Hotel-reservations startup Oyo is in advanced discussions to raise $100 million (Rs 697.7 crore) from Singapore-based ride-hailing company Grab as part of its ongoing $1 billion funding round, The Economic Times reported. SoftBank-backed Grab, which acquired ride-hailing company Uber’s Southeast Asian business in March, is likely to close the deal in the next few days, two persons in the know told The Economic Times. Emails to Oyo did not get a response till the time of publishing the report while Grab declined to comment.
