How to find hidden growth opportunities in your product

8Frameworks

15Insights

Episode overview

Albert Cheng explains growth as connecting users to a product’s value and presents an explore-and-exploit framework for finding, scaling, and eventually refreshing promising growth insights. Drawing on Duolingo, Grammarly, and Chess.com, he discusses retention, freemium monetization, experimentation systems, brand and community, habit formation, and AI-assisted analytics and prototyping. He also argues that high-agency teams learn faster and recounts how Chariot Direct failed because it began with a solution, neglected operational stakeholders, and attracted publicity before validation.

Key ideas

Growth should connect users to product value across their full journey, rather than optimize isolated metrics through friction or paywalls.
Teams should explore broadly for meaningful insights, exploit validated patterns across adjacent surfaces, and return to exploration as results saturate.
Chess.com increased game reviews and subscriptions by reframing post-loss feedback around brilliant moves, encouragement, and continued learning.
Grammarly nearly doubled upgrades by letting free users sample a limited mix of premium suggestions within their normal writing experience.
Retention is the foundation of consumer subscriptions; mature products should improve existing-user stickiness and design deliberately for resurrected users.
AI can shorten growth cycles through text-to-SQL analysis, experiment summarization, ideation, and rapid prototypes, but tools still need smoother production workflows.
Experiment velocity requires leadership support, trustworthy instrumentation, shared learnings, configurable surfaces, and participation beyond product and engineering.
High agency, clock speed, energy, and a beginner’s mind can matter more than narrowly matched prior experience, especially as AI changes established workflows.

Brand vs Growth Is Wrong. It's Rocket Fuel.

Albert admits he used to see viral brand marketing (Duo the Owl, TikTok, mascots) as opposed to data-driven growth experimentation. Watching Duolingo, he changed his mind: the personality built through product and push notifications feeds the marketing team's memes, and on some days those channels drove 20-30% of new users. Chess.com reinforced it, with pandemic and Queen's Gambit waves quadrupling registrations overnight.

Brand marketing and growth experimentation combine rather than compete
Duo the Owl's personality, built in-product, fueled TikTok/YouTube marketing
Attribution showed those channels driving 20-30% of new users on some days
Steady experimentation plus occasional big cultural waves compound
Chess.com saw registrations quadruple overnight during big waves

“I used to think it was versus, but now I realize that they combine really well. It could be rocket fuel for for your growth.”

Hot Take1:08:00

Hire for Agency, Not Experience (Experience Can Be a Crutch)

The default hiring path fills a JD by poaching from similar companies. But Albert's highest performers were high-agency people with clock speed and energy who didn't necessarily have deep domain experience. In a world shifting fast with AI, learned habits often need to be intentionally discarded, so speed of learning beats experience, and much of that signal shows up outside the formal interview.

Top performers had high agency, clock speed, and energy over deep experience
Experience can be a crutch, especially as AI shifts the ground fast
Learned habits often need to be intentionally discarded; keep a beginner's mind
Bet on the fastest speed of learning
Agency signals appear outside the interview: questions asked, references, energy, whether they went deep on your product

“sometimes that experience could be a crutch in certain ways.”

Why Retention Is Gold (And the D1 Benchmark to Aim For)

For consumer subscription products, retention is what makes the model work; without it, all the pressure falls on getting users to pay on day one, which is brutal. Albert gives a rough benchmark: a D1 retention around 30-40% is solid for a consumer app. Below that, he questions whether you can mathematically acquire enough users to build a large daily active base.

Weak retention forces you into aggressive day-one monetization
D1 retention around 30-40% is a solid mark for a consumer app
Much lower D1 raises doubts about user intent and DAU-base math
Retention is the margin that lets scrappy consumer products survive

“user retention is gold for consumer subscription companies.”
Albert Chen · 28:30

“I think when you have your D1 retention somewhere around like the 30 or 40% mark, like that's quite solid, I think, for for a…”

How Duolingo, Grammarly, and Chess.com Actually Differ

Albert contrasts the three products he grew. Duolingo runs on a rigid, template-driven 'green machine' where the experience changes multiple times a day per user. Grammarly evolved into a product-led-sales/B2B motion where the core product team (not growth) most drives repeat usage. Chess.com is defined by fanatical, chess-obsessed staff who dogfood the product constantly.

