Ida Tin

This woman built the #1 period-tracking app.

Ida Tin wanted to be an artist.

Then, she accidentally walked into the wrong interview room and ended up enrolling at Kaospilot, a progressive business school in Denmark.

That twist of fate set her on the path to entrepreneurship.

In 2012, she co-founded Clue, one of the first period-tracking apps, giving millions of women a way to understand their bodies beyond guesswork and stigma.

But her impact didn’t stop there.

In 2016, Ida coined the term “FemTech”.

Giving a fragmented industry a name, an identity, and a rallying cry for investors.

The result? A booming market tackling menstruation, fertility, menopause, and sexual health, now projected to be worth $1.186T by 2027.

But behind the buzzwords was a brutal truth: women’s health was still shockingly underfunded.

“We’re still getting peanuts to play with when you see the amount of money invested in, you know, e-scooters, car sharing… We have to prove ourselves so much harder.”

Clue grew fast.

Within six years, the app had 10M users across 190 countries.

Even Apple, one of the world’s biggest tech companies, had to call her in to help develop their first period-tracking software.

And yet, Ida’s journey didn’t start in a boardroom.

Before Clue, she spent five years leading motorcycle tours across the world.

Riding through Mongolia, Cuba, Vietnam, and the U.S., writing a bestselling book about her adventures.

Even as a child, she grew up on the road, traveling with her parents on motorcycles from South America to Africa.

Maybe that’s why she had the courage to build something from nothing.

Today, Ida is an active voice in the FemTech movement, pushing for better investment, better data, and better solutions for women worldwide.

She stepped down as Clue’s CEO in 2021, but her fight isn’t over.

She’s now writing a book about the industry she helped create.

Her mission? To make investing in women’s health as obvious as investing in the next iPhone.
