Amid the ongoing fallout from widespread sexual assault and harassment allegations and the #MeToo campaign, gender equality is high on the Davos agenda this year, but the elite annual gathering still has its own issues to solve.
Gillian Tans is softly spoken and unassuming. The 47-year-old isn't someone you'd immediately associate with power. Yet she has a lot of it.
As the chief executive of online accommodation website Booking.com she's in charge of a staggering 15,000 employees in 70 countries around the world.
In 2016, she earned an impressive $17.1m (£12.3m; €13.9m). That was more than her own then boss at US firm Priceline which owns Booking.com as well as other travel related brands including Kayak and rentalcars.com.
In the world of business, a successful woman on this scale is still pretty rare.
