Over the course of her 4 years with the company, Underwood played a vital role inmaking Slack 's office messaging app as popular as it is today. She's widely considered to be the second-in-command to CEO and cofounder Stewart Butterfield, as her remit included much of Slack's strategy and product decisions.
After leaving Slack , she'll take a full-time role with #Angels, an organization she co-founded in 2015, that focuses on investing in female-founded companies . Tamar Yehoshua, a vice president at Google who has previously led the Search team, will replace Underwood as chief product officer.
This all comes during the walk-up to Slack's expected IPO, which could be one of the biggest public-market debuts of the year. The company was last valued at $7.13 billion after a $427 million funding round in August 2018.
"At Slack, Ive worked closely with brilliant founders to build a product that is transforming how millions of people get their work done every day," Underwood wrote in a Medium blog post announcing her move . "Looking back, I realize: I learned how to work, then I worked hard, and eventually I got the chance to help shape how millions of other people work as a product leader and executive here at Slack."
"Beyond her accomplishments in building out the product and expanding the business, April has been an exceptional leader at this company," Slack CEO Stewart Butterfield wrote in a blog post. "She has expanded and steered her team through a time of hypergrowth, and honed a high-performance-but-deeply-human culture of craftsmanship and relentless customer focus."
For its part, #Angel has invested in over 100 founders and their companies.
"Investing, which started as a side hustle for me and my #Angels partners, has emerged as the pursuit too inspiring and energizing to be relegated to my spare time," Underwood wrote.
