About

What is Outsell

Outsell is a Chrome extension that pulls B2B contact data while you browse LinkedIn or work inside Salesforce, putting phone numbers and emails in front of you without leaving your workflow. It's built for SDRs, BDRs, and Account Executives at solo operations and small teams who need contact data but can't justify a five-figure data subscription. The standout detail is the price: Outsell is entirely free, with no tiered credits or paywalled exports — a meaningful difference from most prospecting databases. That said, the tool is browser-bound and UI-only, so if your stack relies on API-driven enrichment or automated data pipelines, Outsell won't fit that architecture.

Our verdict

Vanderbuild take

Outsell is a no-cost entry point into the email finder and prospecting database category — a reasonable first tool for early-stage SDRs and AEs who need contact data without committing budget. On the agentic readiness front, there's no API and no MCP server, which means you can't drive this from an agent or plug it into an automated enrichment workflow without scraping — it's strictly UI-only. Free or near-free, so the risk to test is essentially zero. The honest limitation is scope: Outsell works well as a point-of-research tool inside LinkedIn and Salesforce, but teams that need bulk exports, enrichment at scale, or programmatic data access will outgrow it quickly.
