Software for the trades, built so people pass.
Deeun builds VoltExam — the first mobile exam prep tagged to the exact code section, with explanations grounded in the actual jurisdictional code book. 42 licensed trades and certifications, in your pocket.
So the people who keep the lights on, the water flowing, and the buildings standing earn faster.
For 50 years, tradespeople studied from photocopied PDFs.
Heavy code books. Outdated study guides. Static practice tests with no feedback. The same materials, semester after semester.
First-time test takers fail. That's another exam fee. Another wait period. Another month before they can earn a journeyperson wage.
A precision instrument, at scale.
A modern study companion, tuned to the code.
VoltExam serves real exam questions tagged to the exact code section. Instant explanations grounded in the actual jurisdictional code book. A progress engine that finds your weak spots.
Five-minute drills. Picks up where you left off, remembers what you got wrong. Built to fit between jobs.
From apprentice to journeyperson, across the field.
We started with the electrical trades and grew the catalog as customers asked for more. Each app is purpose-built for its jurisdiction and code edition.
One operator. One obsession.
Today VoltExam ships 42 apps across the trades and licensed certifications, with hundreds of thousands of practice questions grounded in the actual jurisdictional code. Bootstrapped, profitable, growing.
