Our name

“On my trip to Easter Island in early 2017 I was impressed by the monolithic giant statues (or Moai) carved by Rapa Nui people on the island between the years 1250 and 1500. They represent ancestors of the local people and were carved out of the rocks and put at the beaches to protect the people.

Alhough moai are whole-body statues, they are erroneously referred to as “Easter Island heads” in some popular literature. This is partly because of the disproportionate size of most moai heads; almost all moai have overly large heads three-eighths the size of the whole statue.

These heads inspired me to make sure that our clients’ get the no nonsense support they need and can be successful in their business. It is by going to the basics and communicating what really matters that you can make an impact. That is when you are talking.”
