An Apollo alternative for reaching local businesses
Apollo is a large B2B contact database with sequences, a dialer and a meeting scheduler. KnockB is built for a different market: owner-run local businesses that rarely show up well in job-title databases. Here's how they compare.
Side by side
KnockB and Apollo
What Apollo does well
- A large B2B people and company database you can filter by job title, company size and more.
- Multi-step sequences that mix email, calls and LinkedIn tasks, with a built-in dialer and meeting scheduler.
- Integrations with Salesforce and HubSpot.
- An AI assistant that researches, builds lists and drafts emails.
Where KnockB is different
- Made for owner-run local businesses, like dental practices, clinics, contractors and law offices, found from open map data.
- Each email is built around one specific detail from the business's own website, and you can see the source.
- Approval first: nothing sends until you say YES, in the app, Slack or Telegram.
- Sends slowly from your own Google Workspace mailbox, in your recipients' business hours.
- No database to buy: KnockB doesn't sell or share contact lists.
