Ramnath founded Multiples Asset Management in 2009, with a focus on mid size companies and investments between $15 million and $50 million. The firm's partners include the Canada Pension Plan Investment Board which invested $100 million in 2010.[7]
Prior to founding Multiple Asset Management Ltd., Ramnath was the MD and CEO of ICICI Ventures, the venture capital arm of the ICICI Group, through the period that saw the firm become one of the largest private equity funds in India. She is credited with helping grow the fund from a $100 million proprietary fund to a $2 billion PE fund with third-party capital. In this time she is also credited with raising, managing and divesting the $250 million India Advantage fund, generating a more than triple return on capital.[7] She has also served within the ICICI Group across investment banking, e-commerce, and private equity.[8]
Some of Ramnath's venture investments include investments in Air Deccan, Tata Infomedia, and VA TechWabag.[7]
Ramnath and ICICI Ventures were also the targets of a legal action from Azim Premji's investment company Premji Invest when one of the portfolio companies Subhiksha, a leading discount retailer, ran out of cash and closed over 1,600 stores nationwide. The notice alleged that Ramnath and ICICI Ventures had not revealed the extent of Subhiksha's problems before the sale to Premji Invests.[9][7]
