## Why this can grow

A mixed business gets confusing when every dollar is treated as the same kind of demand. Duolingo says it earns revenue from subscriptions, in-app advertising, the Duolingo English Test, and in-app purchases. Those streams behave differently. A subscription needs habit and upgrade intent. Ads need reach and session volume. A test product needs trust and a high-stakes use case. In-app purchases need moment timing. A founder should keep those streams separate long enough to see which loop is actually growing, which one is subsidizing the others, and which one is hurting the user's reason to return.

## Ian's take

From scaling consumer platforms across MENA and Southeast Asia, my default is to distrust growth work that only looks good in a slide. My bias is to treat this as a small market test first. Make the audience narrow, make the promise concrete, and let the first real response decide whether it deserves more work. For conversion, I would strip the test down to one promise, one proof point, and one next step. Confusion kills good demand. For this tactic, I would watch one clear growth signal before putting more time or budget behind it.

## Action plan

1. Define one narrow startup segment where duolingo revenue stream split before one growth story can create a measurable lift.
2. Turn the tactic into one offer, page, campaign, or workflow for the Analytics and Monetization channel.
3. Use the evidence from sec.gov to set the first version of the message, format, and audience.
4. Launch a small test for 7 to 14 days with one success metric: one measurable growth signal.
5. Review the result, keep the winning message, remove weak variants, and turn the learning into a repeatable growth playbook.
