About Us

At Decobu, we care about two things, doing good work and being good to work with. We started in Perth and now have teams in Sydney, Melbourne and Manila. We’ve grown by keeping things simple: listen, design properly, talk straight, and do what we say we’ll do.

Good engineering isn’t about talk, it’s about keeping the lights on.
