Hello Nimo! A lot of our users use both Hubspot and Clay. They use Hubspot to store their data (beginning with basic info) and use Clay to enrich the data. Do you mind elaborating a bit on the use case and I can point/ provide some more information and resources? In the meantime, I recommend checking out some of the case studies in our blog.Maybe you will find that some big companies use Clay for the same functions you have in mind.
