BENGALURU: A management reshuffle at data analytics firm Mu Sigma has catapulted Ambiga Dhiraj to the top post, making her the first woman chief executive of an Indian technology company that’s worth at least $1billion.“I want to create the most resilient organisation, one with the proper foundation to support our growth over the next five years,” said Ambiga Dhiraj, who until recently was chief operating officer at the 11-year-old company.“We will be a $1-billion (nearly.`6,800 crore) revenue company soon. We’re going to get there in a smooth manner. That’s what I want to go after.” She will continue to be based in Bengaluru. Her husband, founder-chairman Dhiraj Rajaram, whom Ambiga has replaced as CEO, will relocate to the United States.This will enable him to engage more directly with clients, 140 ‘Fortune 500’ companies among them. He will also spend time designing new offerings for the company’s man-machine ecosystem and forge strategic alliances.“We are conquering this in two different ways: one person who will make sure we are excellent at execution and another who’s going to unleash himself on helping large enterprises capitalise on the promise of big data,” said Ambiga, adding that the company aims to sign up to 10 new customers in every quarter this year.Named after Greek symbols used as mathematical notations, Mu Sigma has received nearly $200 million in risk-capital funding so far from marquee investment firms including General Atlantic, Sequoia Capital and Fidelity Investments The company was valued at about $1.5 billion at the time of its previous fundraising round in February 2013, when MasterCard teamed up with Fidelity Investments to put in $45 million for about a 3% stake.“We support and recognise this change as yet another sign of Mu Sigma’s growth,” said Shailendra Singh, managing director at Sequoia Capital India. “This move will unleash Dhiraj to help large enterprises capitalise on the incredible amount of change they’re facing.”Mu Sigma, which employs 3,500 scientists in 10 industries, recorded revenue of $250 million in 2014-15. Ambiga said the company had no plans to publicly list its shares for the next 3-5 years. “Mu Sigma is moving from its adolescence into its prime. Our purpose as a company will never change but we must occasionally change how we pursue that purpose,” said Dhiraj Rajaram.The management styles of the husband-wife duo are vastly different: Ambiga said both of them are quick to agree on the “Why” and “What” of Mu Sigma, but can differ in the “How” —the manner in which things get done. She’s one to get into granular levels of detail and deliberate over matters of design, while he’s someone who wants to see quick results.“At this stage of the company, our style differences will probably be visible. This will set us up for a nice foundation as we embark into different regions and different parts of the globe,” said Ambiga.Globally, few women hold top positions at Unicorn firms, those that are valued at over a billion dollars. Ambiga now joins the league of CEOs of healthcare firms 23andme and Theranos and media firm Houzz. Ambiga said her main challenge will be in balancing the processes and structures of a young, hi-growth company while not diminishing its vibrancy or agility."She will inevitably get compared to Dhiraj and that’s something that she’s got to be prepared for. It’s important to not worry about what others think and just work with the best team,” said Shanti Mohan, a serial entrepreneur who founded two technology startups in Silicon Valley prior to founding deal-making platform LetsVenture in India.
