Overview
About Datasigma
Datasigma indexes business contacts from public web sources such as company websites, news, directories and registries, and focuses on SMB owners that larger databases miss. Records include verified emails and their source, with exclusion of contacts you already have and access via API and MCP.
What it does
Datasigma lets users search contacts by industry, location, company size and owner role, validates emails in real time and re-verifies them at export. Users can upload existing contact or domain lists to exclude matches, so credits are spent only on net-new contacts. Data can be exported to existing tools or accessed through an API and a Model Context Protocol server for AI assistants such as Claude, ChatGPT and Perplexity.
Where it fits
It sits at the top of the outbound sales stack, supplying contacts to a CRM or sequencing tool, and can be used to refresh and enrich existing CRM records.
Who it suits
Sales teams, agencies and founders prospecting small and medium-sized businesses, plus developers building enrichment into their own tools.
