Reveal: Shine New Light on Anonymous Web Traffic

Featuresby Alex MacCaw on September 14, 2016

I'm excited to share Reveal [], a new product that delivers company data based on an IP address, effectively allowing customers to de-anonymize web traffic. Powering Reveal is a completely unique and dynamic dataset. Traditionally, IP-to-Company applications have been limited to large companies who own their IP blocks. With our new dataset however, we've also been able to effectively triangulate small private company IPs as well. Companies that until now, hav

Friday's outage

On Friday afternoon, Clearbit was down for approximately 24 minutes, from 2:14pm to 2:38pm PDT.

Accurate company categorization is a crucial part of the data we provide, and we've built up some incredible tech over this last year to automatically categorize companies by applying a neural net algorithm to their websites. This gets us the kind of coverage that would be impossible to achieve with a manual approach, and the result are impressive. Today I'd like to announce a new addition to our categorization - a high level set of tags we've dubbed super tags. While the existing tags we pro

Postmortem of yesterday's downtime

Companyby Alex MacCaw on June 10, 2016

Yesterday we had a bad outage. From 22:25 to 22:58 most of our servers were down and serving 503 errors. As is common with these scenarios the cause was cascading failures which we go into detail below. Every day we serve millions of API requests, and thousands of businesses depend on us - we deeply regret downtime of any nature, but it's also an opportunity for us to learn and make sure it doesn't happen in the future. Below is yesterday's postmortem. We've taken several steps to remove singl
