Sarah Tavel is a General Partner at Benchmark and sits on the boards of Chainalysis, Hipcamp, Rekki, Cambly, and Medely. She is a founding member of All Raise, the nonprofit organization working to accelerate the success of women in the venture-capital and VC-backed startup ecosystem. Before Benchmark, Sarah was a partner at Greylock Partners. She joined Pinterest in 2012 as their first PM and launched their first search and recommendations features. She also led three acquisitions as she helped the company scale through a period of hypergrowth. In this episode, we discuss:

Sarah’s Hierarchy of Engagement framework for growing a consumer startup
- The three levels of the Hierarchy of Engagement: core action, retention, and self-perpetuation
- The importance of measuring cohorts and maintaining focus on the core action
- Examples of core user actions from Pinterest and YouTube
Sarah’s Hierarchy of Marketplaces framework for building a marketplace startup
- The three vectors of growth for dominating a marketplace
- Advice on “tipping the marketplace” and ultimately dominating the market
- The value of focusing on a constrained market
- How to avoid disruption

Some takeaways:

To implement the Hierarchy of Engagement framework: Start with the core action, the fundamental user engagement step. Then emphasize retention, making the product more valuable with continued use. Finally, achieve self-perpetuation through network effects and growth/re-engagement loops.
To implement the Hierarchy of Marketplaces framework: First, focus on a constrained opportunity and nail your niche. Gain saturation in that market until you reach a tipping point (you’ll know you’ve reached a tipping point when cohort retention increases and organic word of mouth is happening). Finally, dominate the market by focusing on growth within your existing market, expanding use cases, and then scaling into new markets.
Marketplace founders should first focus on users whose platform experience will be most superior to their substitute solutions. This will make early buyers and sellers stick.
Consumer social founders should ditch MAU metrics in favor of growing engaged users. When users engage with and complete the core action of the product repeatedly, it becomes more retentive for them.
