Every masterclass is moderated, interactive, and built around what you can actually use.
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.
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.
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.
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.
Each month opens 10 live masterclass slots. 21 are already confirmed across the first three months — recognizable names, real ship-it topics — with the rest filling in week by week, shaped by what the cohort asks for. As a founding member you're here at the start.
Most masterclasses are locked months ahead; the remaining slots each month are shaped by what the cohort asks for. Multi-session workshops run alongside — members get 20% off.
