Atrium has been quietly building intrigue across both the technology and the legal community. The mystery project, championed by Twitch founder and Silicon Valley serial entrepreneur Justin Kan, announced in April that it would be raising $10 million in venture capital funding to “disrupt the legal industry,” a pronouncement that tends to raise eyebrows and produce very little actual disruption.

The company finally launched publicly this week as both a new law firm and a software company, two separate entities under the same roof. Atrium LTS, the venture-backed software side, will be charged with designing and deploying software for the law firm to use. Atrium LLP, the law firm, will offer flat fee services to the startup community via two specific services: Atrium Counsel and Atrium Financing.
