John “Jack” Sheridan, a former co-managing partner of Wilson Sonsini Goodrich & Rosati, has joined Latham & Watkins as a corporate partner in the firm’s emerging companies practice.

Sheridan, who joined Wilson Sonsini straight out of law school in 1986, has worked on some of Silicon Valley’s most iconic deals. He represented YouTube from its initial financing through its $1.65 billion acquisition by Google Inc. in 2006, as well as French enterprise software company Business Objects SA on its $7 billion sale to German software giant SAP AG the following year.

Sheridan has also represented companies and underwriters in more than 100 initial public offerings and advised more than 150 companies in venture capital fundraising. In 2012, he became co-managing partner of Wilson Sonsini along with Douglas Clark, who remains at the firm as its sole managing partner. Sheridan said he wasn’t looking to leave his Wilson Sonsini before Latham approached him.

“Latham has tremendous and deep capabilities both in the U.S. market and internationally,” he said. “They’re just broader and deeper in scope than most any other firm in the world. They have built something that’s going to be very difficult for other firms that haven’t built it to replicate.”

Latham grew across all financial metrics in 2016, pulling in $2.823 billion in revenue, the highest figure ever generated by a law firm in a single fiscal year. Latham’s profits per partner climbed 5.3 percent, to $3.06 million. Wilson Sonsini had a more mixed year financially, with gross revenue up 2.7 percent, to $755 million, and profits per partner down 11 percent, to $1.97 million.

Sheridan’s arrival at Latham comes four months after former Cooley partner Christopher Shoff joined the firm’s emerging companies group in Century City, California. In April, Latham hired emerging companies partner David Concannon from Orrick, Herrington & Sutcliffe in New York.

Tad Freese, managing partner of Latham’s office in Menlo Park, California, said that bringing in Sheridan was part of the firm’s continuing effort to grow its technology practice.

“Jack is such a well-known player in the Bay Area that I think regardless of strategy we would have been excited to talk to him,” Freese said. “He’s really grown up here. I think he’ll do wonderfully on our platform.”
