Unlock value for your customers with the most precise website identity resolution API built right into your app
Seamlessly identify anonymous visitors and enrich your customer data with the best visitor identification data on the market.
Integrating with Customers.ai was a breeze, and the data accuracy has been incredible. It’s added huge value to our existing 5,000 customers. We initially considered building it ourselves, but quickly realized it would have taken an entire engineering team and years of work. With Customers.ai, we were up and running in just two weeks!

Poor data quality from other identity resolution providers is sabotaging your app’s success
Meet the worst-kept secret in the identity resolution space – bad data.
In testing by U.S. ecommerce brands, popular identity resolution vendors showed 5-30% accuracy rates.
That data you are paying for? Almost entirely incorrect, reflecting poorly on any app that OEMs that data and causing customer churn.
Customers.ai was shown to have a 65-85% data accuracy rate, ensuring your customers are getting the right contact information, as well as a 2-18x higher True Match Rate!

What can you do with the Customers.ai API?
Website Personalization
CDPs and personalization already work on “logged in” users. That’s only a small percentage of your traffic. The Customers.ai API extends that to non-customers and anonymous visitors you can’t identify.
Marketing & Sales Outreach
If you’re a landing page technology or a website pop-up solution capturing first-party data, Customers.ai can help you re-identify those existing customers that might get missed.
Restore Remarketing
Restore website remarketing use cases and enable new ad analytics use cases with enriched anonymous visitor data.
How Customers.ai Guarantees Data Accuracy and Trust
To help you feel confident in our data, we analyze our data quality using your customer websites as the testing ground.

Consumer & B2B Data Enrichment API
What makes the Customers.ai API so powerful is it goes beyond basic visitor identification.
Our consumer data network allows us to enrich and append data on contacts we provide or enrich the contacts you are hosting on behalf of your companies. This data includes business and employment information and is updated monthly.
Name, email, or phone can be used to query the database to retrieve a match with the additional fields.
Customers.ai is the only visitor ID solution with a true API endpoint
Other ID resolution applications are monolithic desktop apps that provide the ability to send data via a webhook.
Our API lets developers programmatically manage accounts and sub-accounts, monitor utilization, and more — with full flexibility and control.


100% privacy law compliant technology
We safely and securely encrypt visitor data before sending to any platforms, ensuring data is safe and eliminating any privacy issues.
