Soundcloud has 125M MAU and switched to Stream after 3 inhouse versions of activity feed tech. Inhouse solutions struggled with firefighting and were expensive to run. The engineers who created the inhouse solutions were no longer at Soundcloud. Stream enabled Soundcloud to focus their engineering on what makes the app unique. Scaling has never been easier and Stream is more afordable than inhouse.

For years eToro relied on their inhouse activity feed tech. Switching to Stream improved performance and gave them access to ranked feeds. The activity feed now runs faster and is more cost effective than an in house solution. More importantly, conversion improved by 300% due to the ranked feeds and performance improvements.
