Who we power

One infrastructure. Three structural problems solved.

Every platform we work with suffers from the same weakness: data decay. We are the change-detection layer that fixes it.

AGENTIC AI GTM PLATFORMS

The freshness engine behind their intelligence

AI products without fresh data are hallucinating SDR. Without real-time signals, agents recommend dead accounts, miss funding rounds, nd target stale leads. We are real-time signal layer that keeps AI credible.

LARGE DATA PROVIDERS

The real-time refresh on top of static databases

Volume of data does not guarantee results. Skip the human validation with our source links and confidence scoring per signal.

CRM & TAM MAPPING PLATFORMS

The infrastructure that keeps their market view alive

Integrating signal layer on top of your datasets should not be a hustle. Get your signal-based API running in seconds.

Find the gaps
within your existing data

Signalbase sits between raw sources and your product. We detect, verify, normalize, and deliver real-time signals so you don't have to build the pipeline yourself.

1

Detect

Monitor thousands of sources continuously for real-world changes.

2

Verify

Source links and confidence scoring on every signal.

3

Normalize

Clean, consistent schema across all signal types.

4

Deliver

API and webhooks for production use. Real-time.

Most platforms underestimate what it takes to ship real-time signals

Scraping is the easy part. The system is the work. Most teams underestimate the ongoing cost of monitoring, verifying, and maintaining signal pipelines at production scale.

1
Monitoring sources continuously
2
Verification + deduplication
3
Backfills + uptime guarantees
4
Edge cases + schema drift
5
Maintenance forever

Signalbase gives you the system — not just the data.

The first Signalbase workflow is already working. We pulled 332 companies fast, and the quality is unreal. I'm still building the workflow, but I already know this is going to deliver big results

Signalbase is significantly cheaper, more reliable, and accurate than trying to build your own funding workflows in tools like Clay - it saves us hours and hours of time and is the best solution out there

Signalbase has been instrumental in helping us reach companies in buying situations with pinpoint accuracy. And then automate it with their easy and comprehensive APIs.

After exhausting every major data provider, few met our hygiene standards. We're proud to be able to build on your intent, funding, and M&A data!

Wow Georgi. I just recreated my M&A search in like three minutes. Deal announcement date was just sitting there already in the list, didn't have to run enrichments for it.

We were able to pull highly targeted M&A lists and look for funded companies in no time. The export quality has been rock solid, much more reliable for our current M&A workflows. Devs hasn’t raised a single concern about data quality.
