Practical primers on what school skipped — money, contracts, your own habits, and more. Every topic is $1, part 1 always free.

Lacuna is a $1-a-topic learning platform for the stuff school never got around to — negotiating a salary, reading your own blood test, the practical things everyone's expected to just know. Every topic is a handful of short parts you can get through in about 20 minutes, and the first part of anything is always free, so you know what you're paying for before you pay for it. No subscription required — pay $1 once and it's yours forever, or get All-Access for $20/year if you're reading a lot. Finish a topic and you get a real certificate, shareable with one link. We built it because most online learning asks for a big time or money commitment before you know if it's any good — Lacuna asks for neither.

Finally something that doesn't assume I learned this stuff somewhere. The $1-per-topic model is genius for someone like me who only needs one primer on negotiating rent.
