Learning should be fast and focused.
A Co builds 15-minute micro-courses for professionals who need to close a specific skill gap — right now, not next semester.
The Problem
You need to learn one specific thing — say, SQL window functions, or how to use Git interactive rebase. But every course out there is 4 hours long, covers 50 topics you already know, and buries the one thing you need under hours of padding.
That's not a learning problem. That's a search problem. And we built A Co to solve it.
Our Approach
Every A Co course targets exactly one hyper-specific skill. We strip away introductions, prerequisites, and filler. You get 15 minutes of dense, practical instruction — and then you're done.
Each course costs $9 because great teaching doesn't need to be expensive. We'd rather you buy the three courses you actually need than subscribe to a library of thousands you'll never watch.
What We Believe
Specificity wins
A course called "Figma Auto Layout Mastery" is more useful than a course called "Complete Figma Guide".
Respect people's time
If it can be taught in 15 minutes, it should be taught in 15 minutes. Not stretched to fill a runtime.
Pay per skill, not per month
Subscriptions incentivize volume. Per-course pricing incentivizes quality and focus.
