Deeun Inc. is a Canadian software company, founded in 2022, that builds modern exam-prep software for the skilled trades. It is independent, bootstrapped, and profitable, with no outside funding. Its flagship product is VoltExam.
Deeun builds VoltExam — a family of mobile and web exam-prep apps covering 42 licensed trade and certification exams.
