    The complete in-app collaboration API and SDK. Add contextual activity feeds, chat, and document collaboration directly into your apps to increase user engagement, improve in-app retention, and reduce customer churn. Modern apps need advanced collaboration features. Period. And let’s face it — a lot of app developers struggle to prioritize building their core functionality versus adding the contextual collaboration features that keep users engaged and productive. The big B2B tech players are already acquiring or building out chat, secure file sharing, contextual activity feeds and threaded conversations functions, which means every app is going to need them to stay competitive. That’s where Weavy comes in.
