Ritesh Agarwal-led OYO will invest $10 million in the US-based G6 Hospitality, which operates Motel 6 and Studio 6. The company will channel the funds into growing the Motel 6 website and the My6 mobile app, with the goal of boosting app downloads by 4X before the summer season. Last year, OYO acquired G6 Hospitality from Blackstone Real Estate.
