We index the part of the market
everyone else skips.

Datasigma builds B2B contact data from public web sources — not by reselling the same lists everyone already has, but by indexing, extracting, and verifying contacts at the source.

Why we exist

Every prospecting tool sells the same list.

Most B2B databases are built the same way: draw from LinkedIn, license the same aggregators, resell the overlap. The result is an entire industry working the same few million contacts — records that have been in everyone's pipeline for years.

The open web tells a different story. Company team pages, registries, directories, and public filings mention tens of millions of decision-makers who never appear on any prospecting platform — owners, managing directors, and operators across every market and language.

So we built an index of them. We continuously index billions of publicly accessible pages a month — company websites, business registries, public directories, and regulatory filings — use AI to read and extract contact details in context, and verify every email before it enters the index. And because we found each contact on a real public page, every record links to the source URL where it was found — a receipt you can check yourself.

What we stand for

Transparency

No black boxes. Every contact carries a citation to the public page where we found it, so you can verify the data before you ever reach out.

Quality over volume

Every email is verified before it enters the database and validated again in real time when you reveal it. If we can't deliver usable data, you don't pay.

Responsible data

We index publicly available business information only, honor removal requests, and hold ourselves to responsible-use standards across every market we cover.
