Problem
Generic video tools couldn't handle movement instruction or school privacy rules.
Whistle
Live classes for dance, yoga, and fitness.
The solution
Built a purpose-built streaming stack for dance, yoga, and fitness instruction during COVID lockdowns.
Approach
Selected WebRTC topology adaptively by class size instead of forcing one mode for every session
Rebuilt the audio pipeline so music was not treated as noise to cancel
Designed full-body video layouts for correction, not head-and-shoulder conference framing
Shipped a self-hosted deployment path so data never left the organization's infrastructure
Next case
Kensho
Financial research data arrived too slowly. Rebuilt the pipeline to stream market data in near real time.
