The web's full of lectures. Lectures are not the bottleneck. The bottleneck is that nobody sequences them for you, brings them back at the right moment, or asks you to use what you just saw. So we built that — and made it the whole product.
For most of history, the best version of education was a tutor: someone who knew what you knew, what you didn't, and what to ask you next. That kind of attention was reserved for the few. We think software can finally give it to everyone — not by replacing teachers, but by handling the parts that don't scale.
Our job is the loop. Diagnose, sequence, reinforce, apply. Do it well, lesson after lesson, for tens of thousands of learners at the same time. The rest — the warmth, the encouragement, the judgment about what's worth teaching — we leave to humans.
We don't measure engagement. We measure mastery. Time-on-app is a vanity metric — we'd rather you finish and leave.
The engine should feel invisible. If you're noticing the personalization, we got the dose wrong.
We don't hire course factories. Every instructor still ships production code. Otherwise the course will read like a textbook.
Every claim about outcomes is backed by a number we publish. If something stops working, we say so first.
We track what you do in the lessons. Nothing else. No data sold, no shadow profiling, ever.
Captions, transcripts, keyboard nav, screen readers. Not a quarter goal — a launch requirement.
Co-founders Maya and Daniel meet in a reading group on retrieval practice. Three months later, the first prototype: a spaced-recall tool stapled onto a single React course. People finished it.
We ship sequencing. The first three courses go live. Cohort completion goes from 28% to 64%. We hire two practitioners — neither of whom calls themselves a “creator”.
Capstones become a thing. Mentor reviews, 48-hour SLA. The catalog hits 30 courses. A small Series A from people we wanted to learn from.
We launch for engineering teams. We publish our first outcomes report — the same dashboard we look at. 41k learners, 87 courses. We're still small. We're still optimizing for mastery, not minutes.
Co-founder, Curriculum
Ex-Stripe staff engineer. Wrote the first React course on a couch in Lagos.
Co-founder, Engine
Ex-Hugging Face ML lead. Reads more about memory than is healthy.
Head of Mentorship
Ex-Datadog principal SRE. Treats code review like a love language.
Eng, Mobile
Built the mobile app on a six-month sabbatical. Now it pays his rent.
Design
Designed every empty state with the same care as the hero.
Research
PhD in cognitive science. Writes the papers we steal from.
Operations
The reason payroll runs and your support ticket got answered.
Working practitioners
Engineers, scientists and designers who still ship — and teach on the side.
Or, you know, work with us. We're hiring across engineering, curriculum and mentorship — fully remote, fully candid.
