Business Objectives

Founders were driven by the vision to build a decentralized, robust, and intuitive audio platform that allows decision-making for thousands of people. The goal was to build a highly responsive web application that anyone can use in few easy clicks to leave their view on critical decision-making, engage in live anonymous conversations, and vote for impactful ideas.

Ease of use
No plugins and no apps. Just go to web and start talking. As simple as that.

Voice (Audio) Communication
To build an easy-to-use and engaging web based app system for all user age groups.
Mobile phones that previews the application to show that it works on smaller screens too.
Web Experience
Capture audio inputs at scale. Build scalable audio breakout rooms where users can talk using their phone.

Project Development Considerations

With our experience in live audio and video communications, we identified the following critical aspects of the system.

Scale: Building a scalable microservices architecture using serverless AWS lambda.

CPaaS: Use proven audio SDK and audio chat capabilities from Agora.io to build robust live audio conversations.

Subscriptions: Use of Hasura based subscriptions for managing the user states and facilitating the time sync.

  • Time-bound discussions and voting for thousands of users in parallel
  • Voting and intelligent idea routing 
  • Anonymous real-time audio chats and conversations 
  • Audio recordings and live discussions views for the admin

"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. "
