Goodwin Procter is poised to pocket $2.5 million for its work on San Francisco-based Slack Technologies, Inc.’s initial public offering, according to its updated S-1 filing with the U.S. Securities and Exchange Commission ahead of its debut on the New York Stock Exchange.

Stock prices in Slack opened at $38.50 a share, up from a reference price set at $26 on Wednesday, valuing the company at over $20 billion.

The workplace messaging company made its debut through a direct listing on the New York Stock Exchange, rather than through a traditional public offering.

Goodwin is Slack’s principal legal advisor on the IPO, while Latham & Watkins is representing its financial and associate financial advisors. Allen & Co., Goldman Sachs Group Inc., and Morgan Stanley advised on the listing.

Leading the team for Goodwin is capital markets partner Richard Kline.

Kline joined the firm from Wilson Sonsini Goodrich & Rosati in 2011 and since then has been the lead adviser on some of the most recent high-profile IPOs in the startup community. Kline and his team represented JP Morgan as an underwriter in Lyft Inc.’s $2.6 billion IPO in March and Goldman Sachs and Morgan Stanley in Snap Inc.’s $3.4 billion IPO in 2017.

Goodwin partner David Van Horne and associate Sarah Axtell also advised Slack on its IPO.

Corporate partners Gregory Rodgers and Benjamin Cohen led the team at Latham which also included three associates.

It’s a busy season for tech IPOs and many Big Law firms have gotten in the action. Goodwin and Wilson Sonsini both worked on Lyft’s public debut. Uber Technologies Inc.'s IPO, one of the most anticipated offerings in years was completed with the helpof Cooley, Covington & Burling, and Davis, Polk & Wardwell.
