LeadMine
Find B2B leads and emails fast
What is LeadMine
LeadMine lets you search a database of 200M+ contacts by job title, industry, company, and location, pull verified business email addresses, and export the results to CSV or Excel. It's built for SDRs, BDRs, and founders at SMBs and mid-market companies who need a straightforward way to build a prospect list without a heavy procurement process. The Chrome extension stands out for on-site lead capture — you can grab contact data while browsing a company's website or LinkedIn profile without leaving the page. Data is updated daily, which keeps bounce rates lower than static list tools. That said, LeadMine doesn't offer native CRM integrations or sequencing, so it stops at the list-building stage — you'll need a separate tool to run outreach.

Vanderbuild take
LeadMine is a no-frills email finder and prospecting database that does one thing clearly: get you a verified contact list fast, which makes it a practical starting point for SDRs and founders who don't need a full sales engagement platform yet. On the agentic side, the API exists and is documented, but agentic readiness is limited — you can wire it into a basic enrichment workflow, but you'll hit walls before building anything sophisticated on top of it. Pricing is freemium with a credit-based model, so it's affordable to test at small volume, though costs will climb as your prospecting cadence scales. The honest gap is integrations: there are no native CRM or sequencing connections mentioned, meaning every workflow requires a manual export step or a custom API build to move data downstream.
