Solsten today announced it has raised $21.8 million in its latest round of funding. The new round will go towards improving the company’s main product: An AI platform that offers insights on an audience’s psychological makeup.

Solsten’s product has three core features called Traits, Navigator, and Frequency. Traits identifies key traits in an audience via random sampling. Navigator uses info from Traits to help companies identify new audiences and marketing opportunities. Frequency is an intelligent digital asset manager that helps users predict how new material will perform with a target audience.
