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

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 *Brought to you by:* WorkOS—Make your app enterprise-ready, with SSO, SCIM, RBAC, and more: https://workos.com/lenny Mercury—Radically different banking, now with Command: https://mercury.com/ *Episode transcript:* https://www.lennysnewsletter.com/p/90-minutes-of-unfiltered-product *Archive of all Lenny's Podcast transcripts:* https://www.dropbox.com/scl/fo/yxi4s2w998p1gvtpu4193/AMdNPR8AOw0lMklwtnC0TrQ?rlkey=j06x0nipoti519e0xgm23zsn9&st=ahz0fj11&dl=0 *Where to find Peter Sellis:* • X: https://x.com/petersellis • LinkedIn: https://www.linkedin.com/in/disgruntled • Website: https://pjs.lol *Where to find Lenny:* • Newsletter: https://www.lennysnewsletter.com • X: https://twitter.com/lennysan • LinkedIn: https://www.linkedin.com/in/lennyrachitsky/ *In this episode, we cover:* (00:00) Introduction (02:48) Why Peter avoided podcasts until now (05:44) Designing teams like terrorist organizations (10:35) Cult versus terrorist org: the key distinction (11:19) Managing Nikita Bier (12:56) Building orgs that handle spiky talent (15:16) Why the median PM is probably bad (18:28) Is the PM profession getting better?

WHAT IT’S REALLY ABOUT

Peter Sellis on product teams, moats, growth, and ads reality

  1. Peter Sellis explains his approach to building high-performance product orgs by minimizing collaboration overhead and clarifying ideology and decision ownership.
  2. He argues the product management talent distribution and incentives produce a weak median PM, and describes Snap’s historical “PM must add value over nobody” standard as a useful bar.
  3. Sellis diagnoses Snap’s ad-monetization challenges as structural—young audience constraints, camera-first creation flow, and messaging’s weak ad fit—despite Snap’s strong consumer product track record.
  4. He reframes “systems thinking” as mathematically modeling inputs, outputs, and distributions to find real levers, rather than relying on vague frameworks.
  5. Across Snap and Discord, he claims durable growth typically comes from improving the core product’s retention/frequency, while discussing when to make non-core bets and how SpaceX avoids the innovator’s dilemma by sunsetting even its best products.

IDEAS WORTH REMEMBERING

5 ideas

Design teams for high autonomy + clear decision trust, not constant collaboration.

Sellis argues collaboration’s coordination overhead makes teams move at the speed of the slowest node. He prefers high autonomy with crisp decision rights, relying on shared ideology/strategy shorthand so teams can act without constant alignment meetings.

The median PM can be net-negative unless the org enforces a “value over nobody” bar.

He believes PM skill is effectively power-law distributed: top PMs often “exit” into founding/executive roles, while incentives keep weaker PMs in-seat. Snap’s “value over nobody” bar (operate without PMs; PM must add incremental value) is offered as a corrective standard.

Snap’s monetization constraints are rooted in audience + format + product nature.

Snap’s ads ceiling wasn’t just execution—it was structural: (1) very young users are harder to target/measure (regulatory + attribution constraints), (2) the product opens to the camera (creation flow) rather than an ad-friendly feed, and (3) messaging utilities are historically hard to monetize with ads.

Real systems thinking is model-building and causal leverage identification, not buzzwords.

His practical definition of systems thinking is the ability to model a system with inputs/outputs/levers (often in a spreadsheet) and understand distributions, not just repeat “five whys.” The goal is to identify causal levers and where constraints/feedback loops actually live.

Big growth often comes from improving the core experience for existing users.

He claims much growth comes from increasing “frequency/retention” in the core cohort (e.g., improving DAU/MAU) rather than chasing shiny adjacent bets. At Snap, Android performance post-redesign drove a growth renaissance; at Discord, doubling down on gamers (despite claims of “100% penetration”) unlocked fastest growth since the pandemic.

WORDS WORTH SAVING

5 quotes

A good terrorist organization essentially has two things. One is it has this ideological culture that everyone understands why they are doing what they're doing, and then it has a very, very clear organizational structure of who can be trusted with which decision.

— Peter Sellis

If somebody is strong and crushing it, I'm just handing them more and more rope to hang themselves with.

— Peter Sellis

The great product managers are exiting the system. They're becoming founders, they're becoming executives. It's kind of set up to be this profession where the median product manager is actually probably pretty bad.

— Peter Sellis

Exercising that kind of muscle of saying no, of restraint, is probably one of the few muscles of taste you can exercise. If a museum has all of their collection on the walls, then the curator hasn't done anything.

— Peter Sellis

Time has no signposts upon which to drape duration. Um, from nothing to nothing is no time at all.
