Wilson Sonsini Goodrich & Rosati is broadening its commitment to digitizing legal services with a new application, developed with software as a service company Workiva, that helps automate the registration statement required for initial public offerings.

The firm, which has advised more U.S. technology companies on IPOs than any of its rivals, is tackling the document known as SEC Form S-1 with an app it's calling WS-1. Wilson Sonsini turned to Workiva because of the company's existing expertise in transforming the IPO process and clients' familiarity with its work and brand.

"Workiva is one of the companies out there that was truly focused on digitalizing the disclosure process," said Wilson Sonsini chief innovation officer David Wang. "They had a platform, but no legal-specific content per se."
