FORTUNE — Vox Media, the fast-growing publisher of content sites like The Verge (tech) and SB Nation (sports) disclosed today in a regulatory filing that it has secured $34 million of a new $40 million funding round.

Fortune has since learned that the Washington, D.C.-based company plans to close on the full $40 million shortly (“a timing issue,” according to a source) and that the round was led by Accel Growth Fund.

Accel Partners was an existing Vox investor via its early-stage funds, and was joined on the new deal by fellow return backers Khosla Ventures and Comcast Ventures.

Vox previously raised around $40 million, including a $17 million round last year. The company is known for pursuing “premium” audience (i.e., well-education, relatively wealthy), rather than focusing on a high-volume audience model.
