Meet the Founder
Built what he wished he had.
A licensed mariner, marine engineer, and self-taught developer, Alex started Sea Trials between voyages while studying for his own USCG license exams. Eight years later, it’s a platform built from scratch for the USCG exam: our own apps, our own question bank and our own offline sync, not off-the-shelf course software.
