Cold open: Why algorithms still need product intent and human judgment
Adriel sets the tone with a critique of “techno-utopian” thinking that algorithms will automatically do the right thing if you just feed them data. He frames a core PM responsibility: defining what machines optimize and where humans must make the calls.
- •Algorithms often miss long-term effects and second-order behavior changes
- •Models don’t understand product intent unless you encode it explicitly
- •PMs must define decision frameworks: human vs machine responsibilities
- •Designing algorithmic products is also designing human-computer interfaces
- 0:39 – 5:01
Show setup: Adriel’s roles across Reddit, Lyft, and early Facebook growth
Lenny introduces the podcast’s goal and Adriel’s background as a product leader across several iconic consumer companies. He previews the major themes: growth, diversity, operating amid controversy, and the future of AI.
- •Adriel’s current role: VP Product at Reddit (incubation/new bets)
- •Past leadership: Lyft marketplace/pricing; early Facebook user acquisition
- •Episode topics: growth hacking, product leadership, diversity, AI
- •Positioning: spotlighting “under the radar” high-impact product leaders
- 5:01 – 6:06
From Trinidad to tech: consulting, Intuit, and the path into product
Adriel gives a rapid career overview, starting with growing up in Trinidad and moving to the US for engineering school. He traces pivots through consulting, early mobile work at Intuit, and eventually into high-scale consumer tech.
- •Origins in Trinidad & Tobago; US college in electrical engineering
- •Early career in consulting across heavy industry and energy
- •Shift into tech: Intuit’s early iPhone app era
- •Formative experience: Facebook growth/user acquisition; later biotech and Lyft
- 6:06 – 7:34
What Reddit X does: evolving how people interact on Reddit
Adriel explains Reddit X as an incubation team focused on new modes of interaction, not “moonshots” for their own sake. The emphasis is on changing how conversations happen—speed, audience, media types, and permanence.
- •Reddit today: asynchronous conversations among (often) anonymous strangers
- •Reddit X focus: new interaction modes—tempo, audience, and context
- •Exploring richer media: video/audio and different “permanence” models
- •Pragmatic orientation: focus on scalable, current platforms vs pure metaverse bets
- 7:34 – 8:32
Avatar marketplace + NFTs: practical ownership, messy tech, real value
They discuss Reddit’s avatar marketplace and why NFTs were used under the hood. Adriel separates the underlying idea (creator rights/acknowledgment) from the speculative and sometimes harmful uses of NFT ecosystems.
- •Creators sell digital avatar art directly within Reddit
- •NFTs as enabling tech: public proof/acknowledgment of creator rights
- •Digital goods marketplaces need better IP/ownership primitives
- •Acknowledges “nefarious” and wasteful NFT usage while seeking legitimate applications
- 8:32 – 11:10
How R&D/incubation teams avoid “organ rejection” inside big companies
Adriel shares what makes innovation teams succeed culturally inside mature orgs. The core is alignment: the work must feel mission-critical, shared across the org, and not framed as the only place where innovation happens.
- •Common failure mode: the org rejects incubators as “not part of the body”
- •Make the work clearly core to the company mission
- •Ensure wins feel shared—avoid resentment over resources and “fun projects”
- •Signal that innovation can happen everywhere; incubators handle capacity gaps + longer bets
- 11:10 – 14:58
Being the first Black PM at Facebook: Trinidad’s influence on product thinking
Adriel reflects on how his upbringing shaped his product instincts and why representation changes what gets built. He shares a concrete example: assumptions about phones, SIMs, and identity that matter deeply in global growth.
- •Adriel was the first Black PM at Facebook (about ~30 PMs then)
- •Trinidad as a lived “melting pot” (ethnicity, religion, class) informs perspective
- •Challenges common tech assumptions: 1 person ≠ 1 device ≠ 1 phone number
- •Global product design benefits when teams include people with non-US lived experience
- 14:58 – 19:42
Diversity as a speed and quality advantage—and the retention prerequisite
He argues diversity isn’t just moral; it creates direct business value by improving product decisions faster. The key unlock is treating diversity as core to performance so that diverse talent is supported and retained, which then improves recruiting.
- •Diverse teams can “simulate” global user perspectives internally via debate
- •Avoid “colonial” product design from a monoculture tower
- •Real progress starts when leaders see concrete business value (not just PR pressure)
- •Retention is the crux: cultures must reward, use, and protect diverse perspectives
- 19:42 – 28:15
Working at controversial companies: buffering teams and separating noise from truth
Lenny asks about operating in high-PR, high-controversy environments (Facebook, Lyft, Reddit). Adriel emphasizes the PM’s role as a stabilizer and the discipline of finding which criticism is valid by staying close to users.
