90 minutes of unfiltered product advice from Snap and Discord’s product chief | Peter Sellis

Lenny's Podcast: Product | Career | Growth | Sep 20 2026 | 01:36:53

Peter Sellis was the first product manager at Snapchat, where he spent seven years building one of the most beloved consumer products in history. He went on to serve as Head of Product at Discord, where he helped drive some of the fastest user growth the platform had seen. Having left his role at Discord, he gets to be especially real and unfiltered — nothing to promote, no PR, no comms team.

In our in-depth conversation, we discuss:

1. Why Peter designs teams like . . . terrorist organizations

2. What it was really like to manage Nikita Bier

3. Why the median PM is so bad

4. Why Snapchat’s ads business never reached its potential

5. Why growth almost always comes from the core product

6. Peter’s three “oxymorons” of great product management
