When Mr. Toby Cai and his friends were backpacking in Thailand two years ago, they wanted to book a hotel room for the afternoon to freshen up before a trekking expedition. Unable to find one, the trio wound up paying for a night's stay, but left after 3 hours. Walking through the corridors they also realized many rooms were empty during the day. That was our “aha” moment. We realized there was a need for instant daytime bookings, says Mr Cai, 32, one of three co-founders of Stayr.
