Fresh, reliable business data

Having instant access to the data you need can feel like magic, but behind the curtain, Clearbit is using today's smartest technology to find that data for you.


Where does the data come from?

Combining over 250 public and private data sources and sorting through millions of data points, we provide business intelligence from a variety of sources: social presence, company websites, legal filings, crowdsourcing, and many more. We source all of our own data and don’t rely on any of the traditional downstream data providers.

250+ data sources


How is that turned into useful data?

Not all data is equal, and all those data points can create a lot of noise. By dynamically weighting and scoring each data source in real time, we are able to make smart decisions about which data source to use for each attribute. We also use machine learning to analyze the data and turn it into standardized and usable attributes. Role, Seniority, Company Tags, Estimated Revenue, etc.

55+ company attributes

40+ person attributes


How accurate is the data?

At Clearbit, every record goes through two stages of verification. First, is the data fresh and has the record been refreshed within the last 30 days? Second, is the data correct? Unfortunately, not all publicly available data is accurate, and we use a combination of outlier recognition and a highly trained QA team to ensure that every single record is as accurate as possible.

Data Stats


From day one, we have striven to have the best data accuracy in the business. Over the past two years, our data set and machine learning algorithms have improved to the point where we have the best data in the business, and we’ll prove it. Just get in touch, and we’ll happily run a heads up data test with you.

94% Email deliverability


Companies and contacts are constantly changing. At any given moment, a dataset, even the very best one, has a finite lifespan. Days or weeks later, things have changed and a percentage of that dataset is no longer valid. To combat this, we proactively re-build every single record every 30 days to ensure that you have the most up-to-date data possible.
