A Clay alternative for agencies that sell to local businesses
Clay is a powerful toolkit for building your own data and outreach workflows. KnockB is a finished workflow for one job: finding local businesses, researching each one, and writing personal emails you approve. Here's an honest look at both.
Side by side
KnockB and Clay
What Clay does well
- Spreadsheet-style tables connected to 150+ data providers, with waterfall enrichment across them.
- Claygent, an AI agent that researches companies and people on the web.
- Flexible workflows you design yourself, from signals to sequences, with CRM sync to HubSpot and Salesforce.
- Local company search from Google Maps listings.
Where KnockB is different
- Nothing to build. You describe who you sell to; the agents plan, find, research, score and write.
- Built around owner-run local businesses: discovery from open map data and signals read from each business's own website.
- Research you can watch: every page an agent read, and the source behind the detail in each email.
- Approval first: every email waits for your YES in the app, Slack or Telegram.
- Sends a few emails a day from your own Google Workspace mailbox, rather than from new inboxes and domains set up for outreach.