Duolingo: highly structured process, product changes multiple times/day per user
Grammarly: product-led sales, core product team drives current-user retention
Chess.com: staff are fanatical chess players who constantly dogfood
There's no single right way; all three succeed very differently
At Grammarly, Albert realized growth was 'getting in the way' of the core product team and handed the metric over

“The product experience of Dualingo actually like changes multiple times per day for each user which is pretty shocking.”

Why Chess Engines Crush LLMs (and Grandmasters)

Albert explains that chess engines like Stockfish are dramatically stronger than any human, calculating tens of millions of positions per second. On the ELO scale, a top grandmaster like Magnus Carlsen is ~2,800 while engines sit around 3,600, so strong an engine could give up a rook and still compete. LLMs, by contrast, are bad at chess because they hallucinate moves and can't go deep on a specific line.

Chess engines are dramatically better than the top grandmasters in the world
Magnus Carlsen ~2,800 ELO vs Stockfish-class engines ~3,600
An engine could play down a rook and still be competitive with the best
LLMs are bad at chess: they hallucinate moves and can't reason deeply on lines
Chess and AI have been intertwined since Deep Blue beat Kasparov in 1997

“A top grandmaster like Magnus Carlson is like a 2,800 and then Stockfish and similar engines are like 3600.”

Why New Chess Players Are So Hard to Retain

Over 75% of chess.com's new users self-identify as complete beginners, and beginners have a rough first experience: fewer than a third win their first live game. Since losing a game retains 10% worse than winning, and you can't simplify chess's rules, the team crafts gentler onboarding, like a delightful learn-to-play flow and hiding your rating for the first five games.

Over 75% of new users classify themselves as new or beginner

The Chess.com Positivity Flip That Grew Reviews 25%

Chess.com found that 80% of players review a game after a win, not a loss, which contradicted the feature's original design assumption. So they flipped the post-loss experience to surface brilliant moves and encouraging coach messages instead of blunders. That single change grew game reviews 25%, subscriptions 20%, and lifted retention significantly.

80% of people who review their games do so after a win, not a loss
The team originally assumed players wanted to study their mistakes
After a loss, they now show best moves and encouraging coach copy
Result: +25% game reviews, +20% subscriptions, large retention lift
The insight was then spread to adjacent teams (puzzles, etc.) to compound

“what he observes is that 80% of people that review their games actually do so after a win”
Albert Chen · 11:30

“That change alone was pretty dramatic for us. It grew game reviews by 25%, subscriptions by 20%, user retention by a lot as well.”

The Grammarly Move That Nearly Doubled Upgrades

Most free Grammarly users experienced it as a spelling-and-grammar fixer because those were the only free suggestions shown. The team interspersed a limited taste of paid suggestions (tone, clarity, rewrites) directly into free users' writing. Despite fears of giving too much away, upgrade rates nearly doubled because users suddenly saw Grammarly as far more powerful.

Free users only saw correctness suggestions, so they undervalued the product
They sampled paid suggestions intermingled into free users' writing in real time
Concern that giving features away would kill conversion proved false
Upgrade rates nearly doubled from the change
Lesson: make your free product a reflection of everything the product can do

“all of a sudden people were seeing Gramly as a much more powerful tool than they were before and our upgrade rates like nearly doubled…”

The 1,000-Experiments Goal He Openly Made Up

Chess.com went from practically zero experiments before 2023 to ~50, then ~250, with a target of 1,000 next year. Albert cheerfully admits he invented the number. The point isn't hitting it; a stretch goal forces the conversation about what would have to be true to get there, which surfaces the need to enable experimentation across lifecycle marketing, app store assets, and no-code screens.

Chess.com barely experimented before 2023; ~50 last year, ~250 this year, 1,000 target
Albert openly admits he made the 1,000 number up
A goal's value is forcing the 'what would need to be true' conversation
Hitting the number matters less than the capabilities it unlocks
Enables experiments in lifecycle marketing, app store assets, and no-code screens

“Did I make it up? Yes, absolutely. I made it up.”

Story1:01:30

The Experiment Tool That Had Retention Backwards

Albert warns that the experimentation system matters as much as any single experiment, and instrumentation is where it breaks. At one company, an in-house tool had user retention configured backwards for three months, so every positive result was actually negative. It's a cautionary tale for why you must instrument your product thoroughly before trusting results.

