Duolingo
Each of these is a real decision Duolingo is working through, written so you can make the call yourself — incomplete information, someone who pushes back, no answer key.
Duolingo is a consumer digital education company that provides a freemium mobile and web learning app with short, game-like lessons in languages, math, music, and chess, along with the Duolingo English Test, a remote, on-demand English-proficiency assessment used for purposes such as university admissions. Its learning formats include Stories, DuoRadio, Adventures, and Video Call. Its key business drivers are subscriptions, ads, and in-app purchases. Duolingo runs 300+ experiments at a time with its user base to make data-driven decisions. Production workloads run on core compute primitives based on Kubernetes, across different regions and cloud providers.

The rest
Trace lesson loops while weekly releases keep moving
iOS learners are being returned to a completed exercise while their streak still advances. You must weigh a faster diagnosis against evidence engineers can trust before changing production code.
Turn real conversations into practice without derailing daily lessons
Learners preparing for specific conversations are seeking practice outside their usual short lesson routine. You must weigh personal relevance against a flow that remains simple enough to become a repeat habit.
Settle how Energy limits are explained before today's cutover locks
Support contacts rose 34% in the limited rollout, and affected learners may lose their daily practice window. You must weigh a fixed access boundary against an explanation and recovery path people can trust.
Smooth the ad exit while the next lesson still feels immediate
Next-lesson starts fall from 68% to 57% after free learners close an ad. You must weigh ad delivery against a transition that keeps a short practice session moving.
Secure curated buyers without crowding daily lesson sessions
Agency groups will not commit premium spend until they can buy clearer learner contexts. You have to weigh durable programmatic revenue against a daily practice flow that frequent learners will keep returning to.
Hold an annual buy while outcome terms reshape delivery
A major buyer may pull a $2.4 million annual commitment after brand lift missed its threshold. You must weigh accountable commercial terms against delivery certainty and uninterrupted learner sessions.
Rework a stalled PMP before the buyer shifts budget
The live deal is spending below plan because its floor limits eligible impressions. You must weigh faster pacing against the premium ad experience learners expect.
Show progress in week one without crowding the lesson flow
New learners finish early lessons but leave before a daily routine takes hold. You must weigh a clear progress cue against keeping the post-lesson flow focused.
Protect Super access before the next iOS rollout
1.8% of active Super learners see a paywall after updating, despite valid subscriptions. You have to weigh uninterrupted practice against the risk of granting premium access without verified entitlement.
Unstick the next lesson when an ad request lags
Affected free iOS learners continue to another lesson only 71% of the time after completion. You must weigh a faster learning handoff against preserving eligible ad delivery.
Show learners why paid practice is worth keeping without a hard sell
Regular trial learners are leaving paid access even after a month of frequent practice. You have to weigh a clearer paid story against preserving the habit that made the trial valuable.
Decide whether Super or Lite leads renewal without hurting daily habits
Trial-to-paid conversion has fallen to 14% as regular learners encounter conflicting plan choices. You must weigh a faster revenue recovery against the risk of weakening post-renewal daily practice.
Reorder annual plans so solo learners stop abandoning the paywall
Solo learners are leaving the annual paywall after Family appears first, and Individual completion is 6.4%. You have to weigh a clearer solo path against keeping Family visible for learners who need it.
Choose which past concepts to revisit so learners return tomorrow
Learners can revisit completed lessons, yet many leave without choosing what to practice next. You must weigh a more guided review habit against keeping daily practice simple and optional.
Settle access to Video Call before renewal messaging starts
Video Call use is climbing among Super learners, but the renewal signal and Max upgrade signal point in different directions. You have to weigh a clearer Super benefit against the value Max subscribers expect to keep.
Fix the purchase screen so short-streak learners return the next day
Next-day lesson completion fell among free learners who opened the new purchase screen. You have to weigh stronger plan discovery against the daily habit that makes learners return.
Settle which plan fits a learner when the trial ends
Trial-ending learners are reaching checkout after a month of premium practice and hesitating between plans. You must weigh useful plan guidance against a purchase flow that stays simple enough to finish.
Migrate Max access before renewals split across devices
Active Max subscribers are receiving conflicting premium access across devices as renewal approaches. You must weigh uninterrupted practice against irreversible entitlement and billing mistakes.
Restore checkout retries for Super learners within 48 hours
Android learners who leave checkout are cycling back to the paywall instead of retrying their purchase. You need to protect experiment assignment while restoring a clean path to checkout.
