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

Peter Sellis, the first PM at Snapchat and later Head of Product at Discord, speaks candidly without a PR team about how he has built and led product organizations. The conversation covers team design, the quality of the average PM, Snap's monetization challenges, growth tactics, ads and AI, and his own product heuristics.

01Key learnings

• Collaboration carries hidden coordination costs that slow teams down to the pace of the slowest node; a clear ideology plus clear decision rights can reduce the need for it, according to Sellis.
• Give product leaders explicit, repeatable phrases that shortcut the company strategy, and tie them to both a mission and concrete metrics so teams can act on them.
• Growth often comes from deepening engagement with your core users (higher daily or weekly use) rather than chasing new monthly users; Sellis credits performance work and focus on existing users for Snap and Discord growth.
• Define 'core product value' as a short phrase broken into measurable components, then use it in onboarding and roadmap prioritization so every feature is checked against it.
• Ads businesses reward long-term thinking: driving advertiser ROI today drives revenue tomorrow, so avoid short-term price cuts that hurt long-term value.
• Build the ability to say no; restraint in what not to ship is a core taste skill, and interviewing candidates about ideas they chose not to ship reveals it.
• Systems thinking becomes practical when you model the system in a spreadsheet: map stocks, flows, levers and distributions instead of only asking 'why' five times.
• Push the best people with more responsibility and defend them publicly, while recognizing that a quiet manager is not necessarily a failing one; strong PMs also balance confidence with humility and structure with comfort in ambiguity.