The system and instrumentation matter as much as any single experiment
One in-house tool had retention configured backwards for ~3 months
All 'positive' results were actually negative during that window
Bad instrumentation produces wonky, misleading experiment results

“we realized that user retention was actually configured backwards. So all positive results were negative results.”

How Duolingo Found Its Viral Moments With Screenshot Tracking

Rather than forcing virality, Duolingo added temporary screenshot tracking to discover where users were already organically sharing. Hotspots included streak milestones and funny challenges (not, say, advancing in the leaderboard top three). They then staffed those exact moments with illustrators and animators to make them far more delightful, driving 5-10x more sharing.

Virality is hard to manufacture; find where users already share
Temporary screenshot tracking revealed organic sharing hotspots
Streak milestones and funny challenges were highly shared; leaderboard climbs were not
They staffed those moments with illustrators/animators to amplify them
Leaning into existing behavior drove roughly 5-10x more sharing

“we invested actually in some time to um essentially add screenshot tracking for like a brief period of time in the app”

The Chariot Failure: A Solution Searching for a Problem

At the commuter-shuttle startup Chariot, Albert's team built 'Chariot Direct' to add Uber/Lyft-style dynamic routes onto fixed shuttle lines. It failed, teaching three lessons: it was a solution searching for a problem rather than a real user need; in a marketplace they over-focused on the rider app and neglected drivers and operations; and they ran PR before validating demand, which created sunk-cost pressure to see a doomed idea through.

'Chariot Direct' added dynamic Uber/Lyft-style routing to fixed shuttle lines and failed
Lesson 1: don't chase 'wouldn't it be nice' ideas; start from a real user and problem
Lesson 2: in marketplaces, there's more than one end user; they neglected drivers and ops
Lesson 3: heavy PR before validation created costly sunk-cost momentum
The opposite failure mode of validating everything before telling anyone

The Text-to-SQL Slack Bot That Answers Data Questions

Chess.com is building a Slack bot that takes ad-hoc data questions (e.g. subscribers in South Africa) and actually runs the analysis, not just generating a query. It replaces the slow loop of a data analyst prioritizing and running one-off requests. A side effect: because people are less embarrassed asking a bot, question volume explodes and the company becomes more data-informed.

A Slack bot performs the actual analysis via text-to-SQL, not just query generation
Removes the bottleneck of analysts triaging one-off ad-hoc questions
Lowers social friction so people ask questions they'd otherwise avoid
Result is a large increase in questions asked and a more data-informed company

Mature Companies Grow by Resurrecting Dormant Users

As a company matures, the biggest retention lever shifts from new users to existing habitual users, whose retention compounds into a daily habit. Mature products also stack up hundreds of millions of dormant and sporadic users, so reactivated and resurrected users become as large a component as brand-new ones. It's worth designing a deliberate experience for resurrected users, as Duolingo does with social notifications and placement re-tests.

Existing-user retention compounds and builds the daily habit that matters most
For mature products, reactivated/resurrected users rival new users in volume
Dormant and sporadic users accumulate into hundreds of millions
Design a deliberate 'resurrected user' experience for strong ROI
Duolingo uses social push notifications and placement re-tests to bring users back

“it's that retention rate that really compounds and build that builds that daily habit.”
Albert Chen · 31:00

“it's actually like pretty interesting that the components of your active user base are actually not heavily weighed in the new user set after you…”

Takeaway1:10:30

Everyone Has a Company Stage Where They Shine

Albert believes everyone has a company stage that fits them best. Having done big tech, tiny startups, and the middle, he landed in a medium-sized 'goldilocks zone': companies of ~500-1,000 people, typically 10-20 years old, durable and ideally profitable but still at key inflection points. It gives him both scale and the ability to execute on a daily/weekly rather than monthly/quarterly cadence.

Everyone has a company stage where they perform best
Big tech offers scale but moves slowly; tiny startups move fast but are grueling and unknown
His goldilocks zone: ~500-1,000 people, 10-20 years old, durable, ideally profitable
These companies are at inflection points, not stagnant
The sweet spot balances scale with a daily/weekly execution pace

“I I definitely believe that everyone has a company stage that they shine best at.”
Albert Chen · 1:11:00

“these companies that we've talked about in the podcast are about 500 to a,000 people.”
