Stop collecting course certificates as trophies.My folder had 14 of them. "Intro to LLMs." "Prompt Engineering Specialization." Little PDF badges of weekends I'll never get back — and not one helped when my CTO asked why our retrieval was returning garbage.Every time the AI anxiety spiked, I'd buy another course. Enroll. Watch two modules at 1.5x. Screenshot the certificate. Feel productive for 48 hours. Back to nodding in meetings. Zero shipped AI features.Nobody at work cares about your certificates. They care whether you can debug the eval, scope the project, ship the thing on Monday.Sounds like you?Then check out Dexity.We built Dexity because we kept watching smart professionals drown in 60-hour curriculums they'd never finish. So we cut the theater. One in-demand AI skill. A handful of focused sessions. Taught by someone who builds it at a FAANG+ company on weekdays — not a course creator who recorded a module in 2023 and moved on.Take AI Evals for PMs, for example. Session one, the instructor pulls up an eval harness he's running at his company that week — the actual rubric, the actual failure modes, the messy judgment calls. Not a toy example. By week 3 you're designing evals for your own product. By the end you've shipped a measurement framework your team actually uses, and you stop being the PM who hand-waves "the model seems better."No certificate. Just a thing that works, and a teammate going "wait, you did that?"That's the trade we're offering: trophies for skills. Theater for proof.Dexity is live on Open Hunts today. If your trophy folder is feeling heavy — come learn one thing properly. 👇
