Ep118 – Cal Henderson (Co-founder & CTO – Slack) on pivots, product & the future

My guest for Episode 118 of The Startup Playbook Podcast was the Co-founder & CTO of Slack, Cal Henderson.

Cal has co-founded two successful startups, with his co-founder Stewart Butterfield, from the ashes of failed video games.

Initially, he co-founded photo sharing application Flickr which was acquired by Yahoo! Today he’s Co-founder and CTO of Slack and looks after the technology behind the growing platform.

Slack is a team collaboration and communication tool that publicly listed on NYSE in 2019 and has a market cap of $18B (as of June 2020).

In this interview we discussed:

  • Managing failure and pivots
  • The challenges and opportunities of building out new categories
  • Dealing with competitors like Microsoft
  • Responsibility of products like Slack in how their products are used
  • What the future of work may look like in a post COVID world
  • & much more
