Back in the day, 23andMe was one of those vaunted "unicorns" (privately held startups valued at more than $1bn), but is now facing harder times. Its share price had fallen precipitately following a data breach in October 2023 that harvested the profile and ethnicity data of 6.9 million users – including name, profile photo, birth year, location, family surnames, grandparents' birthplaces, ethnicity estimates and mitochondrial DNA – and there have been internal disagreements between its board and the CEO and co-founder, Anne Wojcicki. So on 24 March it filed for so-called Chapter 11 proceedings in a US bankruptcy court in Missouri.
