Online Directory Cuts Pageviews in Half by Blocking Bots | CrunchBase Case Study

September 1, 2015 Distil Networks

“Distil Networks’ service seemed like the stuff of magic. It has proven to be so.”

-- Kurt Freytag, Head of Product, CrunchBase


CrunchBase is the leading platform to discover innovative companies and the people behind them. It delivers market insights to millions of users and businesses around the world. The CrunchBase Dataset is constantly expanding through contributions from its community of users, investment firms, and network of global partners. CrunchBase accelerates innovation by bringing together data on companies and the people behind them.

After completing the buildout of their 2.0 site, CrunchBase noticed oddly shaped traffic, along with random spikes, all of which were putting a tremendous strain on their servers. Freytag investigated and quickly came to the conclusion that they were getting hit hard by bots crawling their site.

“We looked for what was causing the hurt on our servers and discovered that a relatively small number of entities were aggressively crawling our site in a structured pattern,” said Freytag.


  • Random spikes in bot traffic were causing brownouts
  • IT lacked visibility, tools and staff to combat sophisticated bot attacks
  • Top priority was blocking bots without impacting users or ad deliveries
  • Leadership knew content theft could disrupt long term business model
