About

What is LimeLeads

LimeLeads pulls contact and company data from public sources, runs it through AI-powered verification weekly, and surfaces emails and mobile numbers for US-based B2B contacts. It's built for SDRs, BDRs, account executives, and founders at SMBs and mid-market companies who need to build targeted outreach lists without a research team. The standout capability is triple-verified contact data with credit refunds issued automatically when a contact turns out to be invalid — a concrete accountability mechanism most databases skip. Filters cover location, industry, company size, and job title, and lists export cleanly to CSV or Excel. The main limitation is geography: the database is US-only, so teams prospecting into EMEA or APAC markets will need a separate data source.

Our verdict

Vanderbuild take

LimeLeads is a straightforward US B2B prospecting database — no frills, no CRM bells — and for SDRs, AEs, and founders who just need accurate emails and mobile numbers to start outbound, it does that job without a lot of setup overhead. On the agentic readiness front, there's no API and no MCP server, which means you can't drive this from an AI agent or plug it into an orchestration layer without scraping the UI — a real ceiling if you're building any kind of automated enrichment workflow. Pricing is affordable for small teams at $499/month for 2,000 leads, but the per-credit overage model means costs can climb quickly once you're running high-volume sequences. The database is US-only, so if your ICP spans international markets, you'll be stitching together a second data source from day one.
