Otta's take

Xav Kearney

CTO of Otta

Every day, people all over the world communicate via in-app chats. However, chat and UX tools can take months to build and years to perfect. Stream solves this problem by allowing developers to build chat and activity streams into apps quickly and without hassle.

Having started out building APIs for activity feeds, Stream quickly moved into the lucrative chat market. Its customers now include household names such as Unilever, NBC Sports, and TaskRabbit, and it has seen funding from both big-name firms and startup CEOs- a clear indication of the company's broad appeal.

The company has lately been focussed on further developing its in-house technology, in order to fuel its continued growth in the coming years. It continues to enrich its Activity Feed, Chat SDK and 2022-released AI-based Moderation products, as well as developing Live Video capabilities, which it states clients have been interested in for some time.
