Fifty-six years of building on belief.
What started in 1968 as a small group inside an Indian conglomerate is now one of the largest professional services firms in the world, part of the global TCS group and incorporated in England & Wales as a Public Limited Company. The mission hasn't changed: help organisations build a better future, by doing the hard, durable work of transforming how they actually run.
A partner that's still here in year twenty-five.
We aren't a firm that arrives with a deck and leaves with a check. We embed. We train. We run. We hand back. The average tenure of our top 100 client relationships is over 17 years - not because contracts are sticky, but because outcomes are.
That's what "building on belief" means: a belief that the engine of progress is patient, long-running partnership - the kind that survives strategy resets, leadership turnover, and the next wave of technology.
