Business contacts and direct dials, indexed from public web sources — company sites, business registries, and public filings. Around 70% aren't on Apollo, ZoomInfo, or any other prospecting platform, and every record links to the page we found it on.

Run a free coverage checkNo need to switch tools. Run DataSigma alongside whatever you use today — upload the domains you already have contacts for and exclude them, so every search surfaces only the contacts you're missing.
Based on our most recent sampled overlap test against major prospecting platforms.
Other vendors ask you to trust a black box. We show our work — every record links to the exact public page where we found it. Click the source, check it yourself. That's the difference between a resold list and an index we built ourselves.
From public web sources to your pipeline, in three steps.
We continuously index publicly accessible web sources — company websites, business registries, public directories, and regulatory filings — processing billions of pages each month. We respect robots directives and publisher access controls.
Our models read each page the way a person would — identifying names, roles, business emails, and direct dials that simple pattern-matching extractors miss.
Every contact is validated and linked to its source page before it enters the index. No recycled lists, no purchased databases.
Owners and founders who never made a LinkedIn profile. They run real businesses — they're just not on the network every other vendor draws from.
Deliver coverage your client's competitors can't buy. Exclusive data is a deliverable, not a commodity.
Waterfall us after your primary vendor. We match the domains that came back empty.
A small list of untouched contacts beats a big list of exhausted ones.
Publicly accessible web sources: company websites, business registries, public directories, and regulatory filings. We index these sources ourselves, extract contact details with our own AI models, validate them, and attach the source URL to every record. Nothing is purchased, resold from another vendor, or taken from LinkedIn.
Those platforms largely share one upstream: LinkedIn-derived data. Our index is built independently, so about 70% of our contacts appear on no other prospecting platform. We work well alongside them — we cover what they miss.
Every email is verified before it enters the index, and you can re-verify at export. Where a contact can't be verified, we say so instead of selling it anyway.
Every contact links to the public page where we found it. Click it and see for yourself — no black box.
Yes — that's the coverage check. Upload your unmatched list and we'll show you how many we cover before you spend a credit.
We hold business contact data only — names, roles, business emails, and business phone numbers indexed from publicly accessible sources. We do not hold consumer, financial, or special-category data. For B2B business-contact data we rely on legitimate interest as our lawful basis under the GDPR, we provide the notice required by Article 14, and every record carries the URL of the public page it came from. Opt-out and erasure requests are honoured and processed within 30 days via our Privacy Center. Full details are in our privacy policy.
