MindTree is known as the fastest company to have surpassed the $100 million revenue mark—a key milestone in the IT services lifecycle. But the Bangalore-based technology firm has one more claim to fame—that of doing business with a heart. And at the cornerstone of this unique culture is a value system that MindTree minds (as they like to call themselves) dub ‘CLASS’. It’s an acronym for Caring, Learning, Achieving, Sharing and Social Responsibility. CEO & MD Krishnakumar Natarajan puts this in perspective, “Everything we are, everything we do and everything we believe in revolves around our CLASS values and the distinct culture that we have built.” And it’s not just talk—CLASS values are given a 40% weightage in annual appraisals.
