These women are starting something.

On Wednesday, professional networking site LinkedIn released its list of the top startups — a list that highlights “the top 50 startups disrupting their industries.” To be included, these independent and privately held companies in the U.S. and U.K. had to be no more than 10 years old, have more than 100 employees and have had at least one round of venture-backed funding.

The usual suspects top the U.S. list: ride-sharing companies Uber and Lyft; home sharing site AirBnB; coworking firm WeWork; and office communication tool Slack are in the top five. (See full list below.) But there’s at least one unique thing about this list that may not immediately be obvious: Women run many of these companies.

Indeed, more than one in 10 (12%) of the companies on the list are headed by women, which is double that of female CEOs on the Fortune 500 list. The highest ranked company with a female head is car company NIO (No. 6 ranked on the list), fronted by Padmasree Warrior, who writes on her LinkedIn profile that the mission for NIO is to deliver cars that are “safe, green, efficient and accessible to millions around the world.”

Other women on the list include Adi Tatarko, who rules the roost at home design site Houzz (No. 9), Emily Weiss at cosmetics firm Glossier (No. 13), Katrina Lake at clothing delivery service Stitch Fix (No. 32); Nicole Egan at cyber defense firm Darktrace (No. 35) and Deborah Nicodemus at clothing firm Moda Operandi (No. 43).

But having women at the helm of your company isn’t just good for optics, it may also help boost your bottom line, research shows. A study of nearly 11,000 publicly traded companies by Scandinavian bank Nordea released this year found that firms with women at the helm — either as the CEO of head of the board of directors — perform better than the market with a 25% annualized return since 2009.

No matter which gender sits in the driver’s seat, the culture of perks at these startups remains strong — and growing. Among the most unique: An onsite spa with manicures, pedicures and massages at Credit Karma, as well as rooms for music jam sessions and an art room; a rule of “no meeting Wednesdays” at Glint; branded slippers at Houzz; and a personalized bitmoji from G2 Crowd.
