Slack has kicked off 2016 by promoting head of platform April Underwood to VP of product.
Slack CEO Stewart Butterfield told Techcrunch: "April made a huge impact as Head of Platform. We’re excited to see that influence expand as she takes on a larger role."
Before joining the popular business messaging app, Underwood was at Twitter, where she worked on a variety of high profile products, including being the product manager of the first Tweet and Follow buttons.
She was also the director of the business development team. She left in June as director of product, after nearly five years at the social media giant.
At Slack, she has led in building an ecosystem for developers, including the launch of an $80m development fund in December, which is seen as giving the firm a serious advantage over competitors.
Away from Slack, Underwood was one of the founders of the #Angels fund.
Slack had 20,000 users when it publicly launched in September 2013, and had over 2 million active users by December 2015. Butterfield said that on average users spend 10 hours a day connected to the service i.e. their working day, and are actively using it for 2 hours a day.
The firm has been eyeing a potential $2bn valuation.
