This seems like a very broad statement.
What is meant by "the world"?
Whoever is meant by "the world", why do they "need" more companies and why should that need factor into one's career decisions?
Why "more" companies instead of working at existing companies? Given that the most obviously influential speaker at that event is an employee at a not woman-led company, isn't that a contradiction of the claim?
Why "women-led"? Why focus on biological sex? What about intersex? How about trans or non-binary gendered?
In my view, starting or leading a company is just about the single hardest professional undertaking. You should only do it if it closely aligns with your personal purpose, otherwise it will be a nightmare experience. Encouraging someone to take a career path simply because of their association with a group, without reference to their individual objectives, is improper and will lead to an unhappy life.
