15 of the coolest small businesses in the US right now

What it does: Offers passengers free rides to some beaches in the Hamptons, the Jersey Shore, Santa Monica, and San Diego. How? Electric cars eliminate the cost of fuel and the service is sponsored by advertisers (like JetBlue, seen in the photo).

Why it's cool: Beach-goers no longer have to drive themselves crazy looking for (and paying for) a few hours of parking. Plus, electric cars mean the service is environmentally friendly.

What it does: This mother-daughter-run business sells high-quality shea-butter products while supporting fair wages for the female workers in Ghana who make those products.

Why it's cool: Eu'Genia Shea donates 15% of its profits back to their female workers in Ghana, either in the form of a retirement fund or an education fund for their children. Each product comes with a personal touch — Akuete and her mother package them themselves in her Brooklyn apartment.

What it does: Helps teachers personalize math instruction through an artificial intelligence-enabled math education platform. The program provides interactive exercises for students and then delivers feedback to the teachers based on the students' performance.

Why it's cool: One-on-one education can be more effective than conventional classroom education, but that's not always realistic. HappyNumbers makes it possible. Plus, it helps smart, high-potential students who are nonetheless struggling (like Milyutin, a physics PhD who had a hard time with math in elementary school).

Why it's cool: There's no getting around it: New York City is running out of bookstores. Straub and Fusco-Straub are among a growing group of entrepreneurs trying to change that, to the delight of bibliophiles in all five boroughs.

What it does: Allows users to create apps based on different interests and launch them through the Amino platform. Apps that are popular enough become stand-alone apps in the App store.

What it does: Lets customers order from local pizzerias (that aren't necessarily on services like Seamless) through a mobile app.

Why it's cool: CEO Ilir Sela's family has been in the pizza-making business for generations. His goal with Slice is to help local pizzerias making delicious pizza stand their ground against big chains making less delicious food, and against online ordering companies that favor those big chains.

Why it's cool: The US is expected to see a shortage of 90,000 physicians by the year 2025. Nomad Health allows doctors to find hospitals that really need their help. The company's CEO is a doctor himself, who saw firsthand how hard it was to get freelance work and aimed to find a solution.

What it does: Puts out a daily finance newsletter geared toward millennials.

Why it's cool: The founders, former analysts at New York banks, recently made Forbes' "30 Under 30" list. Their goal is to make financial news concise and, most importantly, "digestible."

What it does: Sells affordable, ethically sourced, high-quality gold jewelry.

Why it's cool: AUrate was initially self-funded through the founders' savings and through family and friends; the founders wanted to have revenue first, and then raise money based on that proof of concept.
