We love working with clients who are themselves an industry leader with lots of data and experience in their particular space. Our newsroom is open to working with clients' first-party data but has extremely high standards for data quality, as dictated by our publishing partners and the trust they instill in us to publish work directly to their newsfeeds.
The process for validating this data and then finding stories to tell about it can take a significant period of time, so we don't often include these sorts of stories in the first ~6 months of a partnership. That said, if you have particular data you're interested in leveraging, please let us know.
In the meantime, I'd recommend we continue launching stories leveraging data from our databases so that we can start driving results and lifting performance.
