR category it behaves more like a trigger feed than an outreach tool. Buyers weighing it usually look at Apollo for contacts, then Clay for list enrichment. Website-visitor intent is a different job, handled by Factors.ai. For raw company events the closest source is PredictLeads, with Crunchbase as the funding database. If outreach is the job, read the best AI SDRs guide first.
Who should look elsewhere: a team that wants an automated outbound agent needs a second tool, because nothing on the vendor's pages mentions email sending or sequencing. Pro is capped on credits and seats, so a larger agency, or a vendor that wants to resell the data, moves to a quoted Custom plan. Coverage rests on public and semi-public sources, and we found no SOC 2, ISO 27001 or GDPR page on 6 November 2026. It is delivered through the web dashboard and API, with no desktop or mobile app.
