The number that matters isn't enrolment

We enrolled 28,000+ learners across our online courses. The number I actually watched was how many came back on day two.

Enrolment is a vanity metric. It measures your marketing, not your course.

Online learning leaks badly — most programs lose the overwhelming majority of starters. For years the industry blamed learners: too busy, not motivated enough. After building 5 MOOCs and 11 modules on Coursera and edX, I think that’s mostly wrong.

Retention is an engineering outcome, not a willpower problem. Three levers moved it most for us:

1. Time-to-first-win. If a learner finishes something useful in the first session, they come back. We front-loaded value instead of front-loading syllabus.

2. Cadence beats self-paced. Cohorts with a deadline and peers held learners that pure self-paced never did.

3. Visible relevance. Adults stay when the next lesson obviously maps to a real task they have this week.

None of this is about better content. It’s about better design around the content.
