I use WhiteWhale to find leads who have shown actual interest in something we provide, instead of building a generic list. It gives us a simple list every day of people we can reach out to, so we don’t have to prospect manually every day. I love the founders and their customer service. They’re easygoing, quick to respond, and focused on listening to customers. The interface is easy to work with, and the integrations are really great. It’s easy to connect through an API, webhook, or MCP and send campaigns automatically to Instantly, our Claude Code, or other sequencing services. I also use it with Instantly, Heyreach, and Slack. Onboarding was super easy, and the founders were incredibly helpful. Review collected by and hosted on G2.com.

Wish they'd make it so I'd stay logged in! I haven't brought this up with them yet but I'm sure it'd be done by now if I did lol Review collected by and hosted on G2.com.
