When using Ocean.io lookalikes as a source, you can input up to 10 domains as seed companies.
If your lookalike source isn't running, check that you're properly selecting the Ocean.io integration and choosing your Clay account in the setup.
Also ensure you have the appropriate columns set up when adding a source to an existing table - you may need specific column types like Company Domains for the source to work properly.
