Mumbai, Aug. 18 -- KKR-backed human resource and payroll services provider Darwinbox is drawing buyout interest even as it prepares for a potential public listing over the next couple of years. Existing investors Salesforce and Microsoft, along with US-based HR and payroll services provider ADP, have approached its founders and board with the intention to buy others out, three people with knowledge of the development said.

Darwinbox was valued at around $1 billion when it raised $140 million from KKR and Partners Group in March last year.

"All the options are on the table. That is the beauty of the current capital markets in India," one of the persons cited above said on the condition of anonymity, as these discussions are private.
