Alsephina is a newly named star in the southern sky. It means “the ship” in Arabic and was once part of a much larger constellation known as Argo Navis on which the Argonauts were said to have sailed. Generations have gazed up at the stars, weaving stories of their quests.
At Alsephina Consulting, we help companies connect-the-dots in new ways as they chart their growth. Our focus is on people, teams and organizations. We bring tools of organization design, behavioral science, people analytics, network analysis, innovation systems and classic human resources to understand and craft new stories as they are emerging.
