Bloomberry tracks when companies start or stop paying for more than 1,700 B2B products, reading infrastructure signals such as DNS records, subdomains and certificate logs rather than only website tags or job posts. Sales and marketing teams use it to find accounts that just bought in their category, recently churned from a competitor, or are nearing renewal, and get alerts by email or Slack. The same data is available through a REST API for sales platforms and enrichment tools.
