GTM data enrichment tools
Add useful company and contact information to your sales workflow. Explore tools for research, connecting data sources and turning incomplete records into something your team can use.
How we review tools
We look at the job a tool does, how it connects to a sales process, its costs and its limits. “Used by H2” means it is part of our work. “Researched by H2” means our notes are based on research rather than hands-on use. Each tool has a dated review with the full context.
“Best” means best for the job described. Check a small sample from your own market before committing to a larger plan. Our current focus is B2B outbound; teams running paid advertising or product-led growth will need a different mix.
H2 is a Clay Solutions Partner and a Smartlead Certified Partner. Each tool shows when its pricing and notes were reviewed. Check the linked vendor pages for current billing terms.
