Entrepreneurs are professional problem solvers. They look at what’s broken and find a way to make it right. This year had its share of great solutions, big and small, from ingenious ways to keep delivered pizza hot to an innovative way to catch cancer early.

To send off 2016 right, we asked our staff of editors and writers to round up the solutions they liked the most. It’s our way to toast the entrepreneurial innovations that continually shape our lives while showcasing things that might not have made your radar.

Zume Pizza

For pizza lovers: A better way to deliver pizza

Solution: Zume Cooks pizzas en route, ensuring hot and ready pizzas every time.

Our Take: “When I first heard about Zume Pizza’s pizza-by-robot model, I wanted to mock it. But I admit I had to put my cynicism aside when I talked to Julia Collins, the company’s co-CEO. As she eloquently and expertly answered all of my questions, I became convinced of the company’s mission. I’ve lived in the New York bubble all my life, where fresh and tasty pizza can be found on every other block. Collins rightly pointed out the rest of the country doesn’t have such luxuries. This is a Silicon Valley innovation I can salivate over.” — Stephen Bronner

Google

For nostalgia buffs: A new life for old-school film

Solution: Photoscan, a free app from Google, helps you make enhanced, glare-free digital scans of old-school photos.

Our Take: “For most people, your wonder years were captured on film — you know, that real-world material that needs to be processed then printed out on paper. Someone at Google recognized the need to easily convert these paper memories into digital ones, and maybe even have an easy way to embarrass a sibling with an awful outfit he or she once wore.

I’m pretty sure my mom could use this app without much explanation. Perhaps over the holidays, families should set out to create digital versions of old photos — preserving them for the next generation.” — Stephen Bronner

Zocdoc

For workaholics: A guilt-free reminder to schedule that dentist appointment

Solution: ZocDoc, a medical scheduling service, has partnered with companies to encourage time off for check-ups.

Our take: “When I heard about Zocdoc’s idea for an ‘Unsick Day,’ I thought, ‘Now that would get me to go to the dentist.’ It’s a new kind of paid day off (like vacation or sick days) that encourages employees to schedule and attend health-care appointments even when they feel well.

I’m young and healthy, and I put off preventive care because I never feel like researching health care providers when I get home after work. I know my boss wouldn’t mind me taking a few hours off to go to an appointment, but some unspoken societal stigma stops me. (Which is illogical, because she stepped out for an afternoon dental appointment last week!) But I’m not alone. I discovered earlier this year that nearly 60 percent of Americans put off preventive checkups and 80 percent would still put work first if they had an appointment on the books.

I receive (and underutilize) benefits from Entrepreneur Media, and the company is invested in me being healthy and productive to write articles like these. An Unsick Day might get me to stop making excuses — and get me to own up to my bad flossing habits.” — Lydia Belanger

Uber

For safety: Autonomous trucking

Solution: Self-driving big-rig trucks

Our take: “Self-driving isn’t only for cars. Big-rig trucks are also becoming autonomous. That’s important, because a full 1 percent of vehicles in the U.S. are trucks. Which might not seem like much — until you realize that they drive 5 percent of the miles and are responsible for 10 percent of the fatalities on the roads.

While the self-driving space has a number of players, one company stood apart in 2016. Otto, co-founded by former Googlers Lior Ron and Anthony Levandowski, combined backgrounds in hardware, mapping and machine learning to build kits that can be installed in existing freight vehicles. Once installed, trucks drive on America’s freeways with little (if any) human intervention and ensure that trucking companies won’t need to wait years to replace their fleets. It’s a solution that got noticed quickly. Otto launched in January, and by August, Uber announced it had acquired the company.

The startup’s success has implications beyond just trucking. As Ron told Entrepreneur this summer, the more of these trucks people see on the roads, the sooner the government and public will warm up to the idea of self-driving in general.” — Lydia Belanger

Zipline

For those in need: Help from above

Solution: Robotics company Zipline International Inc. delivers blood to remote areas and developing countries.

Our take: “While it has been in beta for the last five years, Zipline finally launched this year. Using drones, or mini airplanes, the company is able to deliver medicine to people in need. According to its website, there are more than 2 billion people who don’t have access to medical products, resulting in 2.9 million children under the age of 5 dying each year and 150,000 pregnancy-related deaths. With Zip, the name for the flying devices, now medicine, blood and vaccines can be delivered to hard-to-reach places, and give aid to millions.” — Andrea Huspeni

Nuzzle

For pet owners: A way to find Fido, every time

Solution: Nuzzle, a special tracking collar, uses GPS to tell you what your pup does all day.

Remedy

For savvy spenders: An end to costly billing errors

Solution: Through Remedy, a team of experts — including many who worked for insurance companies — will look at someone’s medical bills and assess whether errors have been made.

Our Take: “Billing errors are so prevalent this startup has made a business out of correcting them. If Remedy does not believe a claim to be correct, its team will get on the phone, go through all the hoops and dispute the bill. The startup claims it saves, on average, families $1,000 a year. The company takes 20 percent of what it saves the customer but caps its take at $99. The service is a boon for anyone feeling powerless against the medical system. We like that it helps people focus on their health more and their bills less.” — Andrea Huspeni

For a cure: A game-changing cancer test

Solution: Grail is a noninvasive method to check for cancer earlier than had been previously possible — at a curable stage or before a person shows any symptoms. It has an ambitious goal to develop a universal cancer screening test. The company has received $100 million from investors, including Arch Venture Partners, Bezos Expeditions, Bill Gates and Sutter Hill Ventures.

Truebill

For spending sleuths: Seeking out mystery charges

Solution: Truebill is an app that scans your credit card bills to let you know what you’re being charged for every month including subscription services and recurring bills such as Comcast or AT&T. Truebill will also cancel any unwanted subscriptions for you and notify you of any changes in your subscriptions and bills.

Pearl Auto

For car owners: Making old cars new again

Solution: Pearl updates existing cars with new technologies, such as RearVision, a solar-powered backup camera. Just affix the license plate frame (with cameras attached) to your car and enjoy the backup camera system that’s now standard with many new cars.

Jiobit

For parents: A better way to keep tabs

Solution: Jiobit’s “invisible wearables” are designed to discreetly fit into children’s clothing, helping parents monitor their kids. The system also integrates into a family’s smart home system.

Nima

For the food allergic: Putting people at ease

Solution: The Nima Sensor, set to ship to customers this spring, tests whether something contains gluten in three minutes or less. The company is also at work making tests for the other major allergens such as peanuts, shellfish and dairy.

Softbank

For all humans: A step toward better robot relations

Solution: Pepper, a humanoid robot from Softbank Robotics, fills a variety of roles, from a product expert to a health care aid to a concierge, emphasizing more nuanced interactions with customers. First launched in 2014 in Japan in cell phone stores and at Nestle kiosks, Pepper made it made its U.S. debut this holiday season to help shoppers in Westfield Malls in the Bay Area in California.

Our take: “I actually got to meet Pepper this fall, and got a brief sense of what it would be like to live in a world populated with robots. It was an odd experience, but an illuminating one — face to face with the helpful machine, my first inclination was to be perfectly polite, because I guess you never know.” — Nina Zipkin

Lucky Iron Fish

For health: A simple fix with a big impact

Solution: B-corp Lucky Iron Fish developed a cast iron “fish” that can be placed in boiling water to add iron to meals. The food made with the fish can meet 90 percent of a family’s daily iron intake for up to five years.
