The Computomatix Times

My biggest takeaways from @petersellis:

1. There is always money in the banana stand. The highest-ROI growth move is usually investing in the core product, vs. chasing side quests. At @Snap, after the disastrous 2018 redesign caused DAU to flatten, the team laser-focused on performance for existing users—particularly on Android—and sparked a multi-year growth renaissance. At @Discord, rather than chasing @Midjourney’s moment, the team focused on making Discord the best place to play intentional multiplayer games with friends. The result was some of the fastest growth in history.

2. Great taste is knowing when to stop. Peter spent seven years watching @evanspiegel personally say no to better ideas than most consumer startups ever launch. His take on taste is that the difference between people with it and people without it is that the ones with taste stop one step before everyone else does. They know when a good idea’s time has come, or when it has to sit on the shelf a bit longer.

3. Spend your time on your best people, not the ones struggling. Against human instinct, which is to help whoever looks like they’re drowning, Peter consistently loads up his strongest performers with more responsibility and decisions until he finds the limit of what they can handle.

4. The median PM is bad, and even net negative, because the skills of a great product leader are the skills of a founder or an executive, so top-percentile PMs leave for founder and exec seats. On the other hand, mediocre PMs fight to stay in the job because the job pays well and has status. ZIRP made it worse because it was the most lucrative role in tech for non-technical people, with the most subjective sense of what great looks like. A lot of engineers and designers conclude “PMs suck” because they have mostly met the bottom of that distribution.

5. Great PMs hold three contradictory traits. First: deep confidence bordering on arrogance, paired with genuine humility. Second: extreme organizational discipline, paired with near-pathological comfort with ambiguity. Third: a long-term vision that’s always holding in the background, paired with a day-to-day bias for action.

6. Peter designs product teams like terrorist organizations: a shared ideology and an explicit map of who is trusted with which decision. You will almost never hear a leader tell their team to collaborate less, but coordination makes you as slow as the slowest node, which compounds and slows organizations down. The antidote is a strong shared ideology and clear DRIs who can make confident, founder-quality decisions quickly.

7. Optimize consumer products for daily active use. Days map to real human cycles; weeks and months are weaker. One daily user equals roughly 30 monthly users in simple math, which is why elite consumer products run extremely high DAU/MAU. Moving that ratio a few basis points often beats acquiring a pile of soft monthly actives and hoping they retain. DAU/MAU is next-day retention under another name.

8. Define a “Core Product Value” that's both a memorable phrase and a set of metrics that measure it. Peter built this framework at both Snap and Discord. At Snap, it was “the fastest way to share a moment with the people you care about,” which you could actually decompose into metrics: time to load (fast), camera-open-to-share rate (share a moment), best friends engagement (people you care about). At Discord, it was “the best way to talk and hang out with your friends before, during, and after playing games,” with a corresponding L7 and Lness definition that made its way into the growth playbooks. The phrase without the metrics is a slogan; the metrics without the phrase are a dashboard. You need both.

9. The most important career decision you make as a PM is who you choose to marry. This has compounding effects on your career that no podcast, course, or mentor can replicate. The intellectual sounding board, the support system, the person who challenges you to grow—that relationship shapes your capacity to operate at the highest level in ways that are genuinely hard to quantify but nearly impossible to overstate.