- •PM as a “damping” force: steady teams in both praise and backlash
- •Some controversy is inevitable when you change entrenched power structures
- •Critical skill: distinguish valid criticism from threatened incumbents’ narratives
- •Staying close to users is the best compass amid media cycles
- 28:15 – 31:08
Lyft story: driving as research—and what it taught about fair pay and incentives
Adriel explains how he personally drove for Lyft to understand driver complaints during major public debates. A single ride highlights the mismatch between customer value and driver compensation, and the complexity of balancing rider prices, driver pay, and service reliability.
- •Firsthand research: Adriel drove to experience driver economics directly
- •Example ride: long pickup for a very short trip reveals compensation gaps
- •Customers may value pickup time, but pricing/pay systems may not reflect it
- •Balancing: driver fairness, rider affordability, and avoiding perverse incentives
- 31:08 – 35:15
Operational control: why marketplaces can’t be “set-and-forget” algorithms
He shares his most stressful Lyft moment: unwinding a complex pricing algorithm that worked in limited contexts but became operationally inflexible at scale. The lesson is that ops requirements and human-in-the-loop controls must be first-order in product design.
- •Stressful lesson: a complex pricing model was hard to operate and change across cities
- •Scaling exposed hidden requirements: frequent, local price changes are unavoidable
- •Operational control means humans can intervene for taxes, seasons, competitors, emergencies
- •Designing ops tools + guardrails is a core product responsibility, not an afterthought
- 35:15 – 42:40
Designing human + machine decision systems (and a quick Neuralink detour)
Adriel expands the principle: algorithms optimize well but can’t make strategic trade-offs or understand intent unless humans encode it. They discuss how product leaders should design interfaces that let people steer outcomes—then use machines to amplify that intent.
- •Techno-utopian fallacy: “feed data + objective” ignores intent and downstream effects
- •Strategic constraints/trade-offs must be set by humans
- •PMs are “tool designers”: machines should amplify intent, not replace judgment
- •Neuralink tangent: better interfaces raise the question of who is truly in control
- 42:40 – 51:30
Thoughts on AI risk: exponential progress, high-cost low-probability outcomes
They explore AI fears and whether systems could quickly surpass human capabilities. Adriel’s stance: today’s systems still look like tools lacking judgment, but the tail-risk is worth serious attention because the downside is so large.
- •Current AI impresses (images/text) but still lacks robust judgment/decision-making
- •Humans struggle to reason about exponential curves—risk can be underestimated
- •Even remote catastrophic scenarios warrant attention due to extreme downside
- •Focus remains on human-guided tools rather than autonomous replacements
- 51:30 – 56:06
Facebook growth: beyond hacks—core actions, “cannonballs,” and a rallying metric
Adriel demystifies growth hacking: the durable wins came from grinding on fundamental actions (discoverability, signup, finding friends) and occasionally making big “cannonball” investments. He also explains why “X friends in Y days” mattered most as an organizational rallying cry, not a magical threshold.
- •Growth hacks help, but you can’t “hack” your way around missing user value
- •Core growth loop: make it easy to find the product, join, and find friends
- •Cannonballs = big fundamental investments (e.g., phone-number signup, global SMS delivery)
- •“7/10 friends” metric: memorable goal that galvanized execution more than precise correlation
- 56:06 – 59:10
Marginal users + experimentation portfolio: when data helps and when it misleads
Adriel defines the “marginal user” as someone on the cusp of converting and shows why observing real users is essential to uncover root causes. He then outlines an experimentation philosophy: avoid getting trapped in endless micro-tests and manage a portfolio of big bets and smaller iterations depending on product maturity.
- •Marginal user method: find places with high intent (traffic) but low conversion
- •Study worst-case experiences to reveal everything that’s broken, then prioritize what’s fixable
- •Data shows where it hurts; user observation reveals why it hurts (orthogonal issues)
- •Experimentation: success rates aren’t the point—avoid “incremental laziness” with a balanced bet portfolio
- 59:10 – 1:02:57
Senior PM growth: organization, empathy, and leading through others
Adriel explains the biggest skill shifts as he became more senior: designing effective organizations and practicing deeper empathy with peers and teams. He frames leadership as creating clarity, safety, and smooth execution environments so others can do great work.
- •Senior impact comes from teams and systems—not individual brilliance
- •Organization design: clear goals, incentives, processes, and unblocking execution
- •Empathy expands beyond users to cross-functional partners and teammates
- •Key move: “take your own shoes off” to understand motivations and find shared objectives
- 1:02:57 – 1:07:25
Lightning round + closing: books, podcasts, shows, interview question, and a simple ask
In the lightning round Adriel shares eclectic recommendations spanning geopolitics, cars, and TV, plus a favorite interview prompt to test communication and empathy. He closes with where to find him and a small action for listeners: talk to someone different for five minutes.
- •Book picks on energy/geopolitics: Daniel Yergin’s work
- •Podcast favorites: Revisionist History; plus a niche car-tuning pod
- •Favorite interview question: “Teach me something you don’t think I know”
- •Closing request: seek out a brief conversation with someone different from you
