FullEnrich is a data enrichment tool; SalesStack is a sales engagement platform. Whether you need one, the other, or both depends on which part of the workflow you are buying for: B2B lead data and contact enrichment on one side, multi-channel sales outreach and engagement tracking on the other. This guide lays out what each vendor publishes.
The Quick Answer
FullEnrich is a data enrichment tool for B2B lead data and contact enrichment; SalesStack is a sales engagement platform for multi-channel sales outreach and engagement tracking. By each vendor's own wording, FullEnrich lists waterfall enrichment across 25+ sources and mobile phone enrichment, and SalesStack lists lead scoring and cold email outreach.
FullEnrich offers a lower entry point at $0/mo compared to SalesStack at $1970/mo.
If your priority is finding accurate contact data for target accounts, FullEnrich is the one built for it; for coordinating outreach across email, phone, and social channels, that is SalesStack. Many teams run one of each.
Understanding the Core Difference
FullEnrich is B2B contact enrichment platform returning verified work emails, personal emails and mobile phone numbers through waterfall enrichment across 25+ data sources. Available in the app, a REST API and an MCP server.
