Dataforge: business data enrichment. Enriches leads using public records and local AI.

In simple English

This tool finds and fills in missing business data such as emails, website technology, and company size. It works entirely on your own computer without any paid subscriptions or external accounts. You point it at a list of companies or a database, and it scrapes websites or checks public registries. It saves money if you otherwise pay expensive yearly fees for sales lead databases.

What it is

Dataforge is an open-source business data enrichment engine written in Python. It combines website scrapers, government record importers, SMTP email verifiers, and local artificial intelligence models.

What it is good for

Solo founders and small business owners who need lead generation or company research data without paying for commercial enrichment platforms.
