Cogent Entertainment Marketing, with offices in New York and Los Angeles, specializes in talent procurement, influencer marketing and experiential activations. The company offers perks like adoption assistance, gym memberships and ClassPass subscriptions, and unlimited paid time off after a year of employment. There's also a serious emphasis on snacking: Employees are treated to spontaneous lunches from Shake Shack and Chick-fil-A, outings to get Nutella mini-cones, field trips to Eataly and in-house Rise nitrogen cold brew. Oh, and there's also the occasional free in-house massage to boost morale.

When the 22 U.S. staffers at House of Kaizen, with offices in New York and London, aren't focusing on performance marketing in digital media, they might be blowing off steam with team-building activities like zip-lining, egg hunts, trivia games and even impromptu dance parties. The agency, which also hosts an annual HoK's Got Talent event, gives staffers the option to work four days a week for 85 percent pay and full benefits. And to reward staffers, 57 percent of whom are female, the shop hands out birthday gift cards and work anniversary presents, such as hot-air balloon rides and designer bags. Plus, there are summer Fridays off and early-off Fridays the rest of the year.

Digital marketing company Path Interactive has perks that range from the serious (health insurance deductibles 100 percent paid for by New York City-based Path, even for families) to the silly ("Mortal Kombat" and "Pac-Man" video games in the office to blow off steam). Employees can volunteer during the workday to read to kids through Pajamaprogram.org, which provides new PJs and books to children at shelters. The company also schedules and pays for a weekly fitness class for employees and takes them on a weekend outing to Montauk, New York, which involves a band and a party at the CEO's house.

PMG, the digital marketing agency headquartered in Fort Worth, Texas, calls itself "small but mighty." It has just over 100 employees worldwide but seeks to keep its "talented and tenacious" group tightly knit across its other offices in Austin, Los Angeles, New York and London. The company promotes flexible work schedules and locations. PMG's annual holiday party is two nights at a luxury resort, where significant others are invited and each employee receives a free round of golf or a massage. Other odds and ends: a $250 gift card to new parents for diapers, monthly team-bonding trips to go bowling or go-karting, and free in-office yoga twice a week.

Free Cubs tickets and half-day Fridays might seem like a scene out of "Ferris Bueller's Day Off," but it is a way of life at Chicago-based digital marketing agency Be Found Online. The perks are part of a generous benefits package offered at the shop, whose services include search engine optimization, social media and web analytics. To recognize standout employees, the agency hands out "golden tickets"; the person with the most each month gets to spin a prize wheel, with giveaways including cash and round-trip airfares. Be Found Online is also so dog-friendly that it once tried to offer pet insurance as a perk, though it didn't get any takers.

If flexible hours and perks like giving stipends for setting up workspaces to team members who live more than 50 miles from an office weren't enough, New York City-based Elite SEM offers its staff unlimited paid vacation. Employees also laud the 163-person digital marketing shop, which is more than half (53 percent) women, for having a "friendly and relaxed work environment" and an approachable leadership team. Plus, this crew spreads its happiness, supporting community service projects with its Get Up & Live committee and working with the likes of Habitat for Humanity and Ronald McDonald House.

The agency that spelunks together stays together? Exploring a local cave was among the activities that employees at this Bloomington, Indiana-based agency partook in during one of the stress-relieving outings the shop organizes a few times a year. Other generous perks at the digital marketing shop include 20 vacation days after just one year of service and a quarterly "rest and rejuvenation" day off. When employees are at work, the agency takes education seriously, holding weekly training sessions and monthly deep dives with in-house and third-party experts. Hanapin also values one-to-one training, offering a mentoring program in which employees pair with an internal or external mentor.

The Indianapolis-based independent creative shop keeps the minds and bodies of its staff healthy with shower and locker facilities, bike racks, yoga classes and even a "quiet room" for meditation, prayer or just a mental break. At a time when women are underrepresented in the industry, half of Young & Laramore's 50 staffers are female. To keep employees inspired, the shop offers every staffer $100 per year for an activity or purchase that sparks his or her creativity. On "Beer Thursdays," the staff comes together to review recent work and drink some suds. The company's organic office garden and green wall covered with potted plants aren't bad touches either.

If you've ever shared a story or photo online, you've likely used the technology Sharethis created. The Palo Alto, California, company provides a share button that tracks what people are sharing as well as how many clicks those shares received. But with employees, it also shares the fun. It sometimes substitutes conference room meetings for walks, holds regular poker and game nights, and has an in-house exercise facility with a pull-up bar, yoga mat, elliptical machine and dumbbells.
