About Us

We are defined by what we do

Our passion for Bali's history, traditions, and environment are at the heart of all we do at Mantra. Founders Maitri Fischer and Sean Nino Lotze grew up on the island and had the privilege of experiencing Bali in the 1980s and 1990s, a simpler time when the natural beauty and magic of Bali was everywhere. It is something we strive to continue. We remind our partners about the luxury that is Bali's nature. At Mantra everyone dedicates their time on built environments and solutions that offer a very high quality experience, with minimal natural resource needs. Mantra partners with Indonesia's best universities, business leaders, and local communities to improve the sustainable development of the country's tourism industry. This is Mantra Bali. 

Mantra works on environmental management and monitoring solutions

Change and development is inevitable, but that it comes at the continuous cost of the environment is not. The environment is a very complex system that functions within ecosystem boundaries. Our team works on building an understanding of these boundaries and provides tools that show how many resources are really being consumed and how much is being wasted. 

Mantra makes it easy for properties to become environmental friendly by measuring and improving resource consumption, developing standards for sustainable engineering design and construction, and providing green building certification. Mantra takes historical records and brings forward the stories and solutions that inspire green leadership and real sustainability. Mantra also provides the right tools for teams to tackle problems with energy and intelligence and provides guidance to improve the ecosystems around us. 

Mantra was featured on the International TV Series “Founders Valley” and showcases water saving solutions in the episode Sacred Water, Scarce Water. The show was aired in the 30 countries and languages, on the Deutsche Welle DW Network.

It is often too easy to lose sight of the larger meaning of our work. Whether a technician or manager we all become immersed in our daily activities, focusing on the "what" part of the equation. We put the "why" at the forefront. We guide people to find the right environmental solutions on their own, so that environmental management becomes their natural inclination.
