A Charlotte-based data analytics company has raised $5.9 million in a private equity offering, according to a filing with the Securities and Exchange Commission.

Stratifyd Inc. raised the money from four investors, according to the filing, and is seeking another $1.1 million from the offering.

The company previously raised $1.7 million in January 2016.

The company is a data analytics software company whose artificial intelligence platform uses machine learning to turn raw data into decisions.

For example, Stratifyd analyzed feedback from 29,925 reviews left on Cruise Critic for Royal Caribbean Cruise Lines.

It compared an older ship and a newer ship in areas such as entertainment, food, and activities to measure ratings for when the ship was first launched, three years into its voyages, and the current rating to determine which ship rated better over time.

Stratifyd said it saw 300 percent growth in 2016 through demand for its software. During the year, it added clients such as Lenovo, Kimberly Clark, and Ally Bank. Stratifyd also opened international offices in London and Beijing

Its founder and CEO is Derek Wang, who has held positions at Microsoft Research, Xerox, and Bank of America before becoming the associate director of the Charlotte Visualization Center where he worked on projects for Homeland Security and Bank of America, among others.
