Market Opportunity

Declared “the fastest growing app in Microsoft’s history,” Teams gained 13 million daily active users in less than two years, and is now significantly larger than Slack. Microsoft’s AppSource store features thousands of integrated ISVs, but the Teams-specific marketplace is still quite small (under 300 apps). With over 160 million Office 365 users, the search volume on AppSource is reportedly +3 million unique users per month, in part because searching and learning about apps is very easily done from within the Team UI (Desktop and Browser). And finally, AppSource facilitates app monetization (for a fee).
