Datanyze is a big data sales intelligence startup that checks millions of websites to see which SaaS software companies are used and find the best look-alike leads. “It turns out that one of the best predictive attributes for lead quality is based on the tech stack of the new prospects,” CEO Ilya Semin told me yesterday. “For example, if you’re an enterprise solution and you see that a prospect is using WordPress, Google Analytics, and GoDaddy … there’s not a big chance they’ll sign up. But if they’re using Marketo, Salesforce, and Akamai, they clearly have a budget.”
