A still unquenched capacity for growth.

As you page through, bear in mind that this list is not intended as an endorsement of any particular franchise. Even the hottest concept can grow cold in the wrong hands, so always take your time to do your due diligence before you invest. Review all legal documents, consult with an attorney and an accountant and talk to as many current and former franchisees as you can.

Children's Enrichment

Kids have become some of the franchise world's favorite customers, with parents willing to shell out to help their little ones thrive. In this category, franchisees are drawn to opportunities that are often low-cost, flexible and able to be run from home.

Electronics

It's no surprise that with smartphones and laptops in almost everyone's hands, a booming franchise industry has sprung up around selling and servicing them—with repair businesses meant to get this tech back in action fast proving particularly popular.

Entertainment/Recreation

Consumers in search of new and creative leisure activities have spawned a slew of new franchises focused on fun. From video game theaters to trampoline parks to paint-and-sip studios, there's something for every age and interest.

Fitness

Year after year, fitness franchises continue to pack a powerful punch. Big, traditional brands have proven their staying power, but it's the boutique concepts—focused on everything from barre to boxing to basketball—that are really shaping the industry today.

Hot Dogs

When Burger King added them to its menu earlier this year, we knew the humble dogs' time had come. But these aren't necessarily classic dogs of yore. New, daring concepts are elevating the old-fashioned frankfurter with gourmet and unexpected ingredients sure to appeal to the foodie crowd.

Pest Control

Outdoor-pest-control companies have been growing steadily for several years. Now, with the growing concerns about the spread of the Zika virus—not to mention other mosquito- and tick-borne illnesses—their services are going to be even more in demand.

Pets

People love their pets. For proof, check out how much they spend on them. The American Pet Products Association estimates that 2016 spending on Fido and Fluffy will total $62.75 billion. So it's no wonder numerous franchises are finding success serving the four-pawed and furry.

Resale/Consignment/Estate Sales

Everything old is new again, now that buying used has become trendy. It's not just for clothes, either; you'll find resale franchises selling toys, books, and even gift cards. And for the true treasure-seekers, there are consignment-event and estate-sale franchises as well.

Restoration

Restoration may not be the most glamorous industry, but it is one of the most indispensable. No matter the time or place—or economic climate—there will always be disasters, and there will always be a need for someone to clean up after them.

Staffing/Recruiting

As the job market continues to improve, staffing and recruiting franchises are flourishing. Agencies offering everything from temporary staffing to executive recruitment all benefit from having two sets of clients—both the companies looking for workers and people looking for work.
