‘Zero-Sum’ is such a common term in economics and strategy – ‘one’s loss is another’s gain’. While this is largely true, this approach to profession has instilled fear and uncertainty in many a lives. We believe in just the opposite, despite being economists! The sum of skills, talents and experience of our core team members, advisors as well as clients, would keep expanding to the infinity. None of us is going to lose due to another’s success. All of us are going to be upwardly mobile as we grow. In other words, we take upon the interests of our clients and employees as our very own and strive hard to achieve them. We also work diligently to form alliances with several other firms, so as to keep the sum of all our synergies as infinite!
"We also got inspired from the ancient Indian literature (Isopanishad), which may be interpreted to mean ‘The Whole is infinite; it stays infinite despite adding or removing infinity from it’. There are several explanations to this verse, here is one for example:" The Verse.
"The following book elaborates on this principle with practical explanations that have also served as an inspiration for our name and mission:" The Book.
