WhiteWhale

WhiteWhale is a custom buying signal platform for outbound sales teams. Users write up to 35 custom signal questions matching their sales motion, such as hiring a new sales leader or posting multiple SDR roles, and the platform monitors accounts for those signals across news, hiring, public filings, and more. Each signal is presented with sources and quotes. Accounts can be delivered to Slack, HubSpot, Salesforce, or other workflows via integrations, an API, or webhooks, and users can receive email alerts when activity occurs at followed accounts. The page lists plans starting at $200/mo for 300 accounts monitored weekly and $500/mo for 750 accounts monitored weekly, with unlimited seats and integrations included, and offers a free signal preview with no credit card required.
