Peter Deng has led product teams at OpenAI, Instagram, Uber, Facebook, Airtable, and Oculus and helped build products used by billions—including Facebook’s News Feed, the standalone Messenger app, Instagram filters, Uber Reserve, ChatGPT, and more. Currently he’s investing in early-stage founders at Felicis. In this episode, Peter dives into his most valuable lessons from building and scaling some of tech’s most iconic products and companies.

What you’ll learn:

Peter’s one‑sentence test for hiring superstars
Why your product (probably) doesn’t matter
Why you don’t need a tech breakthrough to build a huge business
The five PM archetypes, and how to build a team of Avengers
Counterintuitive lessons on growing products from 0 to 1, and 1 to 100
The importance of data flywheels and workflows

Some takeaways:

AGI won’t solve everything: When AGI arrives, it will still require builders to channel that intelligence into products humans want. The hustle and craft will matter more, not less.
Peter’s hiring trick: “In six months, if I’m telling you what to do, I’ve hired the wrong person.” This single principle forces high hiring standards, sets clear expectations, and creates accountability for both manager and employee.
The 5 PM archetypes: Consumer (design-obsessed), Growth (data-driven skeptic), Business/GM (margin-focused), Platform (builds tools for others), or Research/AI (technical depth). Know your type and hire for complementary strengths.
You don’t need a tech breakthrough: Facebook, Instagram, and Uber built billion-dollar businesses on existing technology. The breakthrough was understanding human needs and applying relentless craft.
Managing-up formula: “Say you’re gonna do the thing, say you’re doing the thing, say you did the thing.” This simple repetition ensures alignment, invites course correction, and ensures credit.
Data flywheels beat everything: For AI startups to compete with giants, you need proprietary data that improves through usage. Windsurf succeeded by tracking which code suggestions users accept and reject.
Language shapes reality: Word choice has downstream effects on everything. Peter spent hours on 20-word slide decks because language affects thought, which affects product, which affects outcomes.
The unexpected value of growth teams: At Instagram, Uber, and ChatGPT, Peter’s first move was building a growth team—not for growth hacking but to force measurement rigor and uncover what actually matters.
Create healthy tension: Deliberately hire people with opposing strengths (growth vs. craft, data vs. intuition). The debates between them produce better products than consensus would.
Choose adventure over stability: “If you move a tree, it dies. If you move a person, he thrives.” Optimize for learning and new experiences over safe career paths.
Team composition is more important than individual talent: Think of your team as a product. Design it like a role-playing-game party where everyone has different stats and abilities that complement each other perfectly.
Empathy can’t be summarized: You must feel your users’ pain directly. No ChatGPT summary of user interviews can replace being in the room, hearing the tone, feeling the frustration.
