Clarifying Questions (5 mins)

• Looking at the product context, I'm thinking about the scale of high-traffic events Mux currently supports. Could you provide more information on the typical concurrent viewer count for these events and the current average latency?

Why it matters: Determines the scale of the problem and sets a baseline for improvement. Expected answer: 100,000+ concurrent viewers with current latency around 10-15 seconds. Impact on approach: Would focus on scalability solutions and aggressive latency reduction techniques.

• Considering user behavior, I'm curious about the types of content being streamed. Are we primarily dealing with live sports, concerts, or interactive events like gaming?

Why it matters: Different content types have varying latency requirements and user expectations. Expected answer: Mix of content, with a growing focus on interactive gaming streams. Impact on approach: Would prioritize solutions that cater to the most latency-sensitive use cases.

• Regarding Mux's position in the market, how does our current latency compare to key competitors, and what's driving this improvement initiative?

Why it matters: Helps understand if this is a defensive move or an opportunity to leapfrog competitors. Expected answer: We're slightly behind in latency compared to top competitors, losing some key clients. Impact on approach: Would focus on both quick wins and long-term architectural improvements.

• Thinking about external factors, I'm wondering about the geographical distribution of Mux's user base. Are we dealing with a global audience or primarily focused on specific regions?

Why it matters: Influences decisions on CDN strategy and server placement. Expected answer: Global audience with concentrations in North America, Europe, and Asia. Impact on approach: Would consider a multi-region approach with optimized routing.
