How might Whoop refine its recovery score algorithm to account for more lifestyle factors beyond just sleep and strain?

Introduction

To refine Whoop's recovery score algorithm to account for more lifestyle factors beyond sleep and strain, we need to take a holistic approach that considers the multifaceted nature of human recovery. I'll outline a strategy to enhance the algorithm's accuracy and user value by incorporating additional relevant data points.

Clarifying Questions (5 mins)

• Looking at Whoop's current focus on sleep and strain, I'm thinking there might be opportunities to integrate more personalized data. Could you share insights on what types of additional user data Whoop currently collects or has access to?

Why it matters: Determines the scope of potential algorithm improvements without requiring new data collection methods. Expected answer: Whoop collects heart rate variability, resting heart rate, and some basic user-inputted data like age and gender. Impact on approach: Would focus on leveraging existing data first before proposing new data collection methods.

• Considering the competitive landscape, I'm curious about user retention challenges. What's the current user churn rate, and at what point in the user journey does most churn occur?

Why it matters: Helps identify if algorithm improvements should target early adoption or long-term engagement. Expected answer: Churn rate is around 20%, with most users dropping off after 3-6 months of use. Impact on approach: Would prioritize solutions that provide more value and insights over time to improve long-term engagement.

• Given the focus on recovery, I'm wondering about the current user satisfaction with the recovery score accuracy. Do we have any Net Promoter Score (NPS) data or user feedback specifically related to the recovery score feature?

Why it matters: Indicates the urgency and potential impact of improving the recovery score algorithm. Expected answer: NPS for the recovery score feature is 30, lower than other features, with users often reporting discrepancies between their perceived recovery and the score. Impact on approach: Would focus on improving the algorithm's accuracy and providing more transparent explanations of the score.

• Thinking about Whoop's product roadmap, I'm curious about any planned hardware upgrades or new sensors. Are there any upcoming changes that could provide new data points for the recovery algorithm?

Why it matters: Aligns our solution with future product capabilities and avoids redundant efforts. Expected answer: A new sensor for measuring blood oxygen levels is planned for the next hardware release in 6 months. Impact on approach: Would consider how to incorporate blood oxygen data into the recovery score algorithm as part of a phased approach.
