AI Summary

Open-source CLI and library that sequences multiple third-party data providers to cheaply enrich contact details like emails and LinkedIn URLs from names and companies.

How It Works

🔍 Discover the tool

You hear about this smart, free tool that finds people's work emails, LinkedIn profiles, job titles, and more for a fraction of the usual cost.

📝 Sign up for data helpers

You quickly create free accounts with a few trusted data services that provide contact info.

3
🔗 Connect your accounts

You link those service accounts to the tool so it can pull info from them smartly.

You type in a name and company, hit go, and instantly see their email, profile, and details appear with a low cost and high confidence score.

5
📊 Process a list of leads

You upload a spreadsheet of names and companies, set it to run, and it fills in missing info for hundreds at once.

6
💾 Review and save results

You check the enriched spreadsheet with new columns for emails, profiles, costs, and sources, all validated for accuracy.

🎉 Save big on leads

Now you have verified contacts ready for outreach, paying pennies per lead instead of dollars, just like fancy paid services but open and yours.

What is enrichment-kit?

Enrichment-kit is a TypeScript CLI and SDK that enriches leads with emails, LinkedIn profiles, titles, and phones using a waterfall of providers like Hunter, Apollo, and Proxycurl. You bring your own API keys, run cheap vendors first, and short-circuit on hits to slash costs by 85% per lead compared to Clay.com. Fire it up with `npx enrichment-kit enrich --name "Brian Chesky" --company "Airbnb"` for instant results, or batch-process CSVs.

Why is it gaining traction?

As an open-source Clay.com alternative, it delivers the same waterfall smarts—auto-sorting providers by effective cost—without SaaS markups or sales calls. Built-in cache, semantic validation to block junk data, and free-tier key support make enrichment dirt cheap and reliable. Devs love the self-hosted GitHub tool that embeds anywhere via SDK, with full TypeScript types.

Who should use this?

Sales ops building lead gen pipelines from name/company lists. Indie hackers scrubbing 10k-row CSVs for outreach. Backend devs adding contact enrichment to CRMs or automation workflows without vendor lock-in.

Verdict

Grab it if you need a dev-first, open-source enrichment kit today—solid docs, CLI batching, and MIT license make it production-ready for side projects. With 14 stars and 1.0% credibility, it's early-stage; watch for more providers before scaling to enterprise volumes.
