## The use case: how Nielsen deploys H2O.ai

Nielsen Catalina Solutions uses H2O-3 to run analytics on a very large dataset covering US households, integrating it directly with its existing application. The data volume was too large for most analytics tools to handle.

Summary written by usedby from the source page, in English. The figures are those of H2O.ai and Nielsen, not ours.

> As the world's largest provider of TV and online behavior analytics with data on 140 million US households covering over 330 million people, the amount of data that Nielsen Catalina Solutions had to work with was too much for most analytics tools.

> H2O allowed us to interface directly with our existing application and it scales for our massive data set. There is nothing else like it.
