Nadiem Makarim, once hailed as the star of Indonesia’s digital revolution, left his unicorn startup to become education minister. He’s now facing the prospect of 18 years in jail if found guilty of corruption during his public service.

The 41-year-old has been charged with alleged graft over a government decision to purchase more than a million Google Chromebook laptops for schools in 2020-2022. Prosecutors have accused him of pocketing 809 billion rupiah ($46 million) as a reward for awarding the contract to Google, which was an investor in his former company Gojek, and causing 2.2 trillion rupiah in state losses.

Makarim has denied wrongdoing, arguing the investigation was “flawed” and prosecutors failed to prove any of the charges. He said choosing ChromeOS was not a ministerial decision, while using that particular operating system helped save the state trillions of rupiah. Far from enriching himself, his personal wealth dropped by more than 50% during his tenure as a public servant, according to his lawyers.
