Learn live from 18 practitioners who build the tools you use and ship this work for a living.
PyMC Labs · Apache Arrow · Columbia · Wharton · Loyola · Princeton ORFE · the Phillies · SportsDataverse · and more — with more joining through 2026.
18 instructors. 7 countries. More joining through 2026.
You're in the room, not the audience.
Every masterclass is moderated, interactive, and built around what you can actually use.
Built alongside, not behind glass.
Open your editor next to ours. The instructor writes the code; you write yours. Stuck? Drop a question in the moderated chat — they answer it live.
Q&A with people who built it.
Every session ends with moderated Q&A. Ask Nic Crane about Arrow internals. Ask Chris Fonnesbeck about PyMC. Direct, in the room, while the work is fresh.
Production, not theory.
Real datasets, production patterns, code built to ship and survive contact with a real repo. You leave each session with something you can actually use.
The calendar isn't fixed — it's yours to shape.
Every month we survey the cohort on what to cover next and build sessions around what members actually need. You're not buying a frozen curriculum; you're joining a room that adapts to the work you're doing right now.
10 live sessions a month. Here's what's locked in.
Each month opens up 10 live masterclass slots. Ten are already confirmed across the first three months — alongside another 20 slots filling in week by week. As a founding member you're here at the start: you'll watch the calendar fill in, and you get a say in what gets added.
10 live slots per month. Instructors and topics are confirmed two weeks before each session, shaped by what the cohort asks for.
