Cue, a calendar aggregator, was sold by a 21-year-old Israeli living in California to Apple, Inc. for millions.

Tech giant Apple, Inc. will pay some $40 million or more to acquire a start-up created by 21-year-old Israeli Daniel Gross, formerly of Jerusalem, and now living in California, tech media reported at the weekend.

Israel’s Calcalist website said Gross is a native of Katamon, Jerusalem, a yeshiva high school graduate and has been on pre-military leave. He planned to serve in the IDF after high school, but changed course after a small start-up he created generated interest in Silicon Valley.

Origianally called Greplin, his company was renamed Cue and raised $10 million from Index Fund, Lerer and a group of angel investors in Silicon Valley, Calcalist said.

The Cue service aggregates appointments across a user’s social media accounts to make managing them simpler via a calendar function. The company’s employees will soon move to Apple.
