When Workiva (WK) had its initial public offering on the New York Stock Exchange in December 2014, Jeff Trom had been there before. The Chief Technology Officer and six members of Workiva’s founding management team took a previous company, Engineering Animation, public in the 1990s.But the second time around, the IPO was easier and less costly thanks to Workiva’s proprietary Wdesk platform, which automated the process of filing with the Securities and Exchange Commission (SEC).
