Sendbird is the leading in-app chat, voice, and video API for market leaders who connect and engage tens of millions of users every day. Sendbird is trusted by global brands such as Reddit, Hinge, Paytm, Delivery Hero, and Teladoc.
Stream started as an activity feed API servicing customers such as CNBC Sports and Crunchbase. Stream then added a new chat offering which for the most part targeted smaller-scale startups and SMBs, with some recent exceptions.
The apps that hundreds of millions of users rely on every day are built on Sendbird.
