When it comes to employee perks, there's no beating Silicon Valley.

The tech industry is famous for its cushy new-age offices, workplace foosball tables and progressive benefit packages, and it seems those indulgences are paying off in worker happiness. The tech industry dominated Glassdoor's annual list of the best companies to work for this year, accounting for nearly half of the top 50 spots. The ranking is based on a survey taken by employees at each company, and it's usually full of surprises.

This year's surprise: Airbnb, which has found little love among local governments or affordable housing advocates, was voted the best in America, according to its own employees. The home rental startup dethroned Google for the top spot this year, while the search giant fell all the way to number eight.

Following closely at Airbnb's heels are management consultancy Bain and Company, insurance software provider Guidewire, marketing software developer Hubspot and Facebook to round out the top five.

The ranking is a testament to the heated competition for talent in the tech sector, where companies try to outdo one another with bigger perks and benefits in order to attract and retain a relatively limited supply of skilled employees.

Here are some of the highlights of this year's list. The rankings represent their placement on Glassdoor's list.

1. Airbnb

Company Rating: 4.6

Apparently battles with local regulators and an ill-conceived ad campaign in San Francisco didn't sour Airbnb employees' opinion of their workplace. The company, which is said to be valued at more than $25 billion, offers maternity and paternity leave well above industry standards and quarterly travel vouchers among other workplace perks.

“The people that work here are some of the best I've met in my professional career," said one employee. "The culture is good. The founders are great people and I believe they have the best intentions for the company, the employees, and our community."

This year marks the first time Airbnb has appeared on the list.

3. Guidewire

Company Rating: 4.5 Business: Software

The Foster City, California-based insurance software company ranked third place overall but snagged the number two spot on the tech list. “Guidewire hits the sweet spot between ‘startup culture’ and ‘big corporate culture,’" said one employee based at the company's Bay Area headquarters. "There is the small company vibe, wherein you can talk to everyone and get things done. And there is enough room for flexibility in processes for individuals and teams to choose what works best for them, while having the support of the larger organization.”

4. Hubspot

Company Rating: 4.4 Business: Software The sales and marketing software company fosters employee connections through events like "mystery dinners," where it brings together an assortment of people from different departments and buys them a meal.

With programs geared specifically towards female employees and an executive slate comprised of about one quarter women, the company was also ranked one of the best workplaces for women by Fortune.

“Leadership places a heavy emphasis on employee growth across all divisions, from tuition reimbursement to offering opportunities to take on challenges outside your core responsibilities," said one employee.

5. Facebook

Company Rating: 4.4 Business: Social media

The social network stepped up its already progressive benefits this year by expanding parental leave to four months for employees worldwide — a policy which CEO Mark Zuckerberg has been taking full advantage of over the past week.

The company also offers assorted other perks to its nearly 12,000 employees, spanning everything from video game rooms to a somewhat controversial egg freezing option for women. “The culture is really amazing and in my opinion even better than the media portrays it," said one Menlo Park employee. "The perks are wonderful, but the professional experience is even better! I feel the energy everyday working here.”

6. LinkedIn

Company Rating: 4.4 Business: Social media

As a career-oriented social networking site, it makes sense that LinkedIn is well-acquainted with how to keep its workers happy. Perks like dedicated time to work on special projects, events featuring world-renowned speakers and generous professional education stipends make the company a frequent appearance on the list. “Our culture is about transformation, integrity, collaboration, humor, and of course results," says one worker. "This culture drives everything we do and is supported by the company's core values that every employee knows and lives each day. Our values are grounded in our members who come first always.”

The perks are unbelievable (food, massage, gyms, discounts, etc.) but the best part is being surrounded by such amazing talent. It's truly inspiring.” – Google Interaction Designer(Mountain View, CA)

10. Zillow

Company Rating: 4.3 Business: Real estate tech

After the New York Times published a scathing investigative piece on Amazon's intense work culture earlier this year, Zillow CEO Spencer Rascoff got himself in a bit of trouble for tweeting, "Amazonians — you are welcome @Zillow" with a link to the article and the hashtag "#NowHiring."

It was a brash joke, but the former investment banker says he is completely serious about building a softer workplace culture that's miles apart from the brutal Wall Street lifestyle with which he started his career. “The views are amazing, the free food/snacks/drinks are great, and the benefits are great," a Zillow data scientist said. "I'm surrounded by smart people, and am constantly learning. Little red-tape and no business politics allow for us to immediately benefit the company and have a huge impact.”
