  • CPaaS: Use proven audio SDK and audio chat capabilities from to build robust live audio conversations.
  • Subscriptions: Use of Hasura based subscriptions for managing the user states and facilitating the time sync.

"What distinguished RaftLabs from other providers was their fantastic ability to build real-time engagement-based products. We wanted to build a platform that was partly a social media channel and partly like Zoom where people could interact with each other in real-time, and they did an awesome job doing that. "
