About

What is ContactOut

ContactOut extracts verified email addresses and phone numbers from LinkedIn and GitHub profiles via a Chrome extension, and lets users search its 300M+ profile database directly from a web portal. It's built for SDRs, BDRs, and recruiters at SMB and mid-market companies who need contact data without manual research. The standout capability is its AI-assisted contact vector discovery, which surfaces personal and business emails beyond what a standard scrape would return. From there, users can build lists, run email sequences, automate follow-ups, and push contacts directly into Salesforce, HubSpot, or an ATS like Lever. Where it falls short is depth of workflow automation — teams that need a full outbound orchestration layer will find the sequencing features thin compared to dedicated sales engagement platforms.

Our verdict

Vanderbuild take

ContactOut is a focused email finder and phone enrichment tool — a solid fit for SDRs and recruiters who need verified contact data pulled directly from LinkedIn or GitHub without building a data pipeline from scratch. On the agentic side, the public API gives you enough surface area to wrap ContactOut into your own MCP layer or enrichment workflow, though MCP-native status is unconfirmed, so expect some integration work before it fits cleanly into an agent stack. Pricing starts free and the $49–$99/month tiers are accessible for small teams, but export caps and feature gating mean you'll likely upgrade sooner than expected as volume grows. The honest limitation: sequencing and outbound automation here are supplementary features, not a replacement for a dedicated sales engagement platform — use ContactOut for the data layer and pair it with something else if sequencing is central to your motion.
