Enterprise Knowledge Graph startup Stardog Union has increased their series A funding to $9 million, by adding $3 million from the New York City-based venture capital firm Tenfore Holdings. 

“We’re thrilled to have Tenfore Holdings as a new partner,” said Stardog CEO and cofounder Kendall Clark in a statement. “Our Knowledge Graph Platform has the potential to transform the way enterprises manage their data. Tenfore’s experience, both as investors and operators, and their network will be invaluable in helping us get there.”

The funds will be used on marketing, sales and speeding up product development for the Crystal City–based firm. The other $6 million was led by DC’s Grotech Ventures, with participation from Core Capital and Boulder Ventures. 

“Other solutions today cater to a slice of the enterprise data landscape. Stardog’s pace of growth is exciting, and Tenfore is pleased to back this exceptional team,” said Dan Levine, managing member of Tenfore Holdings in a statement.

“All of your readers are super familiar with knowledge graphs and use them every day, because what Facebook, Google and LinkedIn are based on monetizing very large datasets, and use knowledge graph information to manage those datasets,” Clark told Technical.ly DC. “It’s a technique for managing large scale datasets, so we provide software for companies to manage their internal data sets using many of the same approaches and techniques that Google and LinkedIn and Facebook use to manage their data.”
