Audience Owl
Audience Owl was a data enrichment tool, started in late 2014 to make data enrichment accessible to everybody.
Audience Owl is no longer active. It has been shut down, and the service, accounts and data are no longer available. It was succeeded by mailfloss, an email list hygiene and verification service.
Thanks to everyone who used it and sent feedback along the way.
Audience Owl was a project by Marty Wong. See what he’s working on now at martywong.com.
