Our Story



We chose the unique Tuatara as our company name because it embodies key attributes that, like us, sets them apart from the pack and has enabled them to navigate and thrive in unique environments. Tuatara,  although they resemble lizards, are part of a distinct lineage that has existed for the past 200 million years through their ability to evolve and adapt to their surroundings.  Their physical characteristics add to their uniqueness. These tenacious creatures have a spiny crest along their back, a third eye, and a double row of teeth that interlocks with their bottom teeth – a perfect mascot for a boutique consulting company that offers insightful analysis, adapts to rapidly evolving markets, and helps its clients to identify, carve out and secure their niche in challenging markets.
