Meet the woman who invented a whole new subsection of tech set to be worth $1 trillion

Ida Tin accidentally enrolled in a business course at college when she intended to study art. As a result, she became a pioneer in a field that is expected to be worth more than $1 trillion.

As she described her initial steps into the business world, Tin remarked, "I genuinely got lost in the hallways and I ended up in some office where they were waiting for a candidate to perform [the business course interview]".

She enrolled in the school and subsequently used her creative talents and entrepreneurial spirit to launch a jewelry business, a motorbike tour business, and finally, in 2012, Clue, a menstrual health app with 11 million active monthly users.

One of the first period tracking applications was Clue.
