Fresh, reliable B2B 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 billions of data points, we create marketing intelligence from a variety of sources, including social profiles, company websites, legal filings, crowdsourcing, plus many more.


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 analyze billions of data points every day and turn them into standardized and usable attributes. Role, Seniority, Company Tags, Estimated Revenue, Location, Technologies, and much more.


How accurate is the data?

At Clearbit, every record goes through four stages of verification. First, has the record been refreshed within the last 30 days? Second, do the data sources for the record agree with one another? Third, are there anomalies, and if so, why? Finally, does the data look accurate to our highly trained team of researchers? This process ensures that each record is as accurate as possible.

Data Stats


From day one, we have striven to have the freshest, most accurate data in B2B. Over the past six years, continuous improvements to our data set and machine learning algorithms have positioned Clearbit as the proven industry leader in data quality. Our data and solutions now power the world's fastest growing B2B companies.

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 Days or weeks later, things have changed and a percentage of that dataset is no longer valid.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 rebuild every single record every 30 days to ensure that you have the most up-to-date data possible.
