Our own project: software we built and operate ourselves.

Tenzan Academy

Training that stays in your head. 21 courses for companies: 13 technical, from Python, SQL and Rust to LLMs and application security, and 8 business, from GDPR to finance and team management. You learn through quizzes, flashcards and real code: you answer instead of reading slides. The method is grounded in memory research.

Corporate training that actually sticks

Slide decks and webinars are easy to organize but hard to remember: a week after training, a team remembers a fraction of the material, and slides rarely show real code. Tenzan Academy teaches actively: short, color-coded chunks of knowledge with working code, flashcards for self-testing, and a quiz that forces you to recall the answer, not just recognize it.

03How it works

Four learning mechanics, one platform

Color-coded knowledge

Every block of material carries a color: yellow = fact, red = term, green = mnemonic, orange = pitfall (the mistake people actually make in practice). The brain links color to knowledge type faster than reading a label.

Real code, not just theory

Every section has a working code example in a readable, highlighted block: not a syntax description, an actual snippet that illustrates the pitfall or pattern.

Active recall

Flashcards with the answer hidden, not passive re-reading of notes. Retrieval practice strengthens the memory trace far more than reading alone.

Quiz as learning, not a test

24 questions per course, order and answer choices shuffled on every attempt, an explanation right after each answer.

04Numbers

Twenty-one courses, zero backend

21

courses ready to use out of the box: 13 technical (Python, Rust, Go, SQL, Cloud/DevOps, AI, AppSec) and 8 business (GDPR, finance, negotiation, workplace safety, team management).

504

quiz questions and 448 flashcards: the team practices recalling knowledge instead of clicking through slides, 24 questions and 20+ flashcards per course.

222

working code examples: the team learns from snippets that actually run, not pseudocode on slides.
