The Firm

Our clients are unique; Hapax is too.

In linguistics, a hapax legomenon is a word or phrase that appears only once in an entire corpus — it's utterly unique. Determining what a hapax means is challenging, even if you know the language.

At Hapax, we believe our clients' needs are similarly one-of-a-kind. Each one demands careful, individualized analysis. We use cutting-edge technology to work efficiently, but we rely on human wisdom and experience to find unique solutions to unique problems.
