B2B contact and company database with built-in email sequencing, calling and a Chrome extension.
For small teams that want contact data and email sequencing in one tool. Whether it fits depends on how well the database covers your ICP, so test a few hundred records from your own target list before you commit. Verify emails with a separate tool before anything sends.
Spreadsheet-style list building and enrichment across 150+ data providers, with Claygent AI research agents and support for your own API keys.
For GTM engineers and ops teams who build outbound lists from several data sources at once. It fits if someone will design and maintain the tables, since the value sits in the workflow you build. Bring your own API keys where Clay supports them to keep data credit use down.
