After leading a team spread around the globe to build popular task management tool Todoist, he set out to build Twist, a tool specifically built for conversations that deserve a longer shelf life.I chatted with Amir last week to hear his thoughts on the strengths and weaknesses of both approaches, how he balances the two (and handles emergencies) and why he has focused heavily on making async a part of his company’s culture.
