Case Studies

Kalshi built its prediction-markets app around live trading. Within months, chat became a core part of the experience. Messages grew 14x through the NBA Finals, the FIFA World Cup, and NFL opening weekend.

Rosterfy built volunteer and administrator chat with Stream, taking it from first prototype to a launch on web and mobile in about 9 months. The chat then grew to support a major global event, where about 42,000 volunteers were connected across 795 channels.

Care.com moved off a homegrown messaging stack and onto Stream, cutting bugs by up to 90% while scaling chat and video for 1M+ users.

Jay was working as a software engineer when he took the solo trip that led to Nomadtable. He intentionally stayed at hostels to meet other travelers, but found many of them quiet and unsociable. While it was frustrating in the moment, it led to an idea, why not build an app that allows travelers to connect abroad? He quit his job and gave himself a year to build it.

See how a four-person team built an AI companion app on Stream Chat, Video, and Activity Feeds, with an 11x signup lift since launch.

When PubNub overages and missing messages hit a 2,500-person workforce, MyOutDesk moved to Stream Chat in under two weeks and cut its chat code in half. Here is what happened.

Subito, Italy's largest re-commerce marketplace, moved buyer-seller messaging for 10M+ users onto Stream and now automates 99.5% of moderation, without standing up a chat infrastructure team. Here is how the build-vs-buy decision, migration, and trust and safety automation played out.

A top-5 mobile gaming publisher had six months to migrate 750M+ players off Community Sift with no drop in moderation quality across a dozen languages. Here is how the RFP, large-scale testing, on-site workshop, and shadow-testing migration to Stream AI Moderation actually played out.
